Hi All, I have an LG 50PK550 with the EAX61392501/10 EAY60968801 power supply board. When I turn it on it clicks and shuts off immediately, I have unpluged the power wires to to Zsus and Ysus board and it does the same thing. I have read up and replaced IC301 & d304 and checked the R927 R929 and all 3 fuses on the board and all appear ok. Still does the same, shuts off immediately with or without the z & ysus board hooked up. Any help would be appreciated. Thx

Check for cold solder on the underside of the board, pretty common. -

Have a look at the components in this repair kit and check the parts on your power supply.

This is a weird one, as mentioned below I checked and replaced the below components and put the the board back in and it did the exact same thing. As suggested I removed the board, reinspected and checked the complete board for cold solder joints and none were found. The board was a little dusty (I have seen much much worse) so I gave it a good dusting with a paint and tooth brush and put the board back in. Now the TV stays on now without issues, I have given it two tests for over 8 hours each. Is it possible there was some dust shorting out something on the board ??

I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and... -
Hello everybody!
Have in work A1706 820-00239 model. Originally no power, shorted PPBUS_G3H because of corroded C6403, C6404. Some water damage around this components, but nothing major.

Sometimes the laptop shuts off immediately when some action with Type-C ports performed (charger disconnected or USB device inserted/disconnected). I checked Type-C port flexes, they are okay, but I cleaned them anyway. I can't see any signs of liquid...11-20-2024, 08:14 AM -
Hi. I have a pre-owned Dell Inspiron 15 7567. It worked fine
During the first 3 days of owning it until Dell Update software popped a notification about a latest Bios version 1.15.0 and latest Intel ME Software update of which I updated. It rebooted and firstly, Upgraded Bios from version 1.8.1 to 1.15.0 then it started upgrading Intel ME firmware. After that update, my laptop shuts down without notice (Like thermal shutdown)
I checked Thermal Paste on the processor and the Graphics Chip and it was dry. Replacing thermal paste has not helped me.
Now I've noticed that laptop...
