Greetings!

This sounds like a degaussing (named after 19th century scientist Carl Friedrich Gauss) problem. This usually occurs one of several ways:

1. The TV fell down and went "boom".
2. Junior held a magnet up to the screen when you weren't looking.
3. There is a large, unshielded speaker near the set.
4. The TV was rotated in relation to the North/South magnetic poles of the Earth while it was running (yes, really).

All televisions have a degaussing coil built into them which is activated momentarily every time you turn on your TV. This typically will cure all minor anomolies over the course of a few days. However for a severe one like you have, it will probably require a trip to your friendly repair shop. I, personally, do not charge anyone to perform this service because it takes, literally, 5-10 seconds to degauss a TV. I simply ask them to remember me next time they go to buy a new TV or need service work. I can't say that your technician will do the same.

In the case of the first instance of the TV falling down and going "boom". If it fell with enough force to warp the shadow mask built into the picture tube, then all of the above information means nothing. The set will require a picture tube replacement to cure the problem.

Hope this helps,
Rob

Although tv is showing picture the colours only showing background etc are green and blue


Hello
Your TVs red colour output section has the trouble. There is no red output at the red cathode of the picture tube. The red, green, and blue output sections are on the picture tube base board. In some Philips model, these will be consists of transistors, and some has an IC or Tree ICs for three colour output used. You just open your TV, measure the voltages at these three cahodes. There will be markings on the printed circuit board for these cathodes marked as [Rk,Bk and Gk].
In your TVs case the voltage at the Rk marked pin will be higher that the other two cathodes. This can be caused by an open drive transistor or an Ic whichever may ysed there. If it is transistor, just replace it with a same type and number, as in the ace of ICs the related Ic, must be replaced. If only one Ic is uded for red, green and blue outputs, that Ic must be replaced.
If you need any more assistance, feel free to get me through Fixya. Ok.

Want to use the tv to play the Wii, but when I turn the tv on it only searches for channels, but can't find any. It then says to check cable connection and search for channels again. No channels found. It...


Ok, the Wii connect to the tv thru the Audio/Visual connections, generally at the back, or side of the unit, usually they are Yellow, Red, and White, or Blue, Green & Red. Please ensure you are connected Colour-to-colour, and then on the TV or remote, select one of the Auxillary, A/V inputs.Then you should see the Wii picture on ya TV. That is why you cannot "find" anything on scanning.

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.
