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.

I have a Samsung Plasma tv (PN59D8000FFXZA) that after my neighbors house was struck by lightning it won't turn on. What steps should I take for diagnosing the root issue?


When it get hit with any surge usually the main Board is gone, to replace it and hope nothing else is wrong, you can get a 4k LED for probably same price

Lightning struck my house and my tv went out I think it blew something in it like the circuit board are ther more than one board in these tv


If the power light doesn't come on then first look for a fuse. It's very likely a fuse. If all fuses are good and power comes on you might have lost a circuit board. Check eBay for boards. Part numbers are printed on them. They just unscrew and unplug. However it could be either board.

Need a downloadable manual for this piece. Lightning struck house now have a fried part...


What model TV is it from ? The Powers Supply schematics are usually found in the TV service manuals. The information in the service manuals is very limited and you most likely won't be able to get a full schematic of the PS.
Alternativly buy a replacement board. They seem to be widely available.

It may be the cost effective answer as service manuals are quite often, not cheap.

Tv struck by lightning


You wont be able to fix the TV your self as the power circuit board may have blown - consult a qualified repair man. Buying a surge protector for your expensive electronic goods is highly recommended.

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


The typical power input involves a small line filter, fuse, inrush current limiting resistor (1.2 - 2.8 ohms) rectifier bridge, filter capacitor(s) and a 120 volt regulator. All located quite close to where the power cord connects. If there is one diode shorted in the bridge, replace all four if they are discrete. The fuse and the resistor may both be open, depending on the level of damage. Make sure the input and output of the regulator are not shorted together. Even if you get the set to come to life, the tuner may be toast, as the antenna connection and power line serve to be the entrance and exit paths for the damaging energy. Respect the high-voltage section in the TV just as you do with the monitors.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

LIGHTENING STRIKE


Ed,
Open the back and take a look at the saw tooth filter cap. It's the largest cap you'll encounter in the PS. Just follow the electrical cord onto the board and look for a VERY large electrolytic cap in that area. Usually they bow at the top on a strike like that. Replacing the cap might restore the unit.
If not do you have an esr meter?
