Hi,

Note power supply includes inverter. Would think that if caps are not bulging, it might be a duff CCFL issue, but unsure as to go about testing them as guess they're all connected in parallel so can't check individual tubes without dismantling screen, maybe - Good Luck - Chris.

Notice several P/I boards for your model on Ebay.

i tested the inverter with an other ccfl that i have out of the tv and the symptom is the same.

i changed all the caps and did not solve the isue.

do not know what to check more?

Hi,

Guess if you've checked with another screen, as you seem to have, why not replace the Power/Inverter, as they're cheap on Ebay at this moment - Chris.

shopyd:
yes this is what i will do at the last option

i see that aliexpress sell this boards for 40$ including shipping (used)

i wonder if to buy them or look for new ones?
