Got my Head unit from Pumpkin in Jun 2015. Had no major problems with it until December 2015. Drove for 4 hours with the head unit running TomTom with no problems. Went to use the car the next day and the headunit's screen was just black, the backlight was lit up and all features still worked. Poweramp would load up and start playing music off the SD card and I can get the radio to work. I can even change the station using the touchscreen.
This leads me to this it's the LCD that gone faulty. Just wondered if anyone has any idea I could try to fix it.
Been 3 months without the head unit now, so just wondered if anyone can think of something to check on the unit, or if anyone knows what screen it uses?
I've tried checking the connections for the board and the screen, but couldn't see any problems.
Specs of the unit are:
800x600
RK3066
Ram: 1GB
CPU: armv7 1.6GHz (x2)
MCU: MTCB-KLD2-V2.50
KLD
Thanks

Had the same problem with mine, this may sound stupid but have you tried the reset button. I pushed the reset on mine and the screen worked again when it rebooted, it has done this twice where I would lose the display but all else would work. I have reflased the rom and have not had the problem since.
the reset is a small hole on the front of the unit.

Hey Paul,
Have given it a go a few times. Did you press it whilst it was on? and for how long?
Also, what rom did you put on after?
Cheers!

Pressed it when it was on, the unit should shut down and then restart. Rom I got from autopumpkin.com it's there stock rooted rom android 4.4.4 duel core

Gave it another go but no luck. Thank for the suggestion though.
Currently awaiting (Since Jan) for a replacement screen from pumpkin. They have not been helpful.
Might give it a go at flashing the pumpkin rom without the screen on
Hi, Have a similar problem I have a Pumpin 10 4gb ram 32 rom. The screen is blank but the backlight work. I have no sound and nothing works, however, if I turn it off and on again every now and again I get something like Pumpkin 10 for a split second then the blank screen.
I tried the reset button a few times but nothing
Hi there,
im not sure if this is the right chapter for this, but i have a hardware issue.
I've bought an 8inch vw android radio from aliexpress. according to the mainboard it is an DU8015-m-1v5
The problem is in the display, when it's could outside (which is around 6 degrees centigrade or lower) the display turns to white where it should be nice and black. Once the temperature gets higher the display gets quite normal again.
Now i have had this issue since day 2 (after arrival when i built in the radio) and made reclamations to the seller, which told me they would send me a new display which would fix the problem. I asked them to send me a complete new headunit, but they wouldnt. this should be an easy fix.
Now afther whining and going on about it at the seller i have received the wrong display, the original has 2 flat cables and a power connector... the seller tells me to replace it anyway.
I guess this will brick my device immediately (or at least blow some fuses) ??
here's a link to all photos of both displays https://goo.gl/photos/vs1GHJKBnjtnf6Eq5
any technicians who can help me out and tell me if i'm right or wrong ??
Hey everyone,
I had an issue with my previous unit where the screen went dark and nothing would work. Joying sent me a new base unit. I got the new unit hooked up (which isn't the same model or something because it is missing 2 video out ports) and upgraded to 6.0.1. Everything worked fine for about a day and a half and now the touch screen doesn't respond. I can use a mouse and keyboard to navigate the unit but the touch screen doesn't register any touches. I have reflashed the 6.0.1 update as well as done a factory reset. Any other ideas? I really hate to have to end up shipping it back to joying as the process takes forever and now I have to pay to ship 2 units back plus possibly the screen. It is really frustrating. Is the quality usually this bad?
If its been in the vehicle the LCD/digitizer connector might have been vibrated loose. Have you tried unhooking both sides of the cable from the board and screen, checked for damage on either of the cable ends and both connectors and reseated everything firmly?
please let us know what you guys end up doing. My digitizer went bad also.
Can anyone help me. I purchased a 12.8 tesla style unit. MCUVer says RL7Ac_KLD9M_dsp-F031 -V1.01.009CYPR. Everything was working fine until one day i got in the car and nothing played from the speakers. Unit was working fine. Then The next day the screen went black. Now if the key is in Acc the unit works fine, plays music but the second i switch key to on the image on the screen gets frozen and then fades away. I conacted the company and they want me to send the unit back for repair but i checked prices and its $100-200 to ship back. thats 30 to 60% of what i paid for the unit. Should I just cut my loses and go with a different brand?
Hi all,
I'm having issues with an Android head unit I installed a couple of years bought from carpar.nl. It's an Avison RNS510 (8227L) replacing my Skoda Fabia Swing stereo.
The other day the display gave up the ghost and started showing flickering white lines. I've checked connections at the back and wiped the unit with no success. Any ideas? Cheers.
