replaced my lg g2 screen again for the third time and have done over a thousand phone repairs with no issues like this phone will not accept power turn on or vibrate battery was disconnected before anything was done worked perfect before except bad lcd i have no idea or what board to replace im thinking possible the battery somehow shorted,but then it should still get usb power? or the board where power button charge port and everything else connects?

Ok i got an extremely bad problem
i brought a hd2 from ebay with a fault, which was the person said he dropped the phone and the screen cracked then he replaced it with new screen and digitizer, but he said after he did that the phone only starts up sometimes, anyway i won the bid and when i recieved it i put the charger in and it turned on by itself and was stuck ar htc screen i took the charger out and the phone went off, so i put the charger back in again and it didnt turn on this time, tookout battery and did reset and hard reset and still nothing? the phone doesnt have hardspl.
so i opened the phone up and look to see if anything was lose which it wasnt and i also manged to damage the volume flex cable and the bottom buttons flex!
so i left my phone overnight and in the morning i put the battery in and put it on charge and A RED LED LIGHT CAME ON!!!! which means it was charging so i thought if i press the reset button it come on, so i pressed the soft reset and nothing came on and the red light dissapeared and it doesnt come back again?
Can anybody help me whats wrong?
Since the previous owner has dropped the phone, anything could have went wrong.
First, check the battery pins on your phone, and make sure they are straight (not bent, not eve a little)
Hi I tryed that but it still don't work, also to follow up I put my htc in fridge for 5 mins and put in usb and orange light comes on so I left it for couple of hours and after it finished charging it virbrates and screen comes on but it just stays black so I took out battery and it didn't startup, so battery is fully charged and I. Put phone back in fridge and put usb back in and orange light came on again, so this time I pull out usb cable and the light is still on??? And I pull out battery and it goes off I don't know what's wrong???? Its driving me nuts!!!
Edit - ignore what I wrote above, okay I left phone in fridge and I put battery in and then I put in usb and orange led light comes on then the phone vibrates and the htc logo screen comes up but it is frozen there and I can't reset because I have no buttons because I broke the flex ribbon. I pull out battery and it turns off and it doesn't come back on so I put usb in and then battery and nothing but I can feel a tiny bit of vibration but not as strong as before. Its soo wierd the phone only powers when I leave it in fridge.
really need a solution fast
Please guys I really need a solution, don't leave me hanging. I was going to buy a new motherboard but I don't know whether its worth it because I font want to waste money.
I can't answer your question. But I know for fact that if the hd2 overheats monsterously the processor melts off it's spot or something and the phone starts to reboot at 25-30 Celsius degrees and that could explain cooling it down lets it boot. My suggestion is to sell the phone on Ebay as SLIGHTLY damaged Hahahah!
infact thats what i done i put it on ebay if anyone wants it let me, mint condition except boot failure I don't think it the processor because I can connect to usb and it comes as qualcomm data
The phone tries to turn on because I see the vibration motor turn once but nothing else happens?
facepalm.
....
Was there any need of facepalm makes you look like a retard. Don't do it please
Hi All
My friend recently gave me his LG G2 as it had a problem.
What happens is currently if you try and turn on the phone nothing happens. When you plug the phone into the charger the red led blinks and nothing else happens. He told me that he got the phone brand new off eBay and that the problem started after he left the phone plugged in overnight. No software modifications have been done to the phone prior to the red light issue.
After some investigation into the issue i found nothing except another eBay listing with a LG G2 D802 where the guy got water into his phone and it has the exact problem where the phone does not turn on and a red light comes on when attempting to charge the phone. The eBay listing also says that the phone was seen by a service technician who said the circuit board was damaged but is repairable
Before i spend any money buying spare parts does anyone have any idea on what the problem is and whether its worth fixing?
Thanks
Could it be that the motherboard got damaged?
I don't think the mother board got damaged. I had the same problem with both my G2's. (D800 and LS980)
I had changed the motherboard from ls980 to the d800, I connect everything, LCD, digitizer, battery,front and back camera ..etc..
I go to try and power the phone up but nothing happens..
I go to plug in the phone.(Nothing happens)
I use another charger(nothing happens.)
My phone wasn't water damaged though. In your case you could open up your phone and disconnect the battery connector, After about 1-3 minutes connect it back & leave phone alone.(don't try to power up)
I had a problem with one of the phones not having the red LED light coming up to tell nevit was charging. I switch the battery to another bezel & motherboard & it shows 40% battery level.
It definitely worth a try to open your phone & disconnect and connect the battery if the phone was charging one night.. I remember seeing a forum on here that the phone might be still on charging mode or something.

Hi,
I have the same problem, the only sign of life is a red flashing led when I try to charge it up.
My lg g2 (D802) did get water damaged tho, however I don't think it has been damaged that bad. When I found it in the watery environment it still worked, but it was quite warm. First hour or so I put in in a towel, because I wasnt home. When I got home I discovered it was dead. Then I put it in rice for two days, but now this problem occurred.
I reconnected the battery (twice) but it didnt change a thing, and now it still won't boot up...
Hopefully someone can help me (or sees this at all),
Thanks in advance
I have the same problem with my G2. I changed the motherboard after it got water damage but nothing else changed. what should i do?
Solution for blinking red error
Hello Guys,
I have the same problem like you others. 8 times red blinks, phone won't charge, PC won't recognize it, dead at all. But I found the solution. There is a short circuit on the moterboard. That can be LCD, digitizer, buttons or anything other. I have unpluged digitizer connector and BOoM!, connected it to charger and turn on with power button. So you guys can test what's making problem on your MB, it can be anythinhg. I hope that will help to someone.
Sorry for bad English.
same thing here
I have an LG G2 that I recently replaced the batter (ordered from ebay). After the install, the phone just blinks the red indicator light. When I hold the power button, it blinks 8 times, pauses then starts over again blinking 8 times and pausing. Please help.

I have the exact same problem. recently bought a new battery, because my original one is increasing in size (very strange) and decreasing in power.
When i put in the new battery the phone doesnt work if i try to turn it on. When i connect the battery to the charger its just the blinking red light...

I'm having the exact same problem...working ls980 phone using to restore my D801 motherboard....but have no power.
When I plug the ls980 board back in it works again. Last time my D801 board red led blinked 2x but wouldn't startup with its own battery. How did you fix it?
It is the battery. either the cable is ripped or the battery is at 0 volts I've just tested this on my LS980 using my analyzer to fully charge a battery externally to 100% made it work fine, please check the battery cable its very thin and very easy to rip without knowing it. (I work at a battery store) Hope this helps some of you!
A solution for 8 Red blinks:
If you have 8 Red blinks when you change the screen the Solution is:
The two metal joints from two small boards (besides volume and power button) that connect to the motherboard they should be completely attached to the connector.
Dad's S4 i9500 suddenly died.
Won't turn on at all. No recovery mode, nothing.
No damage, phone is immaculate.
Was not dropped, nothing.
Phone will not charge and screen that shows charge when charging shows nothing.
Any ideas, anyone?

Double check your power supply and your usb cable. Probably the battery is totally empty and will not been charged...
I keep a few spare batteries on me that are always fully charged. We have tried a couple of those in Dad's phone, then put them in my phone to check they had charge. They had 100% charge.
The phone was still 100% dead with the 100% charge batteries in them.
I have replaced the charging port ribbon last night in case this was causing a short.
The new ribbon made no difference; still 100% dead. Nothing at all. No sign of life at all.
I'm thinking the on/off button or the power IC.
Of course it may be something else.
Your thoughts?
Thanks
It can be the power button has gone faulty it happened to me before try smacking the power button couple of times to see if it makes any difference i pushed mine against a desk a couple of times and it worked after that i installed a shake lock app so i don't need to press the power button anymore unless i need to turn on/off the device.

I put a ohm meter across the on/ off switch this evening.
I get infinite resistance when it is not pressed, and finite/ no resistance when button is pushed.
So the switch is working perfectly and it's definitely not the on/off switch.
Any other ideas?
guess your motherboard is x_x then
Yes seems to be the board.
What's the best way to work out what's wrong with it/ get it fixed.
Anyone know the most likely cause/ who does, or how to do such trouble shooting analysis.
Hey.
I've tried to fix my phone screen's digitizer (first idea was to unplug the screen and plug it back in, which kinda worked). The phone worked fine while disassembled and I did a stupid thing - I turned it off by disconnecting the battery, as the power button was not working while disassembled. After I put it back together it did not turn on anymore (disassembling it again does not help). The notification LED is flashing while I'm holding the power button, it also starts flashing when I plug in the charger.
What could be the issue here?
EDIT: I figured out the issue - I broke off a tiny component on the motherboard while putting it back together. Took me a while.
How is the phone now? Did you replace the motherboard or lcd display? Did you repaired? Is the phone fixed?

I have soldered on a new capacitor (one that I broke off) and now it is working fine. I still have to replace the display though.
Can you take a picture where is the component located
Can you take a picture or link where is the broken component located?

Hi all,
What do you think, what could be dead in my phone?
Phone was working perfectly, when I was reading some stuff using Chrome it stopped working [freeze], I pressed power button for few seconds and phone rebooted properly, I could use it for another about 20 minutes and then I got another freeze, at that moment I was not even able to restart phone with power button, when battery level was 0% phone came off, I charged it again and was able to run it for another about 15 minutes, I even managed to go to TWRP and saved a backup,:good:
Finally in TWRP mode my phone got a freeze and after that I am not able to do anything (it was freezed for a few hours and was not responding for power button at all) , phone is completely dead since then, I can not charge it, any keys combination is not working at all,
I guess it will be battery or main board issue but what do you think? I opened a rear cover, disassembled battery but physically everything looks fine,
Thanks for any ideas,
Cheers
its nearly impossible to tell, the two things you have mentioned (Mainboard & battery) are the two most likely to have broken....
Sounds like your phone is bricked unfortunately - you could try taking it to a repair shop for a 2nd opinion
