On plug in the red led blinks one long three short one long two short repeating, the power supply smells burnt, A13v on CNM801 pins 3,5,7,9 is 12.8 volts, it drops to 10.8 volts when the led is on long blink, pson pin 8 is at 3.2 volts dropping to 0.11 volts on long blink, the test point jumper marked STB:7.5 ON:11.8 measures 12.8 volts dropping to 10.8 volts on long blink. The set is powered down on the long blink and reboots while short blinking? Can someone help me find a test point for the run supplies?

Hello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.
> I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
> There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...01-24-2025, 11:51 PM -
Hi,
I have HP Omen 15-dc0001nh (DA0G3DMBCE0 rev: E) with blinking capslock 5 long and 3 short. Fans spin constans speed.
HP worked for 2 months after i repaired (before damaged by thunder via rj45 port) I removed LAN ic and powered on
Now with blinking capslock:
All voltage present on big coils, except +VCCGT (i don't know this need for booting)
I tried re-flash bios with known firmware- same result (now i don't have spare bios chip to test spi flash failure)
DDR4 ram is ok, tested on other laptop
WLAN and SSD removed,... -
I write this to maybe help another with this TV.
So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.
The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

Hi all,
this unit comes from a samsumg LCD TV LE32C530F1W which stopped working after making a strong noise like something was exploded inside of it.
I opened it and found that fuse FP801S was blown, capacitor CP814 was completely disintegrated and MOSFET QP801S was shorted.
I replaced all of them and instead of the fuse I connected a 100 Watt bulb. Then, without connecting it to other TV boards, I switched it on, but the bulb begun to blink.
I thought that maybe the bulb was somehow interfering with the normal operation of the power supply, so I replaced it with a fuse,... -
