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!

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.... -
I've got a Dremel 8220 here that's had maybe an hour's use on it tops from brand new, so the brushes are definitely fine.
The fault is it just doesn't switch on sometimes. This can be after you've just used it or from cold. If you pull the battery and re-insert it will fire up straight away, every time, so it doesn't seem to be a physical issue with the power switch. Once on it works perfectly until you switch it off again, then it's pure luck whether it fires up again or not without pulling the battery.
I've not really worked on these kinds of tools before so would appreciate... -
