Question about Toshiba TLP 261 Multimedia Projector
Please help, I have a discoloration pattern on my projected picture (red on black, 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 shoul fix the problem, it was said. I disassembleg my projector up to the point I have been wondering where the filter is, actually. I attached a picture. Are those indicated by the red arrows, or the panels indicated by the green arrows, or which?
This is what Tishiba indicates in the manual for your problem:
Lamp went out during use, or won’t come on
→ Returns to standby after about 2 minutes. If the projector fails to
operate normally after turning the power back on, either the lamp
needs replacing, or there is a problem with the projector.
• If a lamp burns out, replace it with a new one.
• Unplug the power cord, and contact your dealer.
Obviously you are at the contact your dealer part which isn't really a good situation since you are in Brazil. Researching parts will get back to you when I find something.

reset the settings to factory default. then make sure that the input matches the signal and that the cables are working. if you still have a problem, and the entire screen (including the initial toshiba screen) is entirely green tinted, you may have a main board issue.

you have a few issues. first is the yellow in white. the light filter on the blue lcd panel is fried due to excessive dust and heat. unfortunately, you may have to replace the whole optical engine. as for the flashing horizontal lines, the power supply isn't cooling down and the caps are drying out, causing fluctuations in voltage. so, replace the power supply.

If all the fans are running and you are sure, than it sounds like you have a bad main control board. Double check that all the fans are running. If so you will need to replace the main controller, this is the board that the fans are plugged into.
Thanks the Projector Guy
