  3. TV's suddenly turn off in same setup. Why?

TV's suddenly turn off in same setup. Why?

Two TV's "died" in same setup. What happened?

1) Mitsubishi CRT TV made in 2000, it was on continuously about 8 hours a day for almost 6 years.

The TV power cable is plugged into the power outlet of a cable TV box. Standby power was always on on the TV, and the cable TV remote is used to control the box power and the TV power.

RCA cables run to a DVD player, a VCR, a CF card reader, a computer, Playstation and Selector box. And a UHF/VHF coaxial cable runs from the cable box into the TV.

While watching TV, suddenly, the TV screen went red and it turned off. Pushing the power button on the TV turned it on for a second and it would go off. Repeated this many times. Comes on, goes off, sometimes doesn't come on.

When it's on, banging the side of the TV makes the screen go red and it turns off with an alien kind of buzz sound.

When it's on, removing the RCA or coaxial cable at the back of the TV makes it go off.

So...

2) I setup an Aiwa CRT TV made in 2001, with very few on-hours on it.

I only attached an RCA cable from the cable box into the TV and the coaxial UHF/VHF from the cable box into the TV. And I plugged the TV power cable into the power outlet of the cable box.

The TV worked fine for 4-5 hours. It was on standby power overnight. The next day worked fine for an hour or 2 and then, suddenly turned off! Doing the power button same as above but no luck. Sometimes it comes on, etc. Banging the TV medium-hard makes it go off.

From this point, I disconnected the RCA cable UHF/VHF cable and

plugged this TV into a wall outlet away from the present setup.

Waiting a little while seems to revive it and then it goes off again, or shaking/banging it makes it go off with a white flash like lightning on the screen.

The Mitsubishi had only "normal" heat from being on.

The Aiwa didn't even get hot from being turned on when it was working before suddenly going off. For both TV's, no smoke, no blackened areas anywhere, no smells from any of the equipment listed above.

Who would I contact to check the other units that were connected to the TV for wiring issues or power surges or whatever?

Why was a rubber mallet a standard issue tool for all the test techs at R.L. Drake? Why did Microdyne have a six inch drop test on their brand new 700 series Telemetry receivers after full power burn-in? To see if there were problems with intermittents.

Hi, it is I, yattaman.

I banged on the TV because...isn't that what you're supposed to do as a last resort?

Now, seriously, is there a "short" somewhere in the setup? Are these two TV's salvageable? Dare I connect a third TV here??

Because they have an error code 'ID ten T'

Scroll down......

Translated 'ID10T'

There's a bad solder connection (most likely), loose connector or connector that needs to be cleaned and reseated, or something along those lines.

Because it's actually an excellent diagnostic tool to confirm that an intermittent problem is due to a bad connection (as long as you don't get too carried away!).

If you have any possible reasons why this happened to _two_ TV's, one following the other, setup in the manner I described, please tell me.

It's obviously got some cracked solder joints in it if banging makes any difference. Quit trying to turn it on until that simple problem has been fixed or you'll cause more damage and it probably won't be worth fixing.

Coincidence, pure and simple. Power surges and shorts don't cause cracked solder joints, design or manufacturing flaws do. It's the root cause of probably 80% of TV failures, it's no surprise at all that two of them failed of the same thing, one well used reasonably high quality unit and one low hours piece of crap, it happens. I've helped two friends fix cooling system leaks on three different cars within a week, doesn't mean there's a single external cause of all these problems. When it rains it pours.

Its not that great a diagnostic tool and most consumer stuff won't take the abuse. For example my old Sony TV's remote circuit became flaky and intermittent. I knew it was a problem inside the set because the symptoms were same despite using several different remotes. My dear wife's "solution" was to repeatedly bang the Sony OEM remote on her hand . As a result the battery door broke and the battery contacts became permanently bent out of shape.
