Nokia E50 Display Solution Wanted


Hello Everyone
I have a Nokia E50 RM-170 with display issue. The problem is that its flashing (going white/blank every second and coming) continously, everything else is working perfectly
i have done everything i could but nothing helped, following are the things that i have done so far;

1. Factory setting with JAF
2. Flashed version 6.41
3. Flashed with latest 7.36 mcu + ppm
4. reflow emif ic's around display connector
5. checked display connector reballed emif ic's around display jack
6. checked LCD connector n flex cable
7. Applied heat to the PCB without removing metal shields

one thing i cant do is check LCD on other set or check other LCD on my E50 PCB even knowing 5300, 6233, 6234, 7370 etc are compatibles due to unavailability

im also very concerned whether this kind of problem is a known issue 'cause i have googled around so much but find nothing like this anywhere
if it is a known issue even in other nokia models than what is the cause (hardware or software) any clues are welcome,
Please suggest something..... im very upset n becoming hopeless
New LCD is very expensive, almost to the price of a used one

I cant understand yet whether its a hardware fault or a software error

Please Help
Thanks

Note: I have recorded a small mp4 video of the current condition 161k but unfortunately i cant upload it for some reason even after zipping it
