Hello all
A friend brought me this TV to see if I could fix it.
TV has the classic sound but no picture issue that I am pretty sure is caused by a few bad ccfl bulbs which seems to be a common issue for this model of TV.
I just wanted to get some opinions from a few more experienced people.
Symptoms: After pressing the power button the green power light comes on and about 3sec later the backlights light up (with a buzzing noise) then go right back out.
I have read that disconnecting the K8L connector should cause the backlights to stay on for a longer period of time, but when I tried it the only change was that I got the backlight flash immediately after pressing the power button instead of the 3sec delay that happens when K8L is connected.
Tests done so far: checked fuses on both inverter boards, checked voltages and they were ok.
A few times the TV would stay on (with a buzzing noise) and what looks like 3 darker lines going across the TV (bad ccfls I'm assuming)
What is causing the TV to work sometimes and not most of the other times?
can I "hot wire" the TV to run with a few bad bulbs or would that be dangerous?
thanks
