Re: LG55UK6950PLB backlight but no picture
Lotas, thanks the schematics!!!
Based on them I could disable the IC800 / i2111.
( removed the resistors before and after this IC. R801, R820 )
It seems, that I still have a short on HAVDD line. I removed the big cap from this line ( C806 ), but the short is still there.
Do you have any additional tip for the repair?Leave a comment:

Additional info:
If I disconnect the left ribbon I can measure VCC, VDD on the right side, but IC800 is getting very hot. It's an i-2111 J824 IC. What it does? Has anybody info about it?...Leave a comment:

Re: LG55UK6950PLB backlight but no picture
Hi! How could you make it work? I’ve got a TV with the following issue:
If I remove left cable, I can measure VCC, VDD etc voltages on the right LCD board. If I disconnect right cable, and only left cable is connected, I can not measure any voltage on the left cable.
More interesting, I tried the “tape fix”. I covered CK lines One by One and all together too, but No changes. Do you have any tip for furthet fixes?Leave a comment:
