Re: LCD TV 26 Stay in Standby mode Red led
What do you say about univelsal PSU?

Just received it today from a friend.
Auto shutdown by the supervisor IC because of an under voltage condition with 12V output rail (dropped to 10.5V)
The same rail also does this when the PSU is in standby mode.

The leakage keeps climbing at a steady rate but slowing down when it reaches over 800mV or so. I didn't measure exactly at what value it stopped or if it's even stopped at all.
What could have caused that?
First time I have seen such behavior.
3.3V and 5V rails don't have the same... -
Hi,
I have this board, where I have exchanged the LGA1151 socket. During testing I discovered, that the large PCIEX16 slot won't by no force work in x16 mode, but keeps to work in x8 mode only.
I tested this with GPU-Z, also with Render Test (but tried also Furmark and Heaven Benchmark - no effect).
Tested on Core i5-9600K as well as on an Pentium G5420 and MSI NVIDIA GTX1070 and 2 other cards, including RTX3060Ti.
Board architecture definitely allows x16 mode, as all 16 PCIe lanes are present between CPU and main GPU slot (nearest to CPU).

Hi all,
My UN65MU6300FXZC is dead and the standby LED stays off. The power supply is good. The main board is BN94-12434A.
Disconnecting the main board from the power supply makes the backlight come ON.
I did disconnect the panel cables and the WIFI modules, the board is still dead.
I did read in many posts that IC1604 25Q40 becomes corrupted. It has proper 3.3 volt on VCC pin 8. I did read that if I post its dump here someone can fix it. Is that right?
Thanks. -
HP 850 G3 i get black screen and unable to wake the computer from sleep or standby mode. I have to hard restart the laptop. Any idea?07-03-2024, 06:25 AM -
Hi. I have the following problem with my TV. After connecting to mains, the standby led (red) turns on, but TV is not responding to remote control or buttons on TV. After some measurements, I found out that +5 V standby voltage is present, but I dont have ON/OFF signal coming in to turn PSU on. It stays at zero volts. After looking at the schematic of the mainboard, I should get ON/OFF signal coming in at the R1402 resistor, but it stays around +3,5 V. So I removed it and I was able to turn on TV with buttons on TV, but not with remote control.
What could be the problem ? Thanks...01-21-2024, 03:39 AM
