LG M227WD

(1/3) > >>

kumarj:
Hi all,
        I have a friends tv which has gone faulty. It is a LG M227WD which has the same fault that was posted a couple of years ago by Markie76. Basically there is no life at all but the optical at the back which illuminates but at varying brightness. I have checked the psu and it does show the two 15v and 5v at the connector. There are no bulges from the caps or any burnt components. I don't have any other test equiptment apart from a multimeter. Is there anybody who can help at pointing me in the right direction or is there anything else that I can try?

Regards,

Jet

If you get one one of these that wont power up but the 12 and 5v lines are present from psu check the 1.2v reg (ic1100). this can be intermittent.we have had it a lot!

kumarj:
Thanks for the reply Tony I really appreciate your help but I just cannot find IC1100. I can find it in the service manual but this board is M22/237WDP-PZL   LD93C. The service manual I have got is for the LD84G chassis. I was about to screw the tv back together and return it to my mate until I read your reply so if you can or anyone else can shed any more light I would be very grateful.

Cheers,

Jet

tv tony:
what are the letters after the model number, lg tend to fit different versions in their sets, thats definitely the right ic number on the version we do.

tv tony:
hello, now i know what chassis is fitted the normal cause is ic1105, opto lit and standby only, (12v reg)
