hello,
i try to repair a Dell 20'' 2007Fpb
At the beginning, the monitor green led blink.
After searching, i found and change :
- 3 caps 220uF/25V ont the inverter board
- 1 caps 220uF/25 ont the USB board
- 1 caps 180uF/450V on the main powerboard
- 2 caps 100uF/25V on the logic board
Now the montor start and i can view the autotest on the screen but there is an another problem :
- VGA : grey screen if signal is applied
- RCA composite signal : not detected
- DVI : OK
No problem with the OSD and menu function. No problem with light and contrast.
If y try the pip function when a vga signal is applied, on the two box on the screen, the left box (vga) is pink.
it seem that all analogic signal applied on this monitor is KO but i can't explain why DVI is ok (so numeric signal)
GPU is FLI5961H-LF
Anyone have an idea of the problem ? GPU is dead ?
Thank you
Emmanuel
