SOURCE: The TV will not turn on. The only thing that it

Look for cold solder joints in the power supply module and check the caps for leaking/bulging tops.

Its either the main or power board, check and see if you have a voltage change on the PSON pin when you turn the set on, if you don't then chances are its the main if there isn't a change I'd try the PS...good luck!!

Hi, I have a Westinghouse 42"


The only other thing that I would think to replace on this is the power board. You may have bad power going to the main board. Other than that you may be at the point of no return on that TV.

I am having trouble installing the wiring with my westinghouse. I don't know how to match up the wires. The Westinghouse has black, white, blue, and green wires, and my house wiring is purple, yellow and...


At the fan green is ground, blue is to turn on the fan, black turns on the light. I believe at your house wiring white is neutral and goes to the white in the fan. The purple and yellow are to switch on the fixtures, you can connect the purple to the blue, and the yellow to the black.

Changing the 3 speed switch on my westinghouse ceiling fan


If you are careful and take the hot coming into the fan from the power source and connect it to the colored wires one at a time, you will be able to find which one is high, med. and low. Then connect them. Hot in is L, 1 is low, 2 is med, 3 is high

My Westy 47 TV has a very strange power-up problem! First, I found that the power supply was bad, I couldn't repair it, so I bought a replacement from ShopJimmy. The replacement seems to be working fine, and sometimes the TV works fine. The little green LED near the bottom edge of the controller board lights up when you connect the AC power, as it should. There is also a small green LED near the upper edge of the controller board that apparently lights only up when the controller is working properly. I've replaced the 470 mFd, 16 V. 'Lytic on the controller board, as everyone says to do. I still observed about 0.8 Vp-p of digital signals on the 5 Volt buss with the replacement capacitor these signals looked kind of like a 300 kHz clock and some other misc. digital stuff, so I added a couple of 0.1 mFd disc ceramics directly across it on the bottom side of the board. That reduced these signals to about 0.4 Vp-p, but the TV still won't turn on. The orange pilot light on the front is lit, but neither the buttons nor the remote will turn it on. The only way I can get the TV to turn on is to do the following: 1. disconnect the two power cables going to the two lamp inverter boards; 2. plug the AC power cable in. The 2nd green LED on the upper portion of the controller board now lights up when AC power is applied. 3. plug in both power cables to the two inverter boards while the power is on. The TV now works fine - all of the lamps light up, good picture, blue LED on the front panel, the remote works, etc. However, if I turn the TV off, and try to turn it back on, the small green LED on the upper controller board goes off, and the set won't come on! I've tried holding the on/off button down for over 10 seconds I read that this might re-boot the controller to no avail. The only way to get it back on is to go thru the 3 above steps again. I've read that there appear to be several versions of the firmware, and I wonder if this might be a firmware problem. If so, how/where can I get the proper firmware to install? Any suggestions? HELP! Please If someone would like to call me, please do at ************. Thanks, Gary W3DTN
