At first it shows a pretty picture then after about 30 minutes or so the picture starts flickering and jumping and stuff.What should I do to fix that?
The problem in your tv is not external.
The problem is in the power supplies internal filtering.
On the primary side of the power supply main board you will find
a large electrolytic capacitor very near the fuse and the primary transformer( the small one). Next to this capacitor you will find a
large 5 watt diode.( black with a silver band at one end). Next to this you will find one lone 1/4 watt resistor. This resistor in conjuction with large electrolytic capacitor is responcible for the internal filtering of the high voltage side of the board. As your unit heats up( anywhere fron 5 to 30 mins) you will notice horizontal
flickering and prior to that red or green or even purple pixelation.
Check this 1/4 watt resistor for dark discoloration and or a bad solder joint on the solder side of the board. This resistor
is directly responcible for controlling the bias current to the high voltage regulators for the 160 volts DC. At no time should you handle or troubleshoot this board with the line plug in.
Even when this board is powered down that capacitor still holds a charge for up to an hour and can knock your you know what
in your sock. If you do not feel comfortable please take the board to someone else. Hope this helps.

I had the same problem. They told me it was a noisy signal or power. I cleaned the power with a line filter and unplugged the cable. None of this worked. I sent the TV back and am still waiting after 3 months for a new one. good luck......

Thanks!!!!!!!!!!!! That really worked!!!! AWESOME!!!!!!!!!
My picture jumps to the point where it is not watchable. Sometimes it stops jumping in a few minutes other times it will jump for an hour. Unplugging and reseting the tv does not help.
Same problem, any solutions???
The TV works great for about 30 minutes, then the picture starts jumping and rolling. Someitmes it stops after about 10 minutes - but then starts up again.
Other sets in the house of on the same cable system and we do not have any problem with them.
What can we do?
I bought a LTV-32w3 in Sept 06 and I have the same problem, but it didn't start until Jul 07 or so. I tried everything Westinghouse recommended and wound up sending the set back to them in Sept. About a month later, I received a new set and it has the same problem. It seems to me that Westinghouse either (1) has no idea what is causing the problem and/or (2) don't know how to fix it.
bad jumping flickering picture.
Same issue and I am pissed....any solutions?
what worked awesome???????
I have a Westinghouse LTV-27in HDTV after being on for 15-20mins the picture rolls everytime and them to make it worse the screen goes black after the rolling starts. Sometimes the rolling and jumping picture is at the top 2-3inches of the screen and the rest of it is black and rolling. This tv was not damaged by us and connected to the cable by the cable company and then rechecked the connection to make sure it is a clean connection by the cable people. We have two of the same tv's. The other tv did the same thing after a year for a month, now it's o.k on it's own. How and where do I get this tv repaired so we can use our tv? We do not have a warrentee on the tv. I would not recomed this tv to anyone.
I have the same problem, no warranty and I have torn apart the TV and checked that resistor and it looks fine. The boards are available to purchase on ebay, but I wondering which board is the problem. Have any of you fixed this issue? Thanks,
it used to clear up after 10 to15 minutes but it continues to flutter and jump all the time
