Title: LG M227WD-PZ seems dead - any ideas or anyone have the service manual?
Post by: markie76 on June 19, 2010,20:59:29

Hi GUys,

My LG M227WD-PZ 22" LCD TV seems dead.

The blue LED on the front doesn't illuminate.

I have opened it up and the power board (AIP-0156) seems to be putting out the 5.1v & 15v ok.

The digital audio output has the red light present in the socket

But there are no other signs of life :(

Can anyone advise

OR

Does anyone have the service/repair manual for this model?

Thanks,

Mark.

hello again, we have found the 1.2v is down to ic1100 being sluggish, check for a high from 1c100, the most convenient place to check is r236, its a zero ohm, it is placed at the top of the board near ic301, if low all the time irrespective of switching on and off this 1.2 may have ripple on it
