Question about Toshiba TLP450, TLP451, TLP650, TLP651, TLP670U, TLP671U Projector Lamp - TLP-L6 Projector Lamp
Please help, I have a miscoloring fixed pattern on my projected picture (red on black, black replacing red in the area, etc). It's not only in corners, it's a semi-circular pattern almost all-over, very disturbing. I saw another piece of advice talking about the polarising filter possibly being tarnished because of over-heating. Replacing this one should fix the problem, it was said. I've disassembled my projector up to the point I have been wondering where the filter is, actually. I've attached for you a picture with the insides of my projector. Are those indicated by the red arrows, or the panels indicated by the green arrows, or which?
P.S. I have replaced the lamp, nothing changed.

If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.

Some newer sets appear that way when there is NO signal to the set. That and my Sony looks like that when the bulb is burned out.

ok i found a couple more things...apparently you dont have to remove the battery.. I found this site that tells you two "jumpers" (solder squares) C88 i believe under the network card. But if you follow this link and follow the directions it will get you going again.
I don't know exactly at what stage you are at and i hope i didn't cause any trouble but this normally is how we take care of this problem. Unless once in a blue moon we come across one like this.

SOURCE: Bulb Replacement
the bulb hot indication has nothing to do with the lamp counter.u would have reset the counter as suggetsed by the manufacturer,
this problem is because of the following:
1) wrong bulb
2) cooling fans not working adequately
3) defective ballast
check the above for a solution

The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.
