Belinea 102035W - doesn't display properly

[Folxs]

Hi, I got dead Belinea 102035W display, with no backlight.
1. I replaced BD9883F chip and backlight started to work.
But, on the display are strange strips, I'm afraid that maybe EEPROM is bad or something.
All caps look good, but I didn't test them.

Here are some photos of totally black display without backligt (off) and some random stuff when I try to turn it on. Also photo of SOP8 EEPROM 24xx chip - maybe someone have EEPROM dump?

What could be wrong? Any ideas?

Bad LCD panel.

What do You mean? LCD isn't cracked or dropped. Or do You mean broken LCD processing PCB? If PCB, then - Yes I know that, it is broken. But what are guesses?
Trying to measure caps, or my hypothesis is bad EEPROM or some caps maybe.

I found that photos on forum:

Bad tab bonds on panel

Tab bonds? Sorry but my English isn't very good. Can You explain in few simple words what is that? I should understand what it is in my language
And maybe how to fix it.
Thanks!

Ok I Got it. Ripped cable inside the LCD itself

Its the film that connects from the circuit board to the liquid display panel is starting to separate.

Ok, if not bonds inside LCD - then what could be bad on LCD pannel? EEPROM 24xx? Caps? Something else?

there is nothing much you can do to actually fix this, besides replacing the panel.

Re: Belinea 102035W - doesn't display properly

You mean panel is LCD front panel (display)? or panel = PCB? In my language panel can mean LCD itself or PCB so that confuses me :P

So You think that bonds are ripped? Not EEPROM / PCB inside broken?
I think that guy who opened whole construction could rip something off

The panel (screen) is no good Ekran nie jest dobre
You can't rip anything of without taking the screen apart

Yes, I meant the LCD display.

Ok I got it. Sorry about that whole confusion.
I ment that I think, that during opening that monitor, guy in the shop could destroy LCD because he wasn't carefull enough

Depends what he did to the monitor. If he had the LCD display out, or the LCD apart on top of being taken out, then well... very certainly everything is possible.
