Re: LG 42LD750N * Vertical lines flicker + screen flickers - VIDEO
Update.
Worked good for a while, same issue when it warmed up. Think the problem is the t-con board as it reacts when tapped on. Already ordered another one as i found one cheap.
Pressing along the sides of tv or touching lvds cable shows no reaction.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Grundig 49 VLE 6620 BP Led *Backlight blinking
Backlight blinks on-off constantly.
All Caps look ok.
PSU measured:
CN2 13 BL - 3.3
CN2 15 - 19VDC
CN2 1-2 = 27VAC
CN2 3-4 = 67VAC
CN2 7-8 = 75VAC
Some of those values dont make reference...

Re: Help with LG 47LV550W troubleshooting
Read about how to enable test pattern. But what kind of tools or wires should one use when making the jumper connections? Everything is so small....

Re: Help with LG 47LV550W troubleshooting
When cables from mainboard to t-con is removed (picture) the lines disapear and screen is completly empty/dark.
The T-Con board is behind the stand and need more work to get to. Can do this but if you guys are certain that its a bad panel i may as well scrap this one.
Any more toughts or things i should try?...Last edited by busigkille; 11-12-2017, 09:47 AM.
