Samsung LE32R748BD - possible screen fault

[noledud]

HI all

I got this tv from someone who told me the screen was good but cant remember the fault, she said they tried replacing something but couldnt tell me what

do you think the below is a screen fault or incorrect main etc ?

the screen comes up for a second with the picture below and goes round in a loop

Doubt screen is bad.
Looks like a main board fault.
If it had bad caps you should reset eeprom (pins 5-6)

I'm not sure but the info is probably elsewhere on the 'net, I think there is a Samsung service bulletin about replacing/resetting EEPROM after capacitor replacement.
