Picture is blurry with rainbow shadow


Hello,

This problem is very common with rear progection TV's.

It is related to one or more of the colour guns being out of alignment. The only way to correct this issue is to have a technician come in and fix it or bring it into a repair center. I personally would suggest purchasing a new TV. The cost of getting them aligned is usually more then a basic LCD.

Hope this helps

Has a double picture and looks rainbow


A double pcture with two different colours??? more seriousely the rainbow effect could be of an appature grill un hooked in one of the three tubes (THIS IS DANGEROUS IT COULD IMPLODE) you should have a proffessional looke at it and you should NOT USE OR MOVE the TV until then.

Good luck!

Coulour conversion Looks like three D how do I reset


if you go into your setup menu, you will find an autoconvergence option. just select this and it will autoalign. this tv is known for a loose solder connection causing a fuse to blow and you will lose all convergence (getting rainbow bowing at all sides of the picture) let me know if you can solder and want to tackle this repair. estimate = 100-200 $

Screen was pushed in, takin covering/surround off and fixed screen, replaced covering/surround but colour not right, can see rainbow effect on pitcure. is there a certain way screen must go to transform...


If this tv has a feature called magic focus or perfect focus which is a button inside door that flips down on the front, then it has sensors on the inside of the screen. When it was pushed in, these were probably messed up and will cause a poor picture. It may be difficult to get those realigned. Magic focus will not work right until they are realigned.

Rainbow colours on the screen


The projector is starting to go out in it. Depending on your financial situation, you can take it to a shop to have it looked at, or replace the TV. Depending on how long this has been happening, the Pioneer projectors usually last about 100 hours once this happens before they burn out completely.

Picture distortion


Sounds like convergence is off. Need new Convergence amps. Could cost a couple hundred. Check around. If it has an auto converge or manual converge try that first. Check menu

Start bt realigning the convergence by using the auto focus switch. If this doen;t work, you may have a bad convergence chip. Good Luck
