Question about JVC AV-32850 TV

TV will not turn on

JVC AV-A21M3 ON TIMER light is flashing constantly. I manually turn power off and then on, the light quits flashing until I try to turn on the TV with the remote. I get a quite click hum and then the ON TIMER light starts flashing.

What is the problem? I see it is posted on several blogs and on other model JVC TV but no fix is posted.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

TV turned off itself and timer light (red) keeps blinking


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

Jvc tv av-32d502 timer light is flashing will not turn on


Hello, I am a tv tech. I worked on a JVC AV-32D502 today. Problem: led flashes / no power or picture at all. Same as trobertson52's set. The microprocessor is bad in my machine. trobertson52, if your sets' relay does not click when the power button is depressed you most likely have the same problem or the standby power circuit is at fault. That circuit supplies +5 volts to the micro.

Edtal you have a different problem with your machine. Your machine is going into shutdown. A number of circuits could cause this and would need to be looked at by a technician to determine exactly which circuit is at fault. High voltage transformer (HOT) \ Vertical Circuit \ Power supply are the most likely causes.

The set is shutting down because a problem has been detected. Replacing the remote will not help. Count the flashes and call a JVC servicer to get an idea about what the specific problem may be.
