I picked this one up today.
Previous owner says no signs of life.
TV looks immaculate and its a 2022 model year so I thought maybe the one connect cable was damaged.
Got it home and put it on the Kill-A-Watt power meter and it was completely dead.
The TV model is QN65LS03BAFXZA - version: CB06
The One Connect Box BN44-01066D / BN96-54788Q / BN39-02470A.
I immediately remembered EazyBone's Samsung The Frame TV no power....One Connect thread and am preparing myself to tear the One Connect open and hunt for dead parts.

Hi.
I have a laptop Dell Vostro 3501 which did not POST. When connected to power supply and turn it on, the keyboard backlight would turn on but nothing else. Sometimes there was 1 BEEP code indicating problems with BIOS.
Then I disassembled it to read the BIOS chips. It had 2 - 64mbit and 128mbit. I connected CH341A (with 3.3v mod) to both of the chips (still soldered on main board) and read them.
After I reassembled laptop back and tried to turn it on. Now there is no sign of life. Not even keyboard backlight.
Then I took the motherboard out... -

Picked this one up today.
No signs of life whatsoever. No red led light from the IR module.
Disconnected the mainboard to see if PSU was working and it was (LED backlights lit up).
Checked the power button for continuity when buttons were pressed and I got readings.
Disconnected various components (speaker, wifi module) with no difference.
Checked mainboard's fuses (found 3) and they were all good.
I looked on shopjimmy to see what components I may have been missing and I saw that they were selling EEPROMs.
Then it dawned... -
Hi Guys,
I'm trying to repair this Asus ROG Strix notebook for a longer while now.
Mainboard is G531GW rev. r1.6
When attaching power notebook straight up turns on but no picture or similar signs of life. Voltages are all there (VCCCORE, VCCSA, NVVDD, 1.05V, 1.2V, 5V, 3V, 12V β¦. Only VCCGT is missing, but that is ok as far as I read), no obvious shorts on any rails. CPU gets hot quickly without heatsink, GPU gets moderately warm and PCH gets warm as well. EC should be good: power button responds to a long press and after a while the CPU fan kicks in.
What I have found out...
Working...
