Switching Off your TV in standby mode & power failure

When there is power failure, immediately switch off the switch supplying power to your TV. After restoration of power, there are incoming surges on the line which can damage your TV. It is also a good idea to switch off in standby mode. It consumes some energy & we may not know when there is power failure.

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

wont turn on but tries too come on,power light blinkink

Internal power supply failure. Was there a lightning storm in your area recently or utility work being done recently? This two things usually kill TV's and other electronics with surges when power is restored. If the set is under warranty call the manufacture, if not, call you homeowners insurance agent to see if the damage is covered w/or w.o. deductible. At least you can get something toward repair/replacement costs. Future fix, purchase and install a surge arrestor in your main AC panel for the whole house or buy a power strip with a built in surge filter/protector for your expensive equipment.

Had power surge. Tv was on surge protector. Now no power will come on and just makes a buzzing sound.

Have you tried plugging it in without the surge protector? I would wager that either a) the surge protector needs to be reset/turned on and off depending on the model or b) either your TV and/or surge protector have been damaged by the power surge.

Try plugging the TV straight into the outlet and see if that helps.

wont restart after power surge & verifying power supply restored

The control board may have been damaged by the power surge. You should install a surge protection device on the incoming power line, thereby protecting everything in the home from damage.

Have lcd tv samsung. Had a power surge now tv will turn on but no picture or sound. What could be the problem?.

If you get no standby light or error blinks, the power supply board is bad. Most likely the power surge will take out some capacitors on the power supply. Replace the power supply board to solve the problem. This is a common failure caused by a power surge.

Note: If you are looking to do it the cheap way, you could try looking for bad capacitors (visually inspect for ones that look "bubbly") and replacing just those but it is not guaranteed to fix the TV as the power supply could have other issues and just cause the capacitors to bubble again.
