Question about Projection Televisions

1 Answer

I have a Mitsubishi 65" HD-1080 big screen tv. Today when I turned it on it had a red shadow all over it and the red tube was off by about an inch. The TV has an automatic convergence function that I did which fixed it but within about 5 minutes the red was back. I tried again and cannot get the red bulb to move back over to the white cross and line up. The TV is about 4-5yrs old. Has worked great up till now. Any ideas on how to fix?

How do I reset big screen tv to 1080 on remote


You don't.
It should automatically switch to 1080 when and only when there is a HD signal present. Otherwise it will be in 480 and you will need to use the format button on the remote to change the picture size. If it does not switch to 1080 and you know for sure you have a true HD signal present, there is a problem with the unit.
Hope this helps,

Blue and red overlap shadowing


convergence ic's are your culprit. they are responsible for aligning the 3 colors your tv projects onto your screen..

Big screen showing double and red ghost color


Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.

Problems with my Mitsubishi hd1080


If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad.
I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced.
I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's.
Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability.
Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat.
If you are a "do-it-yourselfer" here is a link with the directions and pics.
