Top 20 Toshiba TP55H60 55" Rear Projection Television Questions & Answers

Sounds like a bad power supply.

The most common reason for this is one of the two convergence chips, most likely are STK-392-110 is shorted.What I do in this case is get at the chips and unsolder all pins (each has 18) on both chips and try to power set up.If set should come on it will look bad but you will KNOW one of the two chips is the problem (under 15 for a pair) and both should be replaced at same time.If you reach that point and need advice or help let me know--have repaired nearly 1,000 sets with this problem in my time.

The model indicated here should only have a red power button, Please confirm actual brand and MODEL number.

Hi,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Good luck.....

I had the same problem after replacing several things and still having same problem, it ended up being a capacitor.

hello if you take the back off look on the power supply board you should see a plastic whites clip with 2 pins coming off it or possible 3 just push it back in .
it will be at the top of the power supply board i hope it helps

regards

Ur tv needed a new lamp.Ur current tv lamp,in the tv now.U used the tv about 4 or 5 hours a day.Like the last 1 1/2 or 2 years the tv in used?The lamp life span is over.

A standard computer cord or monitor cord should work for your set.

Hi,
Please few things...
1- Make sure audio and video wires are hooked correctly in AV input of tv and you selected that AV input in tv with its remote.
2- Also check your dvd has not been set on progressive mode if you hook dvd player through yellow-red-white wires with tv.
3- if dvd player is set on progressive mode, then hook it with tv by component video input, red-green-blue for video and red-white for audio.
Hope this info will solve your problem.
Thanks.

There is no reset button unplug tv for 30 min, although toshiba says you can do it for 30 seconds. Email me back if you have more issues. I have dirt cheap parts. hill6399 at yahoo

Have you replaced or checked all the fuses? Do that first, then if you still are having problems, email me back. I will send you replacement parts, very cheap, and will tell you how to install. hill6399 at yahoo

OK these cables go color to color The Yellow is Video the other two, red & white are audio, you select the EXTERNAL input on the TV, not a channel as such. These leads as said go color to color at each end... then press play, and select, step through each external input until you see your signal...
