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.

You can contact me at if you would like.

Re: Power light comes on with no picture or sound

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!!!

TV picture wont come on, led light blinking, we have sound

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Picture gone

If you put the back of your hand to the front of the picture screen does it make the hair stand out like static? If not there is no high voltage..Does the audio come from the receiver to the tv or to a suround sound system? My first suggestion is to disconnect the tv from every thing. Plug in an exterior antenna/rabbit ears or just a paper clip into the cable connector and see if you get any local channels. If you have none available, connect to a known good dvd or vcr and see if it works correctly. If so then something has died in the receiver modulator. It might then be possible to use only the audio/video outputs on the receiver to get everything working, however the problem could be deaper in the receiver and not able to be bypassed.....Let me know what you have tried and if anything works. etc.....

Blinking light

the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.

TV starts but Does Not show picture or no sound

The Tic Tic sound is a result of the high voltage shutdown circuit. Thats what the circuit does if theres a short in the Highvoltage sweep. like maybe a shorted horizontal output transistor??. The only way to really tell is go in and measure the start up voltage and if the Hivoltage comes up and shuts down its a fault in the shutdown or Hhv regulation circuit . if it dosent come up at all then the faults in the Horizontal sweep circuit . Hope this explains a bit? good luck
