Re: LG W2242S with burnt out inverter transformer

Hi sorry for the unreliable data am new to this and I still have a lot to learn as you can tell when I tested the rectifier diodes I had the power supply plugged into the board, so there was power running through the board but I couldn't fully power the board on as it was unresponsive is that still bad to do with the meter or is it just as long as the board isn't fully powered on, I changed the LAF0001 chip and now the monitor seems to be working fine at the moment but it hasn't been on that long so fingers crossed.

Re: LG W2242S with burnt out inverter transformer

rectifier diodes are bouncing around from .1 to .5 Ohms when power is on I have no standby light, and the 450v cap when the board is on dose not hold more than 100v[FONT="Comic Sans MS"][/FONT]

I was thinking the other transformer because a few weeks before it died it was making a hissing sound then the clicking started and then one day the picture just slowly faded and the monitor just died I will check the power MOSFETS now is there any thing else you would recommend checking and thanks for the help.

hi I tested the rectifier diodes again to double check they are bouncing around from .1 to .5

Re: LG W2242S with burnt out inverter transformer

[FONT="Comic Sans MS"]Hi I have a lg w2242s and of course it's dead I have replaced all the caps with panasonic ones and the 470v at 100uf with a rubycon one and replaced the EEL22D transformer with the one from the link on this post but still nothing but my smps transformer in making a very loud clicking sound, the monitor powers on but not fully I was wondering if a smps transformer from a lg W1943SB would work or if anyone knows were I could get a replacement thanks.
