Re: LG 42LG3000 LCD TV Fault Finding.

Nothing obvious that I can see. Looked at the white surface mounted fuse and looks in one piece. Continuity confirmed.

Here's a picture of what it looks like - should be clear enough to make out everything. Clicking it Zooms in.

Here is a YT Video of what I get without plugging in the Slave Invertor Board -

Much much better view of the whole board - held still by glass table above it - no hand shake.

I'm just taking a look at the condition of the 'sync' cable at the moment... [EDIT] Looks OK.

Here is a question.

Can I swap sides with the Master and Slave to see if the Lamps OK on the left hand side?

--edit
Nope plugs are slightly different. Still looking for ways to test the components on the Slave board then.

Hye. i need a little technical support, i a have an Lg 42Lg3000-ZA and i have a white image with sound. I measure voltage from connector 1-4pins and i have a negative voltage -12Vcc, and i guess actually a need +12Vcc regulated.
do you know what voltage are on the rest of pins from 5 to 26?? I can find a scheme or diagram of this module which is T370XW02-VC/ 37T03-C00

So, yesterday i was to LG service. I have a 42LG3000 television, with this simptoms white screen but good sound. Actually i try to change T-con Module, i bought a new one, i replace all condensators, finally from service sad me this: YOUR DISPLAY IS DEAD, ACTUALLY , the matrix from this is broken, its necessary to buy a new one, but may be you need to buy a new tv.
So if you this problem, don't try to change some parts from inside, because 99% the display is broken............
Good Luck.
