Question about Sanyo DS32830H 32" TV

Won't power on after local lightning strike

Lightning struck a tree 60 yds from the house. Several other items were toast. Possibly a voltage surge, maybe up through the ground, because the lights flickered on for a second. Usually, when you power on, a relay goes "thunk" inside and then the set comes on. Now nothing. When I pull the plug for a while, and re-plug it in, a tiny spark at the prongs shows current is going to the power supply, not to a blown fuse in the power supply. I took the back off carefully, and blew it off, then checked the barrel type fuse where the power cord is attached. It was good. I have a voltmeter, and can identify some basic things on the board. A technician said it's probably the power supply (duh) but I can't tell if it is mixed in with all the rest on the board, or separate and hid in with the buttons on the case. I'm willing to solder in a new transformer or capacitor if I can isolate the problem. It's only 2 years old, and I really want to keep it, but a service guy costs as much as new set. Please help!

Both of my tv's died yesterday. My apex wont turn on anymore an the panasonic has no picture. Whats wrong.

As an electrician, when someone loses more then 1 item of electronics in 1 day, its almost
always traceable to a nearby lightning strike, accompanied by a lack of surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360. Surge protection can
be provided by the consumer at the power strip (a good one with builtin protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house protection, or per-circuit protection at
the breaker box, where a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed), other than renters insurance or homeowners insurance.
If desperate, you could try replacing the entire power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Got a 47 inch flat screen sanyo. tv will power on get a picture for about 10 sec and then turn off. transformer outside of house was struck by lightning

Sound like you had a power surge that has taken out the invertoer power supply capacitors...these are electrolytic capacitors that will be taken out by surges(it's a veryu common problem) can take the cover off the back and look for the power supply board(it will be the one with the ac line cord going to it...look at the cylindrical components on the board to see if they look bloated of have some fluid leaking out of them..this would indicate a bad capacitor...if you don't want to take the unit apart you can take to a shop and have them look at it...note: If you own your home and you have homeowners should cover the tv if you had a close lightning strike...just a suggestion

27r410t no power

did you check that you are receiving a good hot (a consistent 110 ac) check the tv on a different outlet otherwise the chassis board has malfunctioned inside the tv. Probaly the flyback transformer which converts the 110 ac to thousands of volts to power the CRT (picture tube) which has failed more than likely. Usually the culprit after sustaining a surge from a lightning strike. Not worth the repair just replace go to your local pawn shop for a great deal on another used tv

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.

Sony KV-20FV12 channel will not change

Pasted from another message I just posted-

It may be too late for this advice, but if you live in a lightning prone area, you should consider having a 'whole house surge protector' installed.
The cost should be well under $300 (a lot less if you install it) and with the included insurance (most often for $25,000) it is a good investment.

If your house was struck, I'm surprised you don't have a list of things that no longer work.
No, I don't think it is worth the cost of a repair, if you can even find someone to do it for you.
Most of us are retired-

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.

TV was struck by lightning

If it was struck by lightning, the surge would completely fry the insides of your TV. Your TV probably won't work anymore and you may have to consider replacing it. Some TVs have accident warranties so something like this could be protected, but if not, you will have to purchase a new one.

Lightning Strike?

Assuming this line is across the screen horizontally (side to side), this means the vertical deflection circuitry is dead. In late model sets, there is a Integrated circuit package which drives the vertical yoke coils. Possible defects: the I.C. itself, bad solder connections where it solders to the board, missing voltage source to this I.C. (often around +24 volts), or a bad electrolytic capacitor in the associated circuitry. This latter often results in a non-linear picture, or less than full deflection condition, rather than a thin line only. It is possible lightning caused this problem, (I've seen some rather illogical damage from lightning ) perhaps it produced enough of a surge to pop the I.C. or a fusible resistor in that voltage source noted above.
