    Lenovo Ideapad Gaming 3 15IMH05 - BIOS REQUEST
    by mrgumshot
    Hi all,

    I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
    So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.

    After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.

    I hope someone can help me out. Attached is my [B]ORIGINAL...

    Panasonic TH-55FX600 - No standby LED
    by Xrious
    Got a TH-55FX600 that is showing no signs of life.

    Outputs from the P board look good, but no 12V on the A board.

    Very similar to [URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-tvs-and-video-sources/110001-panasonic-tx-65fx623e-identidy-ic[/URL] but where Tibd has 3.3v on the EN pin I have nothing, no voltage at all.

    Looking at the diagram for the IC I can see the enable is W_OPCTRL9, but I can't find a source for this, can anyone help please?

    Hello, recently I encontered an issue with my BIOS, it just corrupted out of nothing, it all happened after I just shutdown my laptop.
