    Changing Bios boot image? -Y11B
    by Azy
    This might not be a very popular request, but for the past few weeks I've been looking into how i can change the bios boot image on my Haier Y11b 2in1. From what I've learned, the image is broken down into a hex pattern which is supposed to be pretty difficult to find in the bios file and replace with a custom one.
    The laptop that im planning on making this change was provided by the government and therefore shows the governments ugly logos and all on the boot screen rather than the manufacturers (Haier) logo which has got pretty annoying over the years. If someone can help me with this,...

    Is it no harm to replace with capacitor without ripple current rating?
    by chth96
    When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.

    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.

    MTC Mtc4k58s21 58" TV Hk.T.Rt2851P838
    by Bholu
    Hello friends, I have MTC 58' TV which has stand by position. I thought the software was corrupt. I have downloaded the software from the internet but the data is not matching. The format window is opening from the TV software but none of the buttons on the remote or TV are working. Why? Can I edit this software with a hex editor? Is there any guide to edit this? Or does anyone have access to this software? Thank you very much for your help.

    HP Omen 15-dh0052nf power-on & bios password
    by Nopslide
    Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

    My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

    Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

    Help me find the short circuit on this WORKING Nvidia GTX1650
    by aaronkatrini
    Hi all,

    Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

    Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

    I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...
