Can reconnecting cable service kill a TV?

I have a 4 1/2 year-old Sony Bravia KDL-52W4100 LCD TV. I typically watch a couple of DVDs a week, but rarely watch television broadcasts. I hadn't used my cable service in over a month, and when I went to try it yesterday, I had no cable service. I called my provider (Comcast), who eventually told me that my account had been suspended because I had not used it in over a month. The Comcast rep sent out whatever signal was necessary to restore my service, and was successful in doing so. I watched a few minutes of a hockey game, then shut off the cable and TV. In the evening, I went to watch a DVD, and my TV would not power on. It was (and is) completely dead: nothing lighting up anywhere. I contacted Sony support, who put me through all the steps I had already tried (different outlet, resetting the power cables, etc.). Nothing doing. Completely dead. I have to wonder: Is this definitely a coincidence--first cable service is out, then it's on and TV dies--or is there some way in which restarting the cable service could have caused my TV to fail?

Well, I don't think this is the case. Reconnecting cable wire again an
again has nothing to do with the failure of the TV. Get some help of th
technician rather

A neighbour of mine had a new tv in the bedroom.

Did not use it for about a month, and all settings were lost.
Happens to be a "feature" of that tv, and you have to repeat the
factory setup for it again........ , or watch tv at least once a week.
(The tv was connected to the mains the whole period....)

The main thing is if you reconnected the physical cable or the cable
service.

On some equipment the chassis might be at half mains voltage (but low
current) due to a mains filter.

This could cause the input curcuitry to fail when you connect the
physical cable, if the cable is grounded somewhere. Or another tv could
ave a bad filter which puts voltage on the cable network.

But restoring the cable signal remotely should do no harm.

Then why wasn't the receiver already damaged?

No. While the cable company controls the cable box, there is no way a
control signal can arrive via a DVI or HDMI cable, from the cable box,
to the TV, and blow something up. The only remote possibility is that
the cable box applied some voltage to the +5v (50ma max) line on the
HDMI cable. That would hardly do any damage. All the other pins are
isolated and protected. Also, to the best of my limited knowledge,
there is no destruct command in the TV's remote instruction set, and
that Sony does not include a self-destruct feature.

The good news is that a totally dead TV usually means a power supply
problem. These are often a seperate board and can be easily replaced.
Usually, the problem is bluging electrolytic capacitors, which are
fairly easy to identify and replace. It is also possible that you may
have experienced an AC power glitch, which may have blown a fuse in
the TV. The bad news is that you'll need to contact a TV repair shop
in order to get it fixed.

Hmmm... there are some odd KDL-52W4100 boards for sale on eBay. Here's
a power supply:

There are several others for sale, but have someone diagnose the
problem down to at least the board level before spending money.

Yes, and the op does not indicate that the TV wss even disconnected from the cable at all.

ther eis a strange set of circumstances that can result in a failure when connecting to cable, but usually this is due to a gorund fault and sparks usually occur. There was no mention of disconnection and no mention of sparks, therefore I conclude the folowing : This is a bulb TV, they are about as reliable as a flea driven coast guard cutter, forget it. It failed on it's own.

In a CRT TV I would say there is a posssibility that it got kicked up into a higher scan mode and blew some sweep components, but this is a bulb TV. Some sets actually synchronize the lamp, but this is unlikely to cause a problem because there are no time constants. Plus the thing worked before.

If the set has been used otherwise, this is simp[ly a failure and has nothing to do with the connection or payment of the cable bill.

They probably wish they could break your TV remotely, but they cannot as of yet. Wait. They can disable cars and trucks now, and the almighty cellphone. just wait.

Big fucking deal. Consider yourself liberated from corporate Zionist

Yeah. Those "Big Valley" reruns on MeTV are really obnoxious.

Actually the Zionist controlled media made sure they caught the "Cartwright Curse" so there would be no sequels. They conspired to do this by putting them in adjacent or near adjacent time slots, possibly evn causing them to compete at times. The Cartwright curse seems to somewhat like athelete's foot, but it affects the whole body, and more drastically, causing death by gunfire in nearly every episode,m errr instance.
