Sanyo 24" TV

I had a lightning strike which fried 5 TVs back in June, When I took them to be repaired, 3 were deemed not reparable and 2 Sanyo TVs were repaired by the repairman, One is doing fine and has worked ever since. The other was supposedly repaired but when I brought it home it stayed on only a few minutes and then switched itself off. IT could not be turned back on until I waited several minutes. then I could get it back on but only for a limited time ranging from 3 to 45 minutes. I have had it back to the repairman at least five times. He says it works perfectly at his place and he sent it to a factory authorized repair place and they had it on for a week and said it worked perfectly. I called the power company and they checked the voltage and everything leading into my house.I then called in an electrician and had him check all the outlets in the house. they all checked out normal.While it is on,the picture is perfect and the sound is perfect.The electrician installed a new surge protector on the power panel when he was here. We have tried taking it to our neighbor's home where the same problem occured.We love the TV and would certainly want to have it back as it was before the lightning strike.

Re: Sanyo 24" TV

As you say that tv works fine at the place of tv tech so it sounds me that you please tell electrician to check for ground connectionat your house. if it is ok then in future you will not any problem.

Lightning strike, blows internal fuse (6.3v 125/250) on plug in.

sounds like the lightning strike took out at least the power supply if not more. sorry to be bearer of bad news.

This morning I tried to turn my RCA TV (model 24R411T) on and nothing happened. I tried plugging it into a different outlet, still nothing. I tried leaving it unplugged about 10 minutes and trying again,...


Power surges or nearby lightning strikes can destroy electronic equipment. However, most of the time, damage is minimal or at least easily repaired. With a direct hit, you may not recognize what is left of it!

Ideally, electronic equipment should be unplugged (both AC line and phone line!) during electrical storms if possible. Modern TVs, VCRs, microwave ovens, and even stereo equipment is particularly susceptible to lightning and surge damage because some parts of the circuitry are always alive and therefore have a connection to the AC line. Telephones, modems, and faxes are directly connected to the phone lines. Better designs include filtering and surge suppression components built in. With a near-miss, the only thing that may happen is for the internal fuse to blow or for the microcontroller to go bonkers and just require power cycling. There is no possible protection against a direct strike. However, devices with power switches that totally break the line connection are more robust since it takes much more voltage to jump the gap in the switch than to fry electronic parts. Monitors and TVs may also have their CRTs magnetized due to the electromagnetic fields associated with a lightning strike - similar but on a smaller scale to the EMP of a nuclear detonation.

Was the TV operating or on standby at the time? If it was switched off using an actual power switch (not a logic pushbutton or the remote control), then either a component in front of the switch has blown, the surge was enough to jump the gap between the switch contacts, or it was just a coincidence (yeh, right).

If the TV was operating or on standby or has no actual power switch, then a number of parts could be fried.

TVs usually have their own internal surge protection devices like MOVs (Metal Oxide Varistors) after the fuse. So it is possible that all that is wrong is that the line fuse has blown. Remove the cover (unplug it first!) and start at the line cord. If you find a blown fuse, remove it and measure across the in-board side of fuse holder and the other (should be the neutral) side of the line. The ohmmeter reading should be fairly high - well certainly not less than 100 ohms - in at least one direction. You may need to unplug the degaussing coil to get a reasonable reading as its resistance may be 25 or 30 ohms. If the reading is really low, there are other problems. If the resistance checks out, replace the fuse and try powering the TV. There will be 3 possibilities:

It will work fine, problem solved.

It will immediately blow the fuse. This means there is at least one component shorted - possibilities include an MOV, line rectifiers, main filter cap, regulator transistor, horizontal output transistor, etc. You will need to check with your ohmmeter for shorted semiconductors. Remove any that are suspect and see of the fuse now survives (use the series light bulb to cut your losses - see the section.

It will not work properly or appear dead. This could mean there are open fusable resistors other defective parts in the power supply or elsewhere. In this case further testing will be required and at some point you may need the schematic.

We had a near lightning strike and now my tv (sanyo model ht27744)doesn't want to come on.

Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.

Sanyo 25" TV struck by lightning - where do I begin?

Not to different from arcade, If the fuse is blowing right away check the bridge rectifiers next for shorts and anything on the primary ac to dc side first, Caps,may have a surge suppressor on the ac side. If it was lightning sure you will find it in this area. Secondary supply shorts usualy do not blow fuses, Just cause the supply to shutdown.

depending on the intensity of the lightning strike.Your tv may have blown components in the power supply section of the motherboard.
unfortunately its very very difficult to acertain level of damage unless its looked at by a trained tech/engineer

Lightning strike

I have the same tv, but the problem I have is the picture is shifted to the right and can not correct it. At 1700, its probably not worth fixing because to expensive to repair, they dont make it anymore
