Why iq770 overheat and distort color

Your color wheel is going out and needs to be replaced. Toshiba does not list a part# for the color wheel. They expect you to have the whole light engine rebuilt. You should be able to find one on ebay. Or other sites like that. Good luck to you.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced.

Could be either one. Best bet is to find a friend to try out your monitor on his computer or try his monitor on your computer.

When did it start? Have you checked all connections?

if this is an older tv and your state might have changed to digital programming then i would suggest trying to look at the back of the set and see if you have anything to fix this problem or you might want to CHECK AND SEE IF YOU HAVE VIDEO ON or CABLE on or TV on. Sometimes if you have Antenna switch to cable then your channels would be red and picture distorted. change the antenna to air for tv. or from tv to cable.

for the noise distortion check out the antenna if it is still good or connected

If you`re talking about colored spots in the screen, then you may have a degauss problem. It was frequent for those sets to have bad solder joint on the degaussing coil connector or thermistor next to it.If you`re handy with a soldering iron these connections would be near the a.c line input. good luck and don`t forget to unplug

Try to check the monitor with a different PC. If it does the same its a monitor issue and needs to be replaced. If you dont have another PC, then try to go to BIOS of your PC and see if its the smae over there. If the display is still distorted in BIOS, then its a monitor Issue. Else you need to reinstall the graphics card driver from device manager or need to update the driver or reinstall the O/s.

pls. degauss your monitor. thats why so many colors appearing.
