Hello.
I have 29inch LG CRT TV,And Yesterday,Whenever I connect AC power cord to power outlet without switch on, I heard a sound like white noise, And When I switched on this CRT TV, It sometime displayed correctly But usually It won't last more than 20 minute and The screen begin to dark and It finally did not display at all for hours..
Today,I dismantled its plastic case and discharged the biggest capacitor(400wv 470uf) which still holds 250 voltage,and I finally detached PCB from cathode-ray tube.
I measured ESR value of most of caps in PCB with MESR-100 and I found that KME(25v...04-17-2024, 07:11 AM -
Hello, I have a bricked Eluktro laptop, can't seem to find a bios dump. I would like to have the ME cleaned please. The bios download from the Clevo repo has a file with a ".12" extension that is the same file size as the original bios but it is "configured" as opposed to "initialized" according to ME analyzer. I tried it and the laptop still did not boot.
Can anyone help me clean ME or repair this bios please? I attached both files....05-01-2024, 03:03 PM -

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...Today, 03:25 AM -
Hello,
I have an HP 14-dq0055dx laptop here that came in for boot looping. It was previously taken to another shop and they tried flashing a BIOS firmware to the chip, so I cannot take an original dump. For a second or two, a message will come up on the screen that says:
This loop will go on for as long as you like. I let it run for about 12 hours and came in the following morning and it's still looping.

Hello everyone,
This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.
My patient is an A2338 Macbook Pro M1 (late 2020).
It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...04-22-2024, 06:45 AM

Dear forum,
I'm stuck with this old TV unit.
PSU: 17PW04-1
MB: 17MB62-1
Symptoms:
- Blue LED constantly blinking when connected to AC.
- Only sigh of life is beeping when touching the capactive buttons on the front.
Diagnostics so far:
Checked the PSU output voltages:
12V present
5V present altought its only around 4.2V
3V is present measured 3.4V.
I check TP 202 which is for the short circuit protection: 0.606V on diode mode
Since I met with some vestel models before with similiar symptoms...Today, 03:18 AM -
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...Yesterday, 12:18 PM -
