Do you have it on a power strip?

Posted on Dec 22, 2008

  • karen davis Dec 22, 2008

    try a different plug altogether, sometime the power strip can not handle power a lot of items. When you buy another power strip make sure it can handle all the items. We hand the same problem of the tv turning off after a few minutes because there was too much items on the power strip. if that does not help than its with your TV.

Sony sxrd picture sound on off


In this case, it will be best to contact any service technician. These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Tv is on, after a few minutes it goes black and there is no sound. The indicator lamp is still green and stays solid the entire time. Without turning the TV off, in about a minute, you hear a small buzzing...


Someone else gave me the tip as I had the EXACT problem, but no buzzing. Unscrew the panel on the front bottom of the tv. Once that is off, there is another screw that opens a little panel. Unscrew the single screw with an allen wrench and pop out the bulb and casing. Mine was full of dust etc. Used an LCD cloth, but compressed air would do the same thing, put it back together and it works great!

KDF E60A20 screen goes blank loses sound for 10 60 seconds


I've had this same problem ongoing for a couple weeks. Finally, tonight it would shut off every 20-30 seconds, stay off for another 20-30 seconds then come back on. It turned out to be my bulb. I blew the TV out with compressed air, removed the bulb and disassembled it. Taking the bulb out of the plastic cage I then remove one of the metal screens at the top of the bulb, it just has little clips holding it in. I took a bottle of rubbing alcohol, some Q-tips and proceeded to clean the inside of the bulb through the screen hole. After cleaning the inside I put the screen back in, cleaned the outside of the bulb with a rag and alcohol, then reassembled everything. The TV is much brighter, I had to turn down the brightness setting and has been running the last few hours without an issue. You can avoid all this by buying a new bulb but I don't have the money right now to replace it and I'm cheap so I'll milk this bulb for everything it has. Heat kills bulbs so if you clean the screens and blow out the TV once every couple months you'll get a lot of life out of it..... I'm almost to 4 years on my original bulb and my TV is on constantly!! Good luck to all!!

Samsung tv turning off by itself


I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
