TCL LE50FHDE3010 flasing

[johnvpr]

Hi there,

I have a TCL LE50FHDE3010, I can hear audio, but the screen is kind of flashing:
Watch Video

I Changed PSU, T-Con,Motherboad but it did not fixed the issue.

At this point what could I check?
- Change the Led Driver board(L500H1-2EA)?
- It might e a LCD issue?

Thanks

John

So just a dark blue glowing screen without any images on the screen?
Try having ribbon cables between the T-CON and the LCD panel connected one at a time to see what you will get on the screen.

Good Call,

budm, you are awesome!!!

with only the left cable I see half of the screen
with only the right cable I see all black
with both, I see the dark blue glowing screen

by inverting the ribbons, i have the same results

Doctor, it is something serious?

The Tcon is the V500HJ1-CE6

Thank you so much!

Re: TCL LE50FHDE3010 flasing

You have bad panel, the bad half (the one with the right side cable) probably drags down the Voltages on the T-CON when it is connected so it kills the whole screen when both ribbons are connected. There are many SMD caps on the bad half of the screen tab bonding board that you can check for shorts or leakage resistance, it can also be the line driver ICs on the flexible circuit between the LCD glass panel and the tab bonding board.

The bonding board is the v500hk1-xls5, it is any way to change it?

I found a seller on china, but wondering if it not possible:

I wouldn't think so since you have the symptons of a bad panel and not a bad Tcon.
