Dried out capacitors that conduct electricity very poorly when cool will begin to work normally for a time when over heated, lenses and display components that are warped may also regain a workable shape when hot. It's very common for integrated circuits, etc. damaged by heat or electrical surge to show symptoms cool that don't manifest when the device gets hot. But they are indicators of an imminent failure.

Most likely the 3LCD component that generates the picture or the integrated electronics themselves have been damaged. This can happen over time from heat for example if the air filter doesn't get changed or from a power surge.

Hi Mandy

Think you have a problem with the cabel or if you could adjust the channel for the correct signal. Maybe the tv-chip on the consol are broken, and you live to far from me for me to help :)

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

My nec 42" px-42vr5w plasma

Despite the fact that you have posted this as a question about a kitchen range, I can tell you waht the problem is anyway!

The plasma screen is controlled by hundreds of seperate connections at the top, bottom and sides of the screen which use electrical pulses to signal the pixels on the screen what colour they should be. If the connection to a bank of these connectors fails (in this case either at the top or the bottom of the screen) then they will usually die and that portion of the screen most commonly goes black. Next most common is that they go white as yours has.

This is absolutely NOT a DIY fix. You will need to get it to your local TV shop. If you're lucky, they will find and fix the poor connections. If you're unlucky, the plasma panel has had it and they won't be able to repair it. A replacement panel supplied and fitted is probably about the same price as a nice new, updated plasma TV, so if the issue goes that way, consider scrapping and buying a new one
