Re: inverter problem in LG 1934S LCD flatron

Thanks guys for pointing me to all that useful stuff! I think I'll make much better progress when I get going this time!

For reference and any further questions I ask, some photos and info:

Also the ICs, IC501 is an OZ9938GN
U501 and U502 are both a P6006HV

I have the photos in a much larger resolution but I though 800px wide would be enough, let me know if it's not

Thanks again all, great replies!!...

Re: inverter problem in LG 1934S LCD flatron

Hi guys, much searching and some testing and I'm a bit stuck. I have this monitor and the backlight goes out after a 2 seconds.

Here's what I've done so far:

I think I eliminated a bad CCFL by unplugging one at a time and turning it on. Same problem.

I've followed this flow chart in the service diagram and it all seems to check out.



I'm not sure if my results are any good though as I've not desoldered anything from the board, and I'm getting a 1.7ish volts reverse voltage...
