Re: Possible lightening strike

Lightning will create a lot more damage,the vertical circuit has become defective,the repair should not be expensive better be safe and call a qualified technician.

I have a Toshiba 27AF43 27 inch television that no longer powers on at all. We had a lightning strike right next to our house and it tripped our breaker box. When I flipped it back on all other electronics...

Lightening does a LOT of damage, I wouldn`t have it repaired and I`d contact my house insurance immediately. I`ve repaired lightening damaged sets before only to find that the set only lasts a short period before different fault appears and once you make a claim on the insurance for a repair, they won`t pay out again for another repair on the same set. The problem you`ve got is when the lightening hit the power line, it sent a transient or high voltage pulse through your power lines. The computer and a lot of the other circuits in your set only run at about 5 volts. If your TV power is normally 240 volts like ours is and the transient pulse rises 1,000%, (In practice a lot higher than this) in effect the power lines in your home will have risen momentarily to 2,640 volts. This means that the other voltages in the set will have risen proportionally with the input voltage meaning that the 5 volt lines will have risen to 55 volts which would either destroy the circuits on that line or as you will find out later if you have the set repaired, weaken the circuits which may survive for a short period until you`re sat down watching your favorite TV program and one of these components decide to give up. Take my advice and claim for a replacement set, You`ve been warned. Ian

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.

"zapped" tv (dee7189)

I would need more details on this problem. Does the tv turn on? If so, what do you see on the screen? If you mean by "zapped" that the tv received a lightning strike and does not turn on, it's possible there are several damaged circuit board components. Depending on the severity of the strike, it's possible that just the fuse is blown. I need more details to advise further.

yes ligthning damage your unit because of static electricity that increase the power of your power source

Color line across the center of a black screen

Hi. this is caused by dry solder joints on the frame o/p IC. Resolder all legs of frame chip. Should sort that out.

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.

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
