LG-32CS460

Hi folks,

Have one with LED back-light running but no OSG nor picture.

Checked T/con fuse - OK.

Next bit is interesting, as got a T/con from 'The Flea' where picture was visible but solarised,

Tried original T/con - Picture but now solarised.

Suspect main board the problem as T/con has no AS15 chip.

Sad thing was that cust got it new from his daughter, but took him 2 years to bother try turn it on.


Later - Found and downloaded firmware from LG - Installed - No difference, so guess main board or screen itself.

Hi,
Possibly the LVDS cable, worth a check\clean.

Hi John, and thanks,

Will give a try as seems odd that 2 T-cons without AS15 chips could have the same problem.

When I first had a look, where there was sound but no picture, the Blue LED on the T-con flashed then went out, but with the second one, it stayed on all the time giving a solarised picture, and on re-fitting the original got exactly the same result.

Seems the lead could be the problem, even on a set that's never been turned on, just stored for 2 years 'till customer got 'A Round Tuit' - Thanks again - Chris.

Thanks again - Chris.

Later - Was an LVDS lead problem where flat flexi didn't go far enough through the plug housing to make a good contact with T-con socket - Only the very ends had socket imprints. Managed to push the flexi through the plug housing, but difficult as seems to be glued in and the plug housing doesn't seem to come apart - Could have just removed the plug and pushed in the flexi, as a fair bit has exposed contacts, but unsure whether the plug housing does anything useful
