is the TV a CRT, plasma,LED or LCDCRT is a very old type which consists of a vacuum tube that has an electron gun that shoots energy at the front of the screen where pixels divide the light into 3 colours RED BLUE GREENLCD, LED and plasma are the most modern of which run in high definition. CRTs are very bulky, while the other 3 types are slim and light, if it is a CRT, drop the colours to a lower setting and it should silence it, I had to do this countless times with my computer's monitor as it is a CRT.
No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.
I don't know your model, therefore I will tell you genericaly what the problem may be.
There are many things that can cause this type of fault. The response of the video amplifier stages would have to be checked right up through to the output that drives the projection. it is also possible that there is a fault with the colour demodulator. If the set uses projection tubes it is possible that the tubes are weak, or there is dirt in the optics. Colour demodulation problems can also cause the colours to not be correct. Many models using tubes have an optical transparent cooling fluid in front of the tubes. This fluid may have to be changed.
is this a rear projection tv? a table top one? how old is it because if it's over a few years old, then it sounds as if the bulb may be going out but without having more info, it's hard to give an accurate advice.. please let me know if this helps..
If the repairman you had look at the set is used to working on projection sets, have him come back and Re-Solder Connector Px801 (Edge Connector) On The G-Hyper Module. (Pins 1 And 2 Of Px801 probably needs to be Re-Soldered) Otherwise, find a different repair person.
