I haven't had my tv longer than a year, however, it just shuts off by itself. What's up with this?
I have a Samsung DLP HL-S4266W that turns off by itself, sometimes when I first turn it on, and other times after 15 minutes or so. Sometimes it doesn't experience this problem. I haven't been able to detect a pattern.
I have about a 3 foot samsugn tv that our son purchased around three years ago. We got a great rate as he works there. The past week i can be watching it and it turns inself off but turns itself back on within 5 seconds. The problem now is it is doing it every 30 seconds. A real pain. We only watch the TV at night as it is in the bedroom and we have it set to go off at a certain time. I have had some surgery and have been in the bedroom with TV on a lot in the past two weeks an this at first was just coming and going. I called the number that was on our purchase agreement and it will cost 150.00 just for someone to walk into our home. The it cost 50.oo per minute to work on the set. We paid less then 300.00 for the TV. When it first comes on it is fine and within one hour it starts doing the off and on thing. I just have left it off and going to another room to watch TV. Please help as to what to do.
I had a friend with the same problem. He had to clean the components and fans in the set. The accumulated dust had caused the set to run hot and a safety switch was the tv off. He purchased a few cans of compressed air and, as he blew the components and fans out, used a vacuum to capture the blown dust. Good luck.

replace flyback transformer (same type - equivalent will not work ) - this part's work is to supply voltage to TV TUBE - after 4 years ( 4 to 10 years - depending on usage ) this part becomes weak then in top brand TVs automatically TV senses this deffect & well in advance it shuts off TV to protect other components from getting damaged due to this flyback transformer ........... as on now in your case only flyback transformer is deffective - so replace it as early as possible ....... click below link for more details on how to replace it ...... http://www.fixya.com/support/t10123898-panasonic_ct_36hl43g_tv_just_turned
If your sure the switch is broken, you can remove the switch and directly attach the wires and plug and unplug to turn it off and on. But it sound like that if the switch is broken you have a slight connection and with an ajar it will turn off and on by itself. The good thing to do would be to purchase a push button switch at your local electronics store for between $1.25 to $10.00 depending on what one you would like to have.
if it is remote control you could have what they call a sliver on the circut board to that can cause this to make the tv turn off and on. Best way to check this is to take the remote batteries out and see if the tv still turns off and on. If so replace the switch.
The main board/switch is worn to the point it will not work anymore after a while, I been in the business for years, These are wonderful TV's, yes there are replacement parts but a quick fix your looking for here will be unsuccessful this is the reason I am providing my advice and take a chance on the rating your going to give me. Try www.ebay.com look for people that is saling parts for these TV's.
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
If your TV is less then a year old, still under manufacturers warranty. I service these power supplies, for more info write to email@example.com
First of all, you should try making sure in your menu that you do NOT have your timer set to shut off. You'd be surprised how many people call Zenith every single day and fuss at me because their tv is 'broken' and they have a timer set. Secondly, it sounds to me like it could be an issue with your power supply. Does it turn itself back on randomly as well? Do you hear any popping sounds when it turns off? Check with your manufacturer to see what their repair warranty is. Some have full warranties for 90 days parts and labor, and some have it parts and labor warranties for a full year. You'd be surprised how much the customer service agents working for your tv's manufacturer actually know about the product. Give them a call for sure to get more information! :)
