Toshiba tp48d51 projection tv is making a clicking sound. how do I fix it. It begins clicking as soon as it's turned on. The red needs adjusting and I can't seem to get it right. How do I adjust...


Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps in solving the problem, also take caution, because it contains high voltage

I have a Toshiba 51h83. Everything works fine except there is an issue where the colors are slightly lighter on both the left and right sides of the screen.


this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)

let me know if that helps!

The picture on my Toshiba 55H70 is distorted. Most of the screen is fine, but the bottom left looks bent with all three colors misaligned. I tried adjusting the convergence some but it did nothing for that...

I have a Toshiba 55H70 TV. Lately it has been having issues with the screen. The picture will go out and theres different color lines, if we turn it off or unplug it and plug it back in it comes back. we...


Sounds like possibly cold solder connections on the convergence IC's I believe there are 3 in your tv. They are easy to spot big black IC's that have STK392-xxx stamped on them.. If your lucky you can solder the connections and be back in business. Sometimes because of the bad connections left unrepaired it will cause the ic's to fail then they would need replacing. If you have soldering skills you might try yourself. Be careful and make sure its unplugged. If you arent skilled at soldering I wouldnt recommend even trying it.

Toshiba 65hx81 65" Rear Projection tv. black & white color/green


Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck
