no i have no tv experience.I can get a meter.I have worked on electronics before.
TV Technician: Rick williams, Technician replied 8 years ago

Your problem, digital meter in electronics almost impossible to verify anything shorted or opened with out it. This is a test procedure I would have a friend that knows something about TV, Almost impossible for a novice with no experience with projection repair.

A projection can have a few things wrong with it that can cause this

 

1. Power supply failure. Measure at the collector of the horizontal out put while set is off, or remove this transistor then measure the power supply voltage. B+

2. Horizontal out put failure or horizontal circuit. Check to see if the collector leg is shorted to ground.

3. Vertical IC failure or vertical circuit. With out Oscilloscope all you can do is change out to test.

4. Convergence Amplifier, convergence circuit. By removing the STK chips the unit will start if this circuit is bad

 

Either case if you are able to troubleshoot this unit, you should Down Load the schematic, Because it will not be a simple repair for a Novice, I do suggest calling a in home service provider, Would not want you to cause any harm to you or your set further, Normally repairs for these units are around 280.00.

 

Below are basic pictures of the parts mentioned above.

 

 

Horizontal output . Horizontal out put bad vertical IC watch someone do the repair To the convergence circuit.

 

I hope I helped answer your question.

Well Good luck friend, and if my efforts on trying to help you save on those large labor charges are appreciated, feedback and a bonus will be appreciated

 

Thanks.

When you turn the power on the timer light blinks 8 times but the tv doesnt come.I was hoping the 8 blinks was some sort of code to tell me what was wrong with the tv.
