TX-42F430S Lock up on power up

My Westinghouse TV sometime freezes on power up, getting stuck on the W logo. The only way to get out of this is to unplug the TV for a while and then everything is fine. The rest of my equipement is a Scientific Atlanta Explorer 8300HD and a Sony upscaling DVD, all connected by HDMI.

I'm I the only one with this problem, and is there a workaround ?

Re: TX-42F430S Lock up on power up

Hi there,
After contacting Westinghouse directly they told me to plug the set directly into the wall socket and that should fix the problem. I tried and same thing happened on Powersaver mode but on normal mode same problem didn't occur. So I guess I won't be saving $20 to $30 dollars a year on Powersaver mode! Still love the set.

Re: 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.

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.

Won't nothing but the westinghouse logo come up when i cut it on

Chances are it is the main board that needs worked on. You should find one of these part numbers on the board, this set has different versions on the main board due to different panels that were put in during production.

The solution posted above by geomach7 worked perfectly. This tv is pretty much a huge monitor with a tiny computer in it. Usually when your computer messes up a restart will fix it, this tv is no different. 1. Unplug both the TV and HDMI media source (in my case, my PS3.) 2. Wait 30 seconds. 3. Plug in the TV and turn it on (via remote okay). 4. Wait for the Westinghouse logo to come on, then disappear. 5. Plug in the PS3. 6. Turn the PS3 on. This sequence fixed the problem for me. Hope it helps, thank you so much geomach7 you're awesome you saved me hours of worry!

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

TV requires main board replacement because problem seems in video processing section.

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!
