Hi people,i acquired a 42lg3000 that has a temperamental fault,i was told that it sometimes come on no problem,sometimes wont fire up the backlight.i got the tv home,tried to turn it on,only got the flashing red led,then turned to blue but no backlight.i opened tv,done some quick tests found that the inverters wernt getting the 24v? done some probing on the main board for vlts when i turned tv on again,24v came to backligh-light on no problem,so i thought it must have been a bad cabled running from the main board,turned it off and on a few times,all seemed well.thought i was in luck,just a bad connection from the wire i fixed with the probe from the multi meter.put back back on tv,pressed on-red led flases till blue light but no backlight!doesnt seem to be sound connected via hdmi,opened tv up tv done some tests,no 24v to inverter?i unplugged one inverter,turned on ob no backlight but i caould hear the sound?
plugged the inverter wires back in.tv came on with all working.off and on a few time tv would flash till blue light-no back light or sound.
would a faulty inverter cause the tv to turn on but with no sound from the hdmi input?
its a hit or a miss if it comes on,but when its on,it runs fine,no problems.
where do i start?all caps look ok, any heads up to where to begin?
thanks for reading
