Question about Televison & Video

1 Answer

Lightning struck the cable tv line coming into the house. All of the electronics connected to the cable quit working. I took the back off of one of the tvs, and could not find any sign of scotch, burn, or any type of damage. The tvs simply won't come on.

A lot of electronic devices have built-in on-board surge suppressors such as MOV's, and avalanche diodes - these could get damaged during a lightning strike. Fuses are another possibility. Beyond that, gotta take out your DMM and oscilloscope and start troubleshooting, or see a technician.

Xerox phaser 3100mfp printer it was struck by lightning and the power went off. I took it in the was restored but, now it does not print the page comes out all black without any trace of printing

Power Surges are really tough to trace down. Sometimes more than one component can be affected. And what funny after the surge an electronic device may work fine an then a year later quit due to the surge had weakened the unit. Most insurance companies realize this. My home was struck I have a 2 year window to take items in to be checked and if it's found a surge was to blame it will be covered. So far 5 electronic switches ( 2 immediately 3 others have failed over the past several months and 1 DW touch panel and 8 months later my TV had 8 caps blown on the power supply. Hope I helped on why an item may have issues later. best to you

Jvc model no. LT-32p679. cable line was struck by lightning now tv wont turn on

Cable system is grounded to electrical system. Most electronics have fuses inside. Open it up and look for blown fuse.

Open the television and follow the power cord to the main power supply board the fuse will be near this cords contact plug check for blown 5amp fuse, if fuse is not blown then power supply took a shock and needs repair.

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.

Lightning struck outside our house last night. Air does not work. Unit outside does but the thermostat smelled like the wires were melting. Husband got a new thermostat but we can't get the unit to come...

lightning is in KVolt range, the exterior unit is most likely damaged at the low voltage cables to the thermostat, melted out, should get a sparky in to trace the lowV lines, and check out the unit, lightning is not forgiving

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.

Lightning hit last night tv won't work cable company says it's in the television

Sorry to here about your problem! This is the time of year I used to get tons and tons of sets, stereos ,games, and vcrs in for repair. On your panasonic it seems that maybe the surge took out the tuner portion or the power supply. It sould cost aprox. 200 bucks or so for a new tuner. Im sure your aware that homeowners will cover almost all repair after the deductable. Good Luck
