I am in a dilemma.

My Sony TV (just a tube tv) that I bought in 1996 started blinking a few weeks ago. Initially, it was just when we turned it on after it was off all night but now it blinks intermittently all the time and is very obnoxious. We have a dvr and thought at first that it was a problem w/ that. But when we unplug the dvr, the tv still blinks. Also, it blinks somewhat on all settings (for dvd or vhs) but most often when the dvr is on. So it blinks occasionally when we're watching a dvd or a vhs tape but ALOT when we're watching tv.

We are considering getting a new tv but don't want to unless we know for sure that the problem doesnt have anything to do w/ our cable /dvr connection. True, the tv still blinks when they're disconnected from it but it also doesnt make sense to us why some shows blink more often than others if it DOESNT have anything to do w/ the dvr.

whew!

I have two TVs of that vintage that I'm trying to keep running as long as possible as new TVs get cheaper. Probably a component on one of the circuit boards is failing intermittently and causing the picture to drop out. Eventually it will fail the rest of the way and you'll have no picture. Usual solution for that kind of problem these days is to replace the whole board. A minimum cost to fix will probably be $100. You'd almost certainly be better off replacing the TV than spending over $100 on a 12 year old TV.

Yeah, that's what I thought. I guess I'm just afraid of getting a new tv and still having the problem! Directv has already told me that they won't replace my purchased dvr...they'll have to 'lease' me one for a fee each month. sTupid.

I think your television just needs a day out in the country.
Seatbelt your tv in the seat and go for a drive on some nice windy roads. And if you have a nice dirt road with washboards nearby so much the better. Tvs like bumpy roads.

Or you could open up your television and turn every pot (potentiometer) in there. And anything else that can build up corrosion between contacts. But its more fun to take it for a drive.

If that doesn't work, do what Bowie says.

Cheers,
Aeroman

Odds are your high voltage rectifier or powersupply is failing. Plan on buying a new TV, up here its, !%) for them just to look at it and most will tell you its not worth the expense. Digital TV is only a year away, and yes you might not need it but the timing is right.

Default freakin tv

my sony has been having the same problem. I got it from my friends dad, thats why they got a new one. But it used to just blink a few times when you first turned it on, but since i got it it has been getting progressively worse. Now it wont ever stop blinking, if it does it will start up again if i click something on my xbox, or tv controller or any other action on the tv. help plz??? any home remedies?

The Digital TV Transition: FAQs - Consumer Corner - Digital Transition

Check out the date for digital conversion when analog signals will end unless you have a converter box. Could this be the problem?

Ever heard the expression "on the blink?"

There is likely an issue in the high voltage section. Could be dust or something causing an intermittent short, or failing insulation, or a number of other possibilities. Your best bet is to just replace it. Put a wanted ad on craigslist and be prepared to be inundated with people wanting to dump their non-digital sets.

Now, about home remedies - unless you are an electrical engineer there are none. The high voltage section of a tv with a cathode ray tube is about the most dangerous place to play in your entire life. There are capacitors that can hold charges for long periods, and when the system is energized, think of it as one of those zapping bug lights designed to kill humans. IF you don't get yourself killed witht he high voltage or capacitor discharge, you still have a chance of breaking the thin neck of the tube and causing an implosion that will embed shards of leaded glass in your body and eyes. I know what I'm doing and have replaced video driver boards and all that good stuff, and the back of a CRT still scares the heck out of me.

I had the exact same problem with my Sony XBR. The picture tube
and the voltage coil at the back had both simply wore out. Neither
could be replaced since Sony stopped making parts for Analog TV's.

So , as luck would have it, I happened to find another Analog Sony
on a closeout to replace the XBR with.
