Hi.

Try first disconnecting the power cord for ten minutes.

If that does not reset the display, please give us the complete model number , so that we can provide more help.

Thanks.

    I think that is the parental lock a timer allowing use of the TV only at determined times (or never) had been programmed by mistake.




    Let me find technical documentation for this model, and I will get back to you.

    Hi.




    I was reading both user manual and service manual.




    This model does not has parental lock, and the function that had caused the TV to freeze is the on/off timer.




    The on/off timer is started using the Timer button on the original remote. As far as I know , and according to the manual, the on/off timer should also be reset when there is power surge.




    For this reason I think that rather than be stuck in timer mode, this TV may be reporting a fault. As specified on the manual, the timer light blinking means that the TV is stuck on protect mode, because a fault had been detected.




    You can read more on protect mode and on basic troubleshooting here.






    When the TV is on protect mode, it must be tested and repaired by a technician.




    If you want to repair the TV, the best thing to do is contacting JVC. If the TV does not get out of protect mode, then the unit must be tested at component level by a technician.




    Here the user manual.






    Here JVC contacts:

    What I mean is: if the on off timer button does not unlock the TV, and if disconnecting the TV does not reset the On Timer light, that means that the TV is on protect because an internal component had blow.




    In that case you need a tech testing PSU, alignment circuits, flyback transformer etc.

Lost manual. Cannot get HR A591U JVC VCR program to record a future cable tv program. Seems I have tried everything but it does not record as I set up. It will record an existing show by pressing...


Timer Recording JVC VCR HR A591U
Timer recording can be programmed on-screen with
the remote control. The built-in timer allows automatic
unattended recording of up to 8 programs within 1
month.

EXAMPLE: Program a timer recording for the 26th day,
channel 125 (CATV), 11:00 - 11:30 PM on timer program
number 1 (Tape speed: EP).

When a TV is connected with an audio/video cable, turn the
TV and this VCR on and select the video input mode on the
TV.


• After timer recording is completed, the VCR turns off
automatically.
• You can program the timer recording while a regular
recording is in progress; the menu screens will not be
recorded.
• The timer recording will start at 20 seconds before the time
you predetermined.

Press MENU on the Remote.
Check the “TIMER REC SET”
option is selected, then press
ENTER.

Press SET –/+ to select one of
the program lines, then press
ENTER.

Press SET –/+ to select the
date, then press ENTER.

Set the start time, end time,
channel and tape speed as in
step 3.
NOTE: To record from external
source, press SET –/+
and set the channel to
"L". "L" will appear next
to CH 125 (or 69).

To enter other programs,
repeat step 2 through 4. Or,
press MENU twice to return
to the normal screen.

Press TIMER on the Remote.
The power will go off, the
TIMER REC indicator ( ) will
light and the VCR stands by
for recording.

To cancel a program:

Press the SET –/+ to select the
“TIMER REC SET” option in the
MENU. Then press SET –/+ to
select the unnecessary program,
and press CANCEL to cancel the
program.

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.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

I will keep you posted when the guy will return.

JVC tv i'art blinking timer


It is protecting you and itself with high probability.
Power supplies in modern electronic devices are designed to cycle if there is a fault in circuitry they are servicing and because of the design, also will not turn on completely if they are failing.

The older style of power supply was 'dumb' and unable to do this so could cause fires if the failure wasn't teh 'right' kind to blow the main fuse.

I agree with the manual; this is a job for a tech.

JVC tv "stuck" on sleep timer


I think you would have to turn off the sleep timer mode completely or increase its ON time span, say to 4 hours or so
or the lenth of time you have the TV on for. If that does not fix it then it sounds like a STANDBY MODE fault problem.
Hope this helps.
