Another Westinghouse LD-4655 luck out
Thought I would take a chance for $50. Wouldn't power on. Owner was told it needed a new main board. Got home, checked the power supply, it was fine. When I was testing for an Eprom problem, (pulling the backlite cables one at a time) I found that pulling the left one caused the set to turn on and light up on one side. I then checked the cable and found a short to ground. After pulling the panel apart, I found the short,. I put tape over the area ( both top and bottom) and it fired right up!

Hello, guys!
I have this Westinghouse 32" LCD TV that turns on, standby led lights up (blue) but no image. If I knock on the screen there's no backlight present. I took the back cover off and injected voltage on the led connector using a Led TV Backlight Tester, and no light at all, so... it must be that there's some bad Leds, right? Or there is some another testing that should I have to do? Any guiding I'll appreciate it very much. Thanks in advance!

Ok, so I know I know, it's a Westinghouse....lol It's got the backlights but no video. Likely the panel, but I'd like to take some measurements on the buffer board with help from you experts to confirm. See the attached pictures. In pic #1, there's a nice pin reference to use to take some measurements. The large IC in pic #7 gets up to 60degC when the TV is on.
So, backlights, no video, go! 🙂...06-03-2024, 03:21 PM -
Westinghouse 32" Smart TV (Model: WD32HBR105) . Originally stuck on logo with no response from remote and no firmware file available to flash via USB. Westinghouse Support stated it would require service but that wasn't a cost effective option. I used dental floss to remove the motherboard processor heatsink to identify what make it was (Mstar). Unfortunately that knowledge didn't help with a solution. After the heatsink removal it only displayed a completely white screen. I then decided to replace the motherboard with a universal 3-in-1 board but the white screen problem continued. This...10-27-2022, 06:32 PM -
Hello all!
Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .
I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next.... -
Hi there,
I hope you can help me solve the problem with my Minisforum UM890 Pro. It's not booting. It pulls 0.5A at 20V with no RAM installed. That seems like a healthy current draw. The core gets the required voltage and heats up. However, when i install RAM (known good Samsung DDR5 4800 SODIMM) it pulls 0.1A at 20V and there is no voltage at the core. I tried both slots and different RAM, but the symptoms stay the same. I tried removing the BIOS-battery and pushing the reset button for > 10 seconds. I replaced a RT6228A synchronous step-down converter that was getting warm when...10-15-2025, 01:22 PM
