Question about JVC AV-36D302 36" TV

1 Answer

TV DEAD My TV stopped working after an electrical storm. The breaker did not kick off. I looked in my manual and the power light is blinking and the manual says take for repair. The darn thing is so heavy I cant move it so an inhouse service call is the only solution. My brother sais his JVC did this and its in Sleep mode but I can power up anything so no way to correct - Any Suggestions?

No not sleep mode as in sleep mode it only will turn off power and when the power goes out the sleep mode resets. your problem is most likly in the standby power supply or maybe even in the main supply. If you know how to use a multimeter and about the powersupply circuitry in these sets you should be able to find the fault. If you havent a clue where bto start a tv set is not a place to be experimenting around inside of. Have it looked at by a trained tech

Tv won't come on

Does the outlet still work? The storm may have tripped the circuit breaker for that outlet only.
Another option is there was a surge of power and you weren't using a surge protector. That can overload a capacitor and you will need to get a technician to fix it

Tv turns on but no picture or sound, power light blinking

How many blinks does the light do? Or is it constant?

Toshiba cz32v51power light flashes, with no picture

That means that an internal error had been detected, and now the TV is on protection mode.

To start unplug the power cord for ten minutes, and see if the TV restart.

If it does not try leaving the set unplugged for longer, let say two hours.

If still no luck call the number listed on the user manual, as the TV has an internal fault, and must be repaired by a technician.

TV won't turn on

The set is in protective shutdown because a problem was detected. The 5 blink code indicates that the problem circuit. In this case it is the blanking circuit. Were there any indications of problems prior to the storm? If not, I'll need to lok up this one for the specifics. Do you intend to repair this yourself?

Let me know and I'll provide the details.

TV won't turn on

The 9 blinks usually mean that the power regulators are shot. This is a relatively simple repair and is a wear and tear item. Expect about $25-$35 in parts plus the local labor rate for the total repair cost. If you want to try and repair it your self, I can look up the part designations and numbers.
Keep me posted.

Blinking light wont turn on Toshiba TV CE19H15

Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.
