Re: Lightning Damage

There are millions upon millions of electronics that could have been fried.  If you wanted to try and frankenstein with other broken receivers from ebay you might be able to fix it.   Also check to make sure there aren't any fuses and I recommend a surge protector.

I am looking for samsung Power-Supply signal board for model LA40B530P7R A

You will likely need a new tv. Changing the power board helps about 20% of the time. The other 80%, lightning skips into the antenna/tuner and knocks out those circuits as well.

Magnavox TB100MW9 DTV Converter repair

After a close-by lightning strike, my Magnavox TB100MW9
Digital TV Converter box stopped working. I took it apart and found a
shorted diode (the fat one on the power side of the board)
marked with the number SB340. From the NTE cross-reference
web site, I found a replacement diode, NTE586 (Si, Fast
Switching, Schottky Barrier Diode) that cost me $2.40 at
a local electronic parts store. I replaced the diode and
it works fine!

I would like a replacement router as this one keeps turning its self off up tofour times a dayp tivo

Are you certain that it's the router that's at fault? Is it wireless or wired? What about your wall power?: Does it fluctuate too much?

If wall power is the true culprit, you may find that a UPS ("Unlimited Power Supply") proves quite useful. Basically, a UPS is a sophisticated battery solution--the units incorporate powerful lead-acid batteries--the same type of batteries as those used for starting autos--merely smaller and less powerful.

A surge protector can't bump up power--a UPS may, though--it attempts to "smooth" current--putting less stress upon devices-- perhaps making them last better and longer.

In the event of a power emergency, UPSes may continue to power your TV/TiVo and your router/modem (perhaps located in another room). At least for a few minutes, you may be able to obtain news and weather. Given that your smartphone or tablet is dead, a UPS certainly may keep it alive. (UPSes do "beep" when running on battery power.)

I've noted at stores that your TiVo proves quite expensive. The UPS concept has been invoked widely--practically since the beginning--in business/enterprise, educational, and government computing. Thus, the UPS proves out now as a better home theater solution.

Where your router is, your modem likely is nearby: Plug it into a UPS, as well. Don't get rid of your surge-protector!: Those will remain useful. Certainly, you may plug it into a UPS--if you need more sockets. (Naturally, every such solution has its limits.)

UPS batteries likely will last several years: Generally, DIY replacement proves relatively easy. A great many online vendors service battery customers--replacement batteries at stores now are proving increasingly more available, too. Many differing "brands" often prove compatible.

One fault of a UPS: It's yet another "vampire current" in your home. When you leave your home or sleep, you may switch off the UPS--that ends that current drain. When leaving for vacation, you may then switch it off and unplug it--then, all connected devices are protected from lightning surges while you're away!

Lightning damage proves more common than most Americans believe. Nothing, save perhaps unplugging, can prevent damage from a direct lightning hit. In most circumstances, I do believe that a UPS will protect better then than surge protectors. My brother's TV was damaged by a lightning surge during a crazy weather event--he used a good surge protector, too: My stuff never has been damaged by lightning surges, though. I live nearby.

Needless to say, I've been a big fan of the UPS for a long time!

Did you have a power outage last night or lightning strike? If not unplug the receiver for approxiamately 30 seconds and plug it back in to the wall plate. Try to turn it on now. If it fails to power up it may indicate that the receptacle is bad or the receiver. Swap the plug from the receiver to the known good outlet the tv plugs into and try to power it up. If it fails the receiver is dead and you will need a new one. 510 are due to be discontinued with Dish so your local provider may not have one to replace yours with and you may be left with the option of upgrading the receiver, seeing if Customer Service can send you one out if you have a warranty program or buying one from a retailer or online.
Hope this helps you.
