Sharp LC-32D59U does nothing after loss of power due to storm

[Ow5856ba]

So I'm assuming after a recent storm and hearing a loud pop as we lost power for 8 hours I'm guessing it had a good surge go through it. My internet modem and router and also my CCTV DVR all no longer work, and we're on same power strip. Which I don't think the surge protector was any good on anymore.
Anyways it does not turn on or do anything anymore. I looked at all the boards and nothing looks melted or burnt or anything. The fuses look like they could of blown I'm not very good with this electrical stuff but my boyfriend is. And I just need help on how to figure out what's wrong with it and how to go about it

EWWWW...... I hate these situations. Lightning strikes are hard to diagnose and fix - Assuming that's what it was. Electricity has a mind of it's own once it gets high enough. It still follows the basic principles however, it will overpower the common designs that we create to channel the electron flow. Those power strips hardly catch the surge that a storm can create. They wont shut down fast enough. The only way to truly protect equipment from lightning strikes is to unplug.

You can check the internal fuses. If you are able to find something blown and replace it and get one of the things working, great. My only concern is that sometimes other components are stressed toward their tolerances that the unit may not last long anyway before something else dies. Replace all with craigslist finds - much cheaper and less frustrating. - Just my opinion.

It may have blown the 4 fuses, There are 4 mov's that that may have protected the power supply, they will need to be checked also. see this thread https://www.badcaps.net/forum/showthread.php?t=37834

How about showing us good clear pictures of the boards?

What inputs were you using with the tv (HDMI, etc)? Hopefully the surge didn't go though the ports and fry the main board. I've had a couple of TVs with fried main boards, (Vizios and some Panasonics) following with a fried cable box that doesn't work anymore.

Whenever there's a storm now, I tend to unplugged the main tv I use from any power just as a safety precaution =).

I will get pictures up tonight. And I think fuses are blown. I had a VGA cord hooked up to tv that was for my DVR for my camera, my ps3 hooked up through hdmi cord.mi believe the tv was off at the time of the lighting strike but there was loud popping noise and we didn't have power for The entire night after that

For inquiring minds, you unplug your tv and anything connected to it correct? Unplugging just the tv would just make the tv more prone to damage if a device connected to it takes a hit. Considering you have removed the tv's earth ground.

I know no UPS or surge bad will protect from the massive serge a direct lightning hit will produce, but i dont run any TV with out a UPS. A good UPS will at least ensure any over or under voltage is not hitting the tv, with in moderation of course.

Here is the ac input circuit

I usually unplug any inputs on it, especially the HDMI inputs (Just had a storm here today too). I'm okay with leaving the power connected. I would rather repair a struck power supply than deal with a fried main board (which usually shorts the main processor and would require a new replacement afterwards...) Some Sony panels have an energy saving switch that disconnects the AC power to save energy.
