SOURCE: tv trouble shooting

1)Check secondary fuse devices. 2)Check horiz output xistor=shorted? 3)replace w/equiv.or better part. 4)Check solder connects in horiz drive circuit. Replace small electrolytic filter cap in base circuit of horiz o/p==horiz drive xformer and xistor area,typically 1mf/160v,C531? 2b)not shorted==do step 4 anyway 5)still blinking?==check vert o/p,audio o/p and regulated o/p's

I changed capacitor C926 (1000Uf 16V) on main board. It solved the problem. I went with 1000uF 63V as it was readily available...it's okay to go with higher voltage. It was hard to fit it on because of the larger size but it worked.

SOURCE: fuckin jvc tv will not turn on and its really

Try to unplugged to the power outlet for 2 minutes, and then power on. Or for the meantime if it have protection circuit like surge protector disconnect that for the meantime. And then power it on.

If not there's maybe a high voltage circuitry problem if this is a crt type tv.

SOURCE: 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

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

SOURCE: When I turn the TV power on, the TV picture won't display, but the timer display (red blinking light) blinks momentarily and then clicks off. What is the problem and how much would it cost to have rep

check the horinzontal out transistors. call qualified personnel to fix.

I was playing a game and it made a sound then shut off now my on timer light is blinking. when i unplug and plug back in the timer light stops blinking for a second then starts again.


Something shorted in the set, possibly the horizontal output transistor or a power supply diode. The reason it starts blinking again after plug in is because JVC try to come back on if they were on when the problem started. In other words, if it quit while it was playing it will always be in the on position until the problem is repaired and it can be turned off normally. Have a shop check it out for you. There are a lot of things that can cause one to go out. Thanks

Blinking Timer Button


The tv must of turned on the timer by itself. They do do that sometimes. I suggest leaving it unplugged for 24 hours to reset itself.
If problem persists, you may be able to go to your menu and access the sleep mode timer and set it to 0:00 or OFF

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.

Digital Tuner or Analog


I have the JVC AV-27020 and had to download the manual just today. I checked where I got my manual and they did not have anything for an ACV-27020. The link for the TV manual I downloaded is below. Maybe it will help.

JVC AV-27020 TV Blinking LED, Static Electricity on tube but no sound and image


Sounds like a bad main regulator IC.. Try putting a 100 watt light bulb across the main AC fuse, turn on the set and see if it will stay on longer. If it does, replace the main regulator iC. If it does not, then it could be almost anything in the sweep section of the set, and or in the regulation circuit of the power supply. Look for slightly swollen capacitors in the set. good Luck please do not forget to rate this thread.
