Venturer tv plv16198 19"

If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

First thought would be to have a service call scheduled to check your signal at the TV. The cable co will meter it out. Some companies can do it via phone conversation. I would venture a solid guess that's your problem. Hope this helps. If you still have an issue, post a comment and I can help you troubleshoot further.

Replace power supply or fix bad caps

First a couple of questions:

1) What is the make and model please?

2) When the picture freezes, is it like a snapshot photo? or does the screen blank?

This sounds like an interruption in the digital data stream. If the picture remains on the screen, the "new" frame information is not being received nor processed. This can be as simple as a bad cable connection or noise on the digital information data lines.

Check to see if there is any pattern to when this occurs. For example, does it happen more frequently after the set has been on for a while? Try cooling down the set to see if temp effects the behavior.

Please update this and we'll work to resolve it.

Thanks,
Dan

Sounds like a probable main board issue

Source box problem......nothing wrong with TV............T.

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

From what source ? Does it happen when you play a DVD ?
Cable direct? Cable box? Satellite box?..........T.

Digital cable source box at fault.
