I have a p52830bl. Once I turn the tv on it works fine then after about 5 min the picture turns to snow with some of the programing still viewable. I have "wiggleled" the coax cable and the screen will clear up then go back to snow 15 min later. (pain when trying to watch a 2 hr movie) I have tighted all the connections in the back and it still doesnt help. I just have to keep movinng the cable in the rear of the tv to get the picture to clear. I also hooked the coax to a diffrent tv, thinking it was a bad cable however the cable works fine. Can I replace the board and where do I buy one? Also where can I buy a reasonably priced screen?
lost in winter wonderland.
SOUNDS LIKE BAD SOLDER CONNECTIONS IN SIDE THE TUNER.
TAKE THE BACK OFF AND TRY TAPPING AROUND WITH YOUR DRIVER HANDLE THIS WILL LEAD YOU TO WERE THE PROBLEM IS.
THEN WE TAKE THE TUNERS APART AND RE SOLDER THE CONNECTIONS,BUT YOU HAVE TO BE VERY GOOD OR YOU WILL
MAKE MATTERS WORSE.

I had the same problem. It appears to be due to a bad tv tuner. Turn on your computer and leave the coax unplugged. Leave it for a while (15-30 min). When you see "snow" on your screen, you will be able to use the source button to change to another input and see if you can get a signal. I am running my cable through a dvd recorder and using the AV input to watch tv. Also, my HDMI, component and RGB work fine. After thank don't try to access the TV source until you have had your tuner replaced.
The failure with this TV is due to faulty ground in the tuner that is why when you wiggle the cable connected to the tuner the picture clears up. If this failure is not repair, it will corrupt the data on the eprom until the TV will not power ON anymore.
Check the info from this link to find more info on the failure of your TV.
Let me know if you require further assistance.
First, how is the receiver connected to your TV? If it's via coax, the most likely culprit is the coax from the TV to the rcvr. If you wiggle the coax and the snow goes away, you've found the answer. If it goes away, either get a new piece of coax or tighten the connection at both ends.
Offhand, if the previous system/connection works then we should leave that as it is. Coax-Sat Receiver-Coax-DVD Recorder-TV and TV should be Channel 3 (or 4).
On the new Sat Receiver, coax from LNB/Dish to Sat Receiver, yellow, red & white to TV. TV should be set to Video 1 or A/V or Video. There should be no snow, rather if no reception, it should be blue indicating video has muted in the absence of a good signal.
Did the cable person take a reading on the signal level at the cable outlet on the wall and did the cable person check the TV setting to make sure they are correct. TV could be set on the wrong channel also.
There is a convergence printed circuit board that likely has a few bad components. If you decide to get it repaired, the technican will probably check for fluid leaks from the picture tubes coolant area which has given problems on this model also. If the picture quality leaves a bit to be desired, it may be a wise move to upgrade to HDTV. A Sony KDS-55A20 model has a great picture and should be less than $2300. I just saw one at a local Sams Club store.
