    LG 43LH510V Backlight problem
    by unimatrix93
    Hello everyone,

    I'm trying to fix a small LG TV with wierd issue.

    So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
    Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
    The BL turns on, the tester shows around 80V. So the led strips are okay it seems.

    Now I started to suspect the BL driver IC which is a MP3378.
    I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

    Assistance with identifying replacement caps on ASUS P5VDZ-MX
    by crosswinds
    Hello,

    So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
    Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
    Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess

    Its a ASUS P5VDZ-MX board.

    I would really appreciate some assistance on what the best replacement caps would be for these:

    Panasonic(M)...
