TV WAS WORKING FINE, TURNED IT OFF, THEN TURNED IT ONTHE NEXT DAY


Your tv might have a defective power supply, and/or convergence circuit. The initial cause of the problem, if it is the convergence circuit, is usualy a loose conection on one or two jumpers close to the convergence output circuits (STK392-1110), in with case this chips might need to be replaced and a pico fuse of 5A on the power supply too. I hope this help you.

Red lite comes on but tv will not power up.


Follow the solution for service port 'jump start' with a usb plug. Plug your cell phone charger in next to the TV. Touch the metal prongs of the service port with the metal part of the usb until you get a brief 'flash' on the TV. Then turn on the tv set. It takes patience and a flash light to do this, so you can see what your touching, as my husband couldn't get it to work, but I could.

Toshiba TDP SC25 projector


The manual says it might be because the power went out when it was on. Just a note here, as projectors age they become more sensitive to power outages. When not in use turn off completely if you can. They have an on/off button.

Otherwise not sure but think you may need to replace the fan. Try cleaning it first but gently.

I have a 56" rear projection panasonic tv when i turn it on green lite come on then a lamp lite comes on red no picture or sound lamp lite flashing


Doulbe check in the owner's manual, but this is usually an indication of a bad lamp or fan error. There will be a table in the owner's manual listing the error codes as shown by these lights. I can't give you more details without the exact model number.

hope this helps,
Dan
