If you plan on buying HDTV then it isn't worth
fixing,but if you areen't you could get an estimate
You might be able to get a good working box worthy
set from someone who just acquired HDTV You have
several options Prices are dropping and there are a lot
of sales going on now too.

    No one can tell you that without
    taking it apart & chiecking it
    it could be lots of things pwr
    supply,HV you cant tell what
    in a box without opening it
    thats why they tell you to
    take it to a service center

Tv shutting off timer light blinking

The problem you describe is not really related to a timer function being set. The unit is in shutdown and the light is blinkng to let you know there is a problem.
There are several possible causes. the most common is a failure in the vertical deflection circuit due to a bad vertical IC and possibly a capacitor, zener diode and resistor.

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.

JVC TV crisis.....HELP

yes... i actually work at verizon the tv is to old for fios because fios is so advanced we run off ot 720 to 1080 depending on areas. what kind of box is it? is it the hd box or stb>

Wont power up, red blinking light (on timer)

Refer to the trouble-shooting section of your manual. Usually, with this technology, the lights (Lamp/Temp) on these sets are also used at diagnosis/fault indicators... so, your manual should tell you what a flashing TIMER light represents. If the manual, doesn't provide this information, then ring JVC and ask one of their technicians.

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.

probably some cold solder joints. take your time and check over whole circuit board and re-solder what looks bad.
