Question about Mitsubishi WS-55805 55" Rear Projection Television

1 Answer

Just plain dead

I've used the tv for years with no problem. Now it just will not turn on. The electric outlet has power, but the tv does nothing. No picture, no sound, no lights, not even a click or a blink when I try to turn it on, whether by the power button on the tv or on the remote. Thanks for any advice.

Our electricity went out for a few minutes, and since then the TV will not turn on. The green light is flashing. We tried resetting it by pushing a pen point into the reset hole, but it does nothing. ...

Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Thanks for using FixYa. You’ll need to reset the Projection TV and to reset it follow these steps:

  1. Turn off the television and wait for 5 minutes.

2. After 5 minutes unplug the television power cord from the electrical outlet.

3. Let the television remain without power for more then 1 minute.

4. Plug the power cord back into the electrical outlet. If the television is plugged into a power surge protector, remove it from there and plug it directly into the wall outlet. Turn on the television. If the issue is resolved, then the problem is with the power surge protector and not the television.

If the issue is not resolved then this might have happened due to over-voltage. Please check the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Mitsubishi rear projection TV , Model VS-45603.In the last year it started to turn off by itself. It has no real pattern. It can turn off 2-3 times one day and none the next day. It is hooked up with...

What kind of cable are you using to connect it with (coax, HDMI, RCA (composite), component, s-video)?
This may be a grounding problem. Either the cable from the satellite dish is grounded to something with a little electricity running through it or you may have a hot ground in your electrical outlet. Or the cable may be on a different ground than your electrical outlet and by connecting the two it has created a slight electrical current. You can try using a plug adaptor to remove your receiver from the electrical outlet ground. These adaptors are meant for older homes and electrical outlets that do not have a third hole or ground plug. The outer metal part of all video connectors is the ground and this may be causing the tv to act strangely.

I hope this works.

RCA D52W23 has shut off twice within the last week..

Try a power drain and monitor if the TV continues to do this or not:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If this doesn't resolve the issue, it's possible the power supply is on it's last legs.

Emerson LCD 32" TV....Model # LC320EM82....Power problem, powers up and powers right back off almost instantly....i have tried to google a solution and so many people are having the same solution but...

Okay!First i need to isolate your electrical outlet is working. Use another Video/Audio component(ex. dvd player) and plug the power cord into the TV outlet,be sure it has nothing to do with the outlet.
If the outlet is working properly,Unplug the TV power cord and wait for 1 minute before you plug it back in the outlet.Turn on the TV MANUALLY without the remote control and see if the power stays on,if not,sorry,you need it to be repair.Don't waste more time on it. If you only purchase it for few months with a reputation retailer,there is no reason NOT to call them up,cause it should be still under warranty?

General electric older tevelision stopped working

"Stopped working" is a little vague. Are there any flashing LED's? Any start up noises? If the TV seems dead in the water, try a power drain:

1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board.
3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on. If this doesn't work and the TV appears to be dead, it may only be the power supply that is now defective and service would be required.

TV won't turn on

When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.

TV won't turn on

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

No power to tv

You say didn't do anything, Like did you hear a squealing sound or did you see led lights on front of panel or just dead nothing? If dead and nothing then look for fuse blown in power supply if not then there maybe a small sound coming out of set when you press power if so then the power supply is trying to start up then you will have to look elsewhere like horizontal or convergence or vertical areas.
