Hello
If there is sound output from its speakers, when turn ON, and catches a transmission, the fault must be to its Timing Contrrol board. This board also known as T'Con board. This is a common fault to all LCD tvs, irrespective of their brand.
If sound output also absent, the motherbaord [Main board] has the fault. Whicheaver it may, this is a skilled work, and can only be done by an experienced service techinician. If you know anyone such, just contact him/her.
Otherwise contact the nearest Authorised Service Center for Toshiba at your town. OK.

56 in toshiba rear projection tv. When u turn it on the green light comes on and a yellow light flashes 15times followed by a click sound. No picture. What does this mean?


Try going to www.toshiba.com to research your problem and what the 15 flashes of the yellow light means. Try unplugging your TV from the wall for about 30 seconds and then plug it back in. This will re-boot your TV (like re-booting your computer). If still no picture, if could be your bulb, motherboard or color wheel.

My Toshiba 55SL417U will not come on. The led light blinks, but screen remains black. It is no longer under warranty. Is there something I could do to fix it?

The main board of your TV should be troubleshooted. It is a very skilled work, and you must have sufficiant knoledge in electronics and expereince to work with digital printed circuit boards. In most cases, the repair to this board will be immpossible, and may replace it as card basis.
This is the picture of the main board to your tV.2_4_2012_6_28_32_am.jpg

I have a 72 inch toshiba flat screen tv when turning it on the green light flashes it comes on then go right back off


I have researched the owners manual and it states to recheck the lamp door and make sure the lamp is seated properly and that the door is closed tight. I can email you the manual if you do not have one.

If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1-9 to ensure that the lamp unit and lamp unit door are installed correctly:
• No picture • Dark picture • TV will not turn on
If, after repeating steps 1-9, the problem still exists:
• In the U.S., call TACP consumer solutions at 1-800-631-3811.
• In Canada, locate the nearest Toshiba authorized service depot by directing your web browser to www.toshiba.ca; click "Home Entertainment," and then click "Support."

My toshiba TP50H15 color tv comes on then off and the light blink


The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

Tv clicks on red light comes on then begins to blink no picture


Well it seems more to be an issue with the ballast, that doesn't have enough voltage to keep on with the lamp. And the ballast is trying to ignite, that's why you hear that clicking sound. Ballast are not that expensive, they're running around 60-70 dlls, It's worth to try.
