by high-techHello everybody, I could use some help on this one... It's got me guessing...
I took pictures of all the boards and the pin out of the connector on the power supply that goes to the main board... I measured all the pins in relation to chassis ground, here are the result.
(B13v)1. 12.7 volts cycling (Vamp) 2. 12.7 volts cycling
(B13v)3. 12.7 volts cycling (PWM5) 4. 1.0 volts cycling
(OD_LE)5. 2.8 volts cycling (PWM4) 6. 0.9 volts cycling
(OD_ON)7. 2.8 volts cycling (PWM3) 8. 0.9 volts cycling
9. ground (PWM2) 10. 0.9 volts cycling... -
by DynaxSCHi,
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... -

by momakaMore eBay specials: this time a Gigabyte GP-P450b 450W ATX PSU for $8 with free S&H. Listed “For part/not working”, as usual. Showed up in a beat up EVGA box without any padding… but that's understandable given the total price. PSU made it out fine without damage. It's a non-modular (yay!), pretty modern-day looking PSU with a black paint and all black cables (meh, not my favorite, but figure it's good to keep a few of these in case I do need one for a more modern PC build, just so my old gray boxes don't look too odd in there.)
And a shot of the label:... -
by usbdeviceHi all
There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.
It's my dad's old monitor. He...-
