Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard.... -

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.
After replacing this capacitors the laptop came back to work, I reinstalled MacOS and had no issues until I started to test Type-C ports. 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 discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.
General test conditions:
- Tested with Core i5 6500 and Core I7 6700K - no difference
- Default BIOS settings, but tried also altering several memory setting - does not change anything
What is wrong:
With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)
When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST stucks after 3 Debug Codes on Code C2...
