Power surge during lightning storm, Surge protector didn't help. Now my TV wont turn on nor does it have any flashing lights. I believe the power supply board has power running through it though because I checked it with a multimeter. How can I troubleshoot the other boards or could there still be something wrong with the power supply even if I have a reading?
SOURCE: Someone please help
Good Day;
Two things normally happens after a L storm:1.) One must unplug TV for 5 minutes, then plug back in. 2.) Main glass fuse out, will be near a/c cord. 3.( Power regulator IC may be out. Try these first.
Good Luck!

one of the first things that go are is the protection diode coming off the + input. Then a fuse and so on. Surface mount fuses are light in color (usially green with white text). Attempt to bypass these components with a small wire or paperclip. Once you follow the lead from positive input you will run into a black rectangular block about the size of a grain of rice with 3 leads. That will be your voltage regulator. Its set at the correct voltage, and since you already have a power supply with a set voltage, then you dont need it. Its also the first thing that blows when you switch polaritys. (voltage regulators have 3 pins - input output and ground) when you switch polaritys that ground becomes the "input" and ..... go to all http://www.alldatasheet.com/ and type in the text you see on that component. It will then identify the component and list its voltage output and at which pin. Apply set voltage to lead and ... pray?
Best of luck.

The warranty does not cover lightning, check if your insurance covers it.
A lightning strike on such panel ( HDMI ) is very difficult to repair and if not impossible.The HDMI connector is hooked to the ground of the TV set so everything could be damaged.
My advice is not to repair.

Hello:
U just may of blown fuses on the power supply of the television if you are sure it was a surge. If u can open the unit check all fuses on the power supply for open coniditions. If the future is a good Ideal to use a surge proctector as this will protect your equipment. Make sure power is off and remove AC power to check fuses. Sometimes just removing AC power for a least 2mins will reset the unit.
