Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

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 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.

TV wont power on, clicking noise and flashing standby led


Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)
