Hi everyone,
I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.
The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.
After checking the basics I did the following:[LIST][*]I measured all voltages and as expected the only active supply is the 3.5V standby....

The treadmill was working fine, one day the belt snapped and after checking the unit I also noticed that the display is now showing the Controller comm error. So I opened it up and the treadmill had two boards. One is a power supply board and the other is the motor controller. I noticed there was a mouse nest, so I took power supply board out, cleaned it up, replaced the big capacitor and that did nothing. Then I took apart the motor controller and cleaned that up, and when I plugged it in, it started right up. I thought I fixed it. But when the belt arrived, I installed it and tried to power...11-04-2024, 01:32 PM

I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard...11-03-2024, 06:58 AM -

TV won’t turn on there is no power light or standby light lit up .
The person I got the tv from said someone told her it’s either a bad board or a bad screen .
How do I tell what I need to replace like a power supply board or main board or the screen itself is bad ?11-03-2024, 10:46 AM -
Had someone drop off a laptop in which they were upgrading the ram but forgot to unplug the battery.
Looks like the ram RFI shield shorted a rail going to or coming from a Silergy IC which blasted a component off the board. I'm going to assume it was a cap but really have no way to know for sure since this board schematic doesn't appear to be in the wild yet.
I'm trying to identify the IC model now but it doesn't appear to match any of the Silergy codes from [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/80630-ic-marking-codes-and-datasheets[/url]...11-01-2024, 12:50 PM -

Removed the two chips from the broken lcd at 350C and 40 air by properly protecting rest of the area with copper and kapton tape.
Did the same with the new replacement panel.
Reballed the pulled chips and installed on the new lcd panel at 250C and 40 air
I have done few ones before without issue.
The new panel was working before I transplanted the chips. Now the computer turns on and boots but no image/ backlight.

I received this tv stuck in a boot loop and was able to get it working after letting it sit and reboot several times. Whenever I try do things in the settings it will crash back to the main screen, lock up, or reboot itself. I tried doing a Reset on it and after it rebooted nothing was changed. The Google account used was still present, and the downloaded apps were all still there. I can sometimes get further into settings such as setting up my wifi, not most times it will crash and reboot. I even manually removed the Google account and it CAME BACK after rebooting the tv. Before it rebooted one...10-05-2024, 11:29 AM

I'm trying to fix up this HP laptop with no power problem.
Power led does show white led as I plug in the charger but it doesnt react to the power key.
I connected it to my PSU and as I turn on the PSU, the board takes 30mA for a few seconds then it goes down to 5mA. Connecting the battery doesn't change the current only turn the white led to orange.
I checked all the coil on the motherboard and I found 1.3V and 5V but no other power rail were present.
Also, I checked on the bios IC (XMC QH128ahig) and it missing VCC.

Hello! I have exchanged the mainboard TNPH0993 in my TV Panasonic TX-L42ET5E (E like Europe) for the same board which comes from TV TX-L42ET5B (B like Britain). The TV works properly, but in menu is missing the possibility to set the language and the region of use. I tried to set it in the service menu, but there it isn't possible either. In the end I upgraded firmware on the newest version for Europe models and expected it to help, but it didn't. The two items in the menu are still missing. So my question is: " How can I set this board from Britain TV model to the Europe model?" I think...11-01-2024, 07:35 AM
