My tv set just went out. it just turned off - the red light (LED to determine the power-on status of the television no longer appears). i tried changing the fuse on the plug and tried different sockets etc. but no luck. Seems like something's wrong on the inside. Any suggestions would be appreciated.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

Hi there,

This model as 3 LED indicator lights:

1) Power/Timer 2) Status 3) Lamp


If "STATUS" LED is blinking RED:

1) Internal Fan has stopped. These tv's require fans, to prevent overheating and causing damage.

If "STATUS" LED is solid RED:


1) Circuit failure (short)
2) Disconnected DVI cable, chassis to engine
3) No LAMP-EN signal from Engine to turn the lamp On.
4) Ballast UART communication problem.

If "LAMP" LED is solid RED:

1) Lamp Failure - Lamp failed to turn On.
2) Lamp is broken (e.g. burst or blown)
3) Lamp turns Off during P-ON

There is no data relating to TIMER LED being solid RED.

Hope this helps.

Cheers,

Scott

Manufactureres usually keep their schematics to themselves however you may be able to contact them to purchase a new power supply.

Please intimate exact model of your Sony TV to find out reason of no power up.

same problem, red blinking light in series of 5 flashes

Check your lamp; it may have blown. Sound, no picture and a red light are classis signs a lamp has failed.

I DO HAVE THE SAME PROBLEM , ONLY THE RED LIGHT BLINKING ,NO SOUND NO PICTURE '
PLEASE I DO NEED HELP TO FIX IT .THNKS

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!

if the "status" light is blinking red than you most likely have a fan failure going on inside the set. there are 5 fans in the tv and it could be any one of them.

First before a reset the set must turn on, if the set just sits there with the red LED on you have further problems, so does the set display anything?
