    The TV was NOT on. Yes, it was plugged in. Yes, cable TV coax was connected. I suspect standby circuitry damage, but don't have schematic/wiring diagram to locate components. I have a Diode, Transistor/FET tester (in or out of circuit) and am checking any and all transistors/FET's I'm wondering if the large IC chip was 'zapped' (8812CSDNG5JB4 - TOSHIBA, Main Board) or the Tuner Board IC, (TA1218AN - TOSHIBA). The main board fuse is intact (no damage). Have checked components on front panel circuit board - no problems found. I know lightening strikes are unpredictable and can wreak havoc in electronic circuits (especially IC's). Four TV's in the house were also plugged in, three w/cable TV coax connected, one of which was 'ON' when the lightening struck, only the JVC set was affected (which was also OFF). Other electronic appliances/equipment were also affected (printer, wireless router, digital clock/radio/phone, cordless phone, etc.) If you have a copy of the schematics for the JVC AV-32F476, would you e-mail them to me?

    Thanks.

    Was the unit ON when the lightning striked?

    If it was not on, was it plugged to the wall?

    Does it have a cable tv connection?



    Lightning damage is unpredictable...frontend or power supply circuitry...might be worse. Better have it checked with an expert technician to asses the damage or else ditch it for good instead of spending unnecessary costs.

Sorry, I don't have a schematic diagram for your unit.
I guess the lightning path zeroed-in to your JVC tv. Goodluck anyway!

First, you will want to determine where exactly did the lightning go through. It could have came from the power cord, or it could have been your cable/satellite. To do this, unplug your TV and open it up. check the inputs for the power source as well as cables. Follow where the cables go and check the nearby components. See if anything is visually broken, burned, or fried. Chances are decent that there are going to be some blown components that you can visually see.

At this point you need to determine the damage. it could be as simple as a couple blown fuses. if you are able, test the different components and determine what needs to be replaced. if its easier you could see if you can replace the fried board itself. Generally there are multiple circuit boards inside a tv. there will be one for your power supply, an inverter board as well as others.

Its really hard to tell what exactly is broken without actually seeing it TV, and there is a chance that its just time to buy a new TV.

Lastly, if you don't have experience with electronic components or feel uncomfortable opening up and messing with your TV, take it into a good shop and see if they can diagnose/fix the problem. It can get expensive but a lot of the time its cheaper than buying a new TV.

Hope I helped

What is the likely culprit to troubleshoot on a tv that will not power on and there is no standby light after a lightening strike in the area and fried Directv recievers and tvs?


Hi , it sounds as if the av board is probably fried but it probably did not stop there it may not be worth getting it checked out as that's just another bill to tell you its not worth repairing. Take time to think about it. But get it checked if you wish there is a lot of power in a lightning strike. It could fry one board and pass through the next as they are usually connected.

Hi my recently we had a lightnight strike


Hi Kayal,
This kind of problems occur after lightening. I am sorry you can not do anything about it yourself. You will have to consult a good local TV Tech.

Sony bravia lcd won't power on after lightning strike


I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.

My dynex tv wont turn on! the strom knocked out our power, now the power is back on the tv wont turn on from remote or tv power button.


Lightning is a weird beast, and can do strange things to a TV. Sounds like the set took a hit. If there is a fuse then check it on a volt-ohm meter for continuity while it is out of the circuit, and if it is an open circuit, replace it. If there is a circuit breaker, then reset it. If these don't work, look for obvious scorching on the circuit board (assuming you know how to avoid electricution, otherwise do not touch). Lightening can literally jump around on a circuit board, so there is no way to know what part of the set was effected by the strike - the lightening will not always burn out the first circuit it touches, but will burn out something further into the circuit. The most obvious place to look is around the transformer and rectifier circuits. If a capacitor was hit, it may be swolen or discolored; resistors will scorch, and the worst thing is that transistors and IC's often show no damage - in fact, any part might be burned out and not show visible signs. If nothing is obvious (like scorch marks) and the fusing is intact, there are too many possibilities to begin listing them all. The fact that it won't turn on at all sounds like it is probably a power circuit, but, not necessarily. FYI turning a set off during a lightning storm does not protect it, you have to unplug the AC power cord and the line that feeds the signal into the set. Even circuit protection devices (lightning arrestors) may not protect against a close strike. Maybe the techs at Best Buy can supply more suggestions (Dynex is their brand).

Tv won't switch to "tv"


Your T.V. is programmed to store the last input you've selected. You have to manually switch it back to your T.V. channel input after each time you switch it to HDMI or any other input even when you turn it off. The "Source" or "Input" button on your original T.V. remote will change this.

Bad storm, lightening strike outside then TV went off and will not come back on.


I would start with your power supply. If you took a surge it is possible that you only blew a fuse. If it is a blown fuse, make sure you only use the same type fuse.

The cable guy programmed the cable remote to turn on/off the TV. We used it to turn the TV to stand-by. Then pushed the power button on the TV to turn the power off. Haven't been able to turn the TV on...


First use the original remote control that came with your tv, or just manually turn it on at the tv itself to bes sure it is working. If it works you should call the tech support for the cable company to program their remote control to a different code - or put it back to to factory state and just use two remotes.

Tv hooked to cable system and next door neighbor had a lightening strike. After that, the tv does not work any longer--no power light at all.!


Your TV got fried when the lightning struck. Time to get another one.

This time be sure you plug it into a surge protector power bar, available at radio shack, walmart, any TV or computer store.
