Re: Westinghouse EW46T4LZ
Not wishing to cause a storm but I have in my limited experience never had a problem with using a 1K resistor from P_ON to supply or ground.
Many power supplies for which there are no diagrams available will power up the secondary voltages taking P_On to 5V but with some boards its the reverse and P_On has to be taken low. Using a 1K resistor I can honestly say has never caused problems.

Hello,
The idea is to use a transistor to activate a latching relay once a voltage is applied but to prevent a constant voltage from being applied to the relay coil, I thought it might be a good idea if it were possible to make sure that the voltage applied to the coil is temporary even though the source voltage could be "ON" for long periods of time.
This is the circuit that I came up with. I have not tested it yet because I don't have the relay yet, though I am looking for anyone who might have experience with this kind of a setup to hopefully offer some advice,... -
Disclaimer Firstly I am by no means expert and this is still a learning experience , I buy broken stuff , with the intention to fix or learn something by failing.. I wanna break this into a few sections, please feel free to mention the section if replying , to assist me on getting a better understanding
Part 1 , identifying Rails .. So for the record , I understand on NVIDIA cards there are several Rails. Along with their Supposed Voltages ( Voltage depends on age/ generation )
Part 2. Blown / Missing component check .. I purchased this from the original... -
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....
