I have a jvc jlc32bc3002 tv power on jvc come on screen but no rosta and picture


Try a hard reset to this set, and check. If it do not help you, a main board replacement is necessary. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Will not always power up, just clicks and power light flashes. Vertical retrace lines at top 2" of screen. Keeps shrinking and goes completely away after about 5 minutes.


The JVC sets are well known for this type of problem, the tv has a vertical deflection issue needs a few small parts and a touch up on the vertical ic, causes the set to shutdown. I recommend a tv technician for the repair.

Digital input not working and greyed out on the menu.


Most JVC TV's with HDMI and Digital Input have an optical sensor inside the case to sense if someone is trying to bypass the hardware encryption. My JVC was exposed to sunlight prolonged sunlight and triggered this optical sensor which disabled my HDMI ports. This may be the same situation for you.

JVC HDMI Port Fix

Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord. Reconnect the power cord, turn the TV on, and the HDMI port is re-enabled.


Here's how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.

JVC 36


Hi Dave: "My JVC 36" TV will not power on and has a blinking power light."

That means that the protection circuit has started because a fault had been detected.

If this happened after a power surge it is likely a faulty PSU board.

Try first leaving the set unplugged from power outlet for few hours, this will drain power, reset the protector, and fix problem related to accumulation of electrostatic charges on PSU power capacitors.

If unplugging does not work, that means that there is an internal fault.
If this happened after a power problem of some kind, that means that probably one of the capacitors on powr board had blown, and must be replaced.
The TV must be tested by a technician to find the fault.

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.

Big screen tv repair


There is a short in this TV set somewhere. The TV set is trying to come on but because of the short, the power supply shuts down. No if it is not the over current shutdown, it could also be the main power supply with an over voltage shutdown protection mode. These are solid state TV sets and should only be worked on by trained techs. Good Luck
