Question about Toshiba CN36G97 TV

2 Answers

Power light comes on with no picture or sound

I received a free TV yesterday. The only catch is that is doesn't work. I knew this when I got it. It is a Toshiba CN36G97. It was manufactured in April of 1998.

The previous owner owner tells me that they had NO problems with it until one day it just wouldn't come on any more. At that point they gave up on it and got a new TV. This one has been in there garage ever since.

The only things I know for sure is that the power light comes on at the same time a relay clicks over. There is a black box next to the relay that begins to get hot shortly after the relay clicks on. It is labeled as a resistor but looks like a relay. There are no obvious signs of overheating like smell or discoloration. The inside of the TV is VERY dusty so I think my first course of action will be to clean it out.

Any suggestions? I will be getting the service manual for this TV shortly as soon as I can find a reasonable place to get it from.

A little background on myself. I am a very experienced electronics tech I was in the Navy for 6 years troubleshooting and fixing aircraft electronics. The only thing stopping me here is that I don't have allot of TV experience. So most things I do will be guess work till I get a service manual. I am very aware of the voltages inside TV's and will take apropriate precautions.

I hope that is sufficient information for now. Basically I need to know what could be wrong and where to get a manual.

    After further cleaning and inspection I found heat discoloration under two large diodes. Could they be bad or just normally hot? I couldn't see this under the blanket of dust that used to be in there.

    I will definitely check the diodes... I need a new battery in my multimeter... I use it too much I guess. :)

I would think the diodes are bad. If there is definite discoloration somewhere the board as been hit?. What's funny is a lot of times dust can cause a lot of board failures from static electricty. But I assume when you receive the manual and have a meter you can test the loactions to see if the meter reads the proper volts?. Good luck!!!

Yamaha HTR-5063 is connected with new LG smart TV with HDMI. Today no picture or sound on TV. How to fix it ?


First, you need to identify which box the problem is in. Does the TV work with other inputs? If not, problem in TV. If it does, then the problem is in the Yamaha.
Once you know where the problem is, you can proceed to fixing what's broken.

As far as the TV is now at any service center, it will be wiser to make it repaired there. Otherwise, you might have to spend more; sometimes will get it back in irreparable condition. I assume that, you will understand my words. Gopakumar Gopalan Google

The picture will go black and the sound will go out. At the same time, the green power inicator will flash. Then the picture and sound will come back on for several seconds and then it will go out again....


My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions:
Please turn ON the TV. While holding down the RESET button on the Remote control, press the POWER button on the TV. The TV will turn itself OFF, then back ON again. Release the RESET button.The TV will go thru the initial setup, and should work normal.
