Re: technika 42 lcd 910 power probs
these mosfets are probably my fault they have gone faulty , i accidently shorted one of the big caps when taking 24v reading on the invertor board , so i suppose the rapid discharge from the cap damaged them , hence me fault on the T.v changing ..oops

I have a samsung QN82Q70RA powers on then powers off. Using some info on the interwebs. I disconnected main board from power supply and backlight shows blue and stays on indicating power supply is good. So next I unplugged one on the lvds cables that connects to screen( I think other side goes to tcon board?) i can get a blue screen and if I press the picture button on the remote i get rain sounds and birds chirping. A lot of videos suggest using kaptan tape to cover the clock signals, but I've been unsucessful there.
So I thought I'd just quit messing around and come to the best site... -
Hello all,
I'm stumped on this guy, so wanted to see if anyone has any further ideas:
Intro:
This is an Acer Nitro 5 AN515-55-55M1 with unknown prior history (bought "as-is" on eBay). It charges the battery and powers on from both AC adapter and battery, so I think this rules out main power issues.
Upon attempt to boot, it will "reboot" (meaning powers down and then powers on again) only once, and then stays stuck in a status of lights on / no post / no monitor. Powering on with fn+esc maxes out the fans on first boot attempt,... -

No blown caps
I searched for this model but nothing comes up...11-29-2024, 11:21 PM -
Hi all — I’m trying to diagnose the plate amplifier from a Definitive Technology BP7006 tower.
Symptoms:
- The amp powers on (red light illuminated)
- No subwoofer output
- Main towers still play normally through my receiver
- No audible hum or noise from the sub section
What I’ve done so far:
- Verified fuse continuity
- Visual inspection: no burned parts
- Confirmed speaker driver reads ~5Ω DCR
- Board ID: LT-C126 (stamped on the PCB)
- Cap glue confirmed factory adhesive, not leakage
- Using a UNI-T...11-05-2025, 09:06 AM -
Hi everyone,
I’m working on an ASUS B5402CEA notebook.
B5402CEA_MB_R2.2
HA4YT LA-L861P
REV:1B
The board powers on, fan spins for a few seconds, then it shuts down by itself.
I suspect the BIOS might be corrupted.
Could someone please check and clean (repair) the attached BIOS dump?
I’ve also attached a few photos of the motherboard for reference.
Thanks in advance for your help!
