More likely it's because of power circuit of your TV set. If you are not trained enough in repairing TV sets, appeal to your local repair center

There is a defective electrolytic capacitor (470MF/16V) on the main board that went bad, it will causes intermittent, slow, or not power up, the location number of the cap is not marked on the board, please see the attached photo to locate it.

Westinghouse tv turns on power light blue works for 3 minutes then turns orange


This is going to be associated with your inverter or your display board. Some cases they are the same board. You will have to take this apart, find the board and then find a replacement.

Westinghouse model tx-42f430s won't power on


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...

MWe have one of these tvs and this morning it wont turn on although the light in front is red and it still wont turn on


I had the exact problem and couldn't do the factory reset or another reset that a Westinghouse tech told me to do over the phone - BUT I FIXED IT! This is what I did. With the TV facing me and power on and connected to my cable antenna (like normal - ready to watch TV) I took my right hand and started pressing all different buttons on the side of the TV in different order at random. All of a sudden the big W came on the screen so I called back Westinghouse technical assistance and she told me go to menu - then TV - then scroll down to channel search. Since all my cable channels are on channel 3 on the TV - the search found that channel and the picture and sound came on and works fine!

Unable to get signal input when i connect my pc


There are several fixes for this problem.

1) You can unplug the TV for a few minutes and try again.

2) You can turn off the TV then hold the Power button down for at least 10 seconds (resets the processor)

3) Go to the settings menu, select factory reset.


Good luck

Won't power up past the W logo.


Try hitting the input button and selecting the correct source. Mine is YBPBR1. That should get you a picture!

TX-42F430S Lock up on power up


I have a similar problem with my TX-42F430S; Mine freezes when changing from Comp 1 to Comp 2. unpluging and waiting was the only fix. Just recently my TV just started turning off(after about 30min of watching) and the led will flash blue. I need to unplug for about 10min before it works again. Getting frustrated and I have contacted Westinghouse to send for repair. only had the TV for 3 months; connect to Roger Explorer HD box.
