SOURCE: My plasma TV turns itself off and there's nothing I can do to get it come back on...

This is going to sound stupid, but I have a 42" Philips plasma that'd been having the same problem lately. Eventually, I checked the power cord--have you ever noticed that the cord just hangs straight down from the bottom of the set? My guess is that over time, it slowly gets loosened by gravity, just a bit, so you get a fluttery power connection. Anyway, it didn't feel loose, but I pushed the power cord in as hard as I could, and I haven't had a problem since.

SOURCE: Hitachi 32LD8700 - TV won't turn on although has power

The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.
Hope Ya Fix It

SOURCE: Philips 42 inch HDTV - "FlatTV" Plasma -- does not turn on.

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

SOURCE: Tv went off and won' come back on.

Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts

My mitsubishi tv W55613 won't turn on. green light keeps blinking even after resetting


Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.

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.

Sanyo dp37819 i turn it on green light comes on but no picture or sound and green light goes on and off


You can send your main board to us and we can give it a try.

If it the front LED turns on for a while, then off for 1-2 seconds and then back on...we'll probably be able to help.

See http://www.coppelltvrepair.com for details and shipping instructions.

TV displays green blinking light but won't power up


This is sometimes called the "blinking green light of death" and usually means the DM unit in the set needs repair.

The only other simple thing may be the reset switch on the front of the set has gone bad; The only way to see is to get at and unplug the front keyboard on the set.

I can tell you how to do that if you want to know.

Takes about 5 minutes and if set still does not come on then the DM unit is bad.

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.

When I turn my Sanyo DP37647 TV on the green light comes on but there is no picture or sound.


When there is neither picture nor sound you're likely in need of a service or replacement of the main board.

Service is usually the way to go as replacement is unable to find or too darn expensive, at least in the past year or so.

The typical indication of this problm is that the front light doesn't just stay green, but actually blinks for a second every 15-20 seconds.

If it does that you're definitely in for service.

The DP37647 model isn't listed there as we're planning to post about it in a separate article...however it has the same symptoms as some of the others.

If you want to send the board in for repair , shipping instructions can be found at http://www.coppelltvrepair.com .

It really isn't a simple DIY service like a fuse or capacitor replacement.
