TP50H60 won't stay on

Anyone else have a problem with the power light blinking, but the TV won't 'turn on'?? I've tried unplugging it and plugging it back in, but it will only stay on for a few minutes. Any suggestions?

Count the blinks and refer to the owners manual. The blinks should tell you something about the error.

Timer light blinking and tv won't turn on


Not much info to go off of, and the video is a bit blurry. Try unplugging the tv for a minute or two, make sure to leave it unplugged to allow power to dissipate. Then try again. Otherwise I would suspect power supply problem.

What's your problem? won't turn on..... yellow/orange light continually flashes three times...


Toshiba Regza 37in - 37HL17
TV will not turn on - Yellow power ind. Light blinks three times...
Fixed with a firmware update (hard to believe, but true). Search Google for a file named: 2007SEN069.zip (don't worry if the page you find it on doesn't mention the 37HL17 - it worked fine). Unzip the file, and copy the 3 folders and 3 files to the root of a small SD card. The SD card MUST be 2GB or less in size (I used a 1GB card), and it MUST be formatted with FAT-16 (not FAT-32). Mine was pre-formatted as FAT (FAT-16). The SD port is on the back of the TV behind a cover plate near the power cable. You do NOT need to remove the back cover of the TV, just the small cover plate (1 screw). UNPLUG the TV; remove the cover plate; insert the SD card (prepped as explained above); Plug in the TV; Watch the yellow lights blink, then turn blue, then go dark; UNPLUG the TV; remove the SD Card and replace the cover; Plug in the TV; Yellow lights will blink a few times (this is normal); when blinking stops, turn on the TV and you should be good to go. :-)
Pictures attached are from a Toshiba software upgrade bulletin I found online.

My Samsung LN32C450 won't turn on and the capacitors are fine. What's wrong?


You were on the right track, it sounds like the power supply board is gone. It's more likely one of the power chips that went. (The capacitors are usually not old enough to have gone bad yet.)
(part of it still works is why you get the blue LED when you plug it in.)

If you decide to try to fix it yourself, BE CAREFUL! The power supply board has capacitors that can hold high voltages for many hours after the TV's been unplugged.The equivalent of sticking your finger in a light socket.

You'll need the part number off the power supply to get a replacement.

Sony blinking codes


If i remember correctly ten blinks means a high voltage error.
The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for you.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...


This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex


When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

Hi,
If the led light flashes green continuously, the fault came from the DM power supply. The faulty parts there are the electrolytic capacitors. Let me know if your handy with electronics and I will assist you to fix it yourself.
