Does the screen go white right away or after boot?

The screen turns white about 2 seconds after power is applied. later, turning it on and off does not change anything

yes i like this but how to???
It s really really easy.At first i thinked to change the smd leds like someone of this forum in htc section...But then when i opened the phone to look at the led,i ve noticed that under those touch buttons there are some stripes of like insulating tape to diffuse the light.All I had to do was to detach those stripes,and attach the new coloured ones.I used insulating tape,the worst it's better because is more trasparent and so you have best lightning.And then you have reversible coloured buttons.
its awesome...i got a lot of insulating tape floating around here... i ll try that mod, thank you

Sorry, it looks like your screen died.
If you can't get it repaired or swapped under warranty, take it apart and try reseating the display connector.
I don't really think that that's the problem, but it's worth a try.
Replacement screens on the market cost about what a discount Nook costs.

Yarvik smp50 broken gray screen.

Hello,
I got a problem since yarvik was gone bankrupt, my screen is gray. I think in the inside something is loose since I can hear something when I shake it. Now I want to know if this is solvable. There are sounds hearable when turning on. The screen is always gray no other display. So can I crack my yarvik ingenia horizon smp50-201 open? There are screws in it. I tried to open it nothing worked. BTW the screen is cracked too.

Enter download mode and recovery. If you only see part of the screen in both modes, the screen needs to be replaced. If not seen in either mode the GPU on the motherboard is the culprit and needs to be repaired.

Nothing on display, after attempting to replace screen

My I9505 screen was broken, so I attempted to replace the screen. After doing so, I noticed that the pins (on motherboard) to which the display cable connects too looked to be damaged.
After everything was connected etc. I then turned my phone on. And although sound emerged and lights lit up, nothing appeared on the screen.
(I'm assuming the problem is with the pins described above)
A picture of the motherboard is below.

Is there anything that can be done to repair the motherboard, so images will be displayed on the screen. Without paying for a new motherboard?
P.S I have tested the new replacement screen on another I9505 and it worked perfectly ( so the fault is definitely with my i9505's hardware)
