SOURCE: JVC AV-32730 36" picture problem..

From what you describe, a solder joint has probably cracked loose in a power supply or deflection circuit, which is quite common. Since you do sometimes see a good picture, all of your major components are fine. Repairing cracked solder joints is a very easy procedure and definately worth fixing on a 32 inch TV. The first 2 digits of the model number indicate the size of the TV.

Sounds like U have an antenna or feeder problem. Get it checked out/ check it out. If in a strong signal area, try a simple indoor antenna for comparison. If in a marginal reception area, it could be your antenna is inadequate.

SOURCE: no power

Replaced the C226 capacitor. Using advice from this web site, found the capacitor, and yes it looked burnt, went to Radio shack and for $1.69 bought a new one, put it in, and we were all set. Does have to be soldered in, in all it took us about 1 1/2 hours. Thanks for the tip.

SOURCE: 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.

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.

Hi there TV is a JVC AV-36F713. Turned TV on a few days ago and nothing. Red flashing light on bottom of TV. Looked it up and manual said needs repair etc. Any ideas? Thanks Tim Also...


Hello Jim O'Connell,
Welcome and thank you for using FixYa!
To answer your question: I would suggest having a television repair professional pull out the power supply board.
They will need to remove the board and check it for bad (cold) soldier joints, bad capacitors, and lastly, to use an Osilliscope to test the +5v and -5V transistors on the board. If they can't diagnose the board, they can use the part number to order and install a replacement for you. That should fix your issue.
Have a great day!

JVC TV has flashing red light in front. TV won't turn on when red light starts flashing. After unplugging tv for a while, TV sometimes turns on but screen is shaking violently. Any flashing lights...


sometimes a leaky filter capacitor in the power supply primary section could caused this problem,or a loose solder connection in the power supply section

Tv just shut off and won't power up. No lights nothing. Tried unplugging and plugging back in. There is power to the outlet. I told my dad it was toast.


You are correct. If you get no image or text from the screen indicating it is trying to operate then it is time for replacement or service.

The digital clock on my 30"JVC is showing in the bottom of screen


The menu screen does not function the display. Without the original remote or a universal remote that does not have a display button, try unplugging the television for at least 2 minutes or more and plug the tv back in. This should reset the tv display. If the universal remote has a display button, depress the display button until you get the desired display results. Reference the user guide below for the display button.

JVC AV-36F802 Shuts off after turning on, then red timer on light flashes.


You are describing Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE cross reference at nteinc.com Get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!
