Thunder storms have rolled through tonight. There was a loud crash that shook the house and an alarm clock came on on it's own. I didn't think much more of it till I went to turn a TV on and it was just a blue screen with no HDMI signal. I tried switching to DVD. Wouldn't pick that up either. I know squat about the internals of a TV, but I'm guessing the video board is screwed up. I went to check the smart TV in the living room. It's standby light is on, but it won't come on. Then I went to the garage and found that the TV out there won't turn on and has no standby light on. I don't really care about the garage TV. It's old and I really haven't used it for quite some time. All were connected to surge protectors, none were on at the time, but I guess a surge can pass through coax to the cable box and to HDMI or the surge protectors just weren't good enough.  |

I wouldn't mention the storm though. It's an 'act of god'.

That sucks, If you are not receiving any signals thru any of the inputs(coax, hdmi, component) chances are the input board took the hit. If it's powering up and a blue screen, that's a good sign.  Nice part, this stuff is "modular" and hopefully parts are still available to fix. As for your other TV's, gonna guess power supply or logic board, or maybe a fuse. Id do an insurance claim and get ya some new tv's. Not many surge protector can stand up to mother nature, if lightning can travel miles thru the air without conductors, traces on a circuit board that are less than a 1/32 of a inch apart are not much of a challenge. |

Wow all three. You'd think that with differently designed circuitry maybe one would survive. A good technician familiar with certain brands may be privy to parts that are likely weakened by hv spikes because sometimes even replacing the bad parts only lasts for a short time until the weakened parts fail. Two trips to the repair shop may not be justifiable over replacement.
Of course surge protection is available for signal lines. But, on the other hand, not all surge protectors are as protective to equal extents.

As gsx600racer said you might be able to troubleshoot off the web and find a full board on eBay or something if insurance fails to satisfy.

I have surge protectors that will run coax through them, but when I do that the cable doesn't work. I'll have to see if there are different ones hat will actually work with digital cable. |

I've heard of routers not on surge protectors passing surges through Ethernet cables and destroying compupters.

I was lucky with the PC. I was online when it happened, because there was distant thunder here and there. Didn't expect a sudden close strike. It's hooked to a Monster surge protector, but I think the cable boxes passes on the power from coax.
There was one TV that didn't blow up in a bedroom. I hooked it to the HDMI in the living room and when I switched to HDMI the TV went off. I unplugged the power cord and the standby light was still on. Unplugged HDMI and it went off. That TV will turn on with no HDMI connected to it at least. Not so lucky with the bigger better TV. It's standby light now doesn't come on at all. Gotta contact Comcast today and swap out boxes.

Went to call comcast since their chat wasn't working and no phones work in the house. Called on the cell and they aren't going to let me swap out a box. Gotta send a tech and that will be late tomorrow. He'll prob call the home phone to verify and then not show up since I can't answer. That or not even try. My last 2 scheduled appointments with them, no one showed. I called about it both time and both times they told me I had no appointment. Makes me curse out loud every time I see some BS Comcast cares commercial. If the tech does show up, then with my luck he'll say he can't do much without a working TV try the boxes.

I've only looked at one TV so far; the one that won't turn on at all. I don't seem to get standby voltage at the end of the power supply board. I have continuity across the fuse. The board is about $40 and the main board is more like $100 if I can find one to match it. I'm a bit worried that the main board may be bad since that's where HDMI comes in, but for $40 for a TV that's $400-500 to replace, I think it's worth the risk there. Nothing is gonna go through H.O. insurance. We've got a $500 deductible, and I don't know exactly what I'll be spending yet. Not worth the risk of premiums increasing over a small claim to me. One TV was a Black Friday deal at $430 IIRC, my 60" was $950 7 years ago, my parents won one for a $2 raffle ticket when they ate at Golden Corral last year, and I don't care about the garage TV. I can't see risking a rate increase over that. If the phone section of the modem is fried, then I'll probably rent the next one from comcast so they can replace it if it goes up. It paid to buy our old internet only modem that was $100 and lasted nearly 10 years, but the VOIP + internet Arris was about $250 IIRC and it's lasted 2 years or so. Getting near the break even point. I can always buy one later and turn comcast's modem in if I change my mind on that anyway. EDIT : The 60" I think ruined the HDMI inputs on the main board. I went to try a new HDMI cable and sparks went from the cable to the TV so the comcast box is zapping stuff.  It works in with the coax connection, but not HD and the box only has HDMI and coax outputs, plus no DVD or anything else will work. The main board is a big piece, and by the time it's shipped, about $200. I think it will be replaced with something smaller and LED. Being DLP I don't want to end up with another lamp failure or other issues associated with DLP after it's fixed. |
