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.

I have a Samsung 50" HDTV DLP TV that I purchased 10/12/2008. I turned the set on the other day and it would come on generate a normal picture then power itself off. I unplugged the set for a few hours...


Try cleaning the dust out of the ventilation slots. Check your owner's manual to see if there is an air filter that needs to be cleaned out periodically. If the set is overheating, it will shut down.

If you still have problems you may have a dying power supply capacitor. There are several off-brand companies making cheap but unreliable components; a number of manufacturers have had problems with these suppliers in the last several years.

Another possibility is a tin whisker short. Tin whiskers are a drawback of lead-free solder. These microscopic slivers of metal grow out of solder and can get long enough to short-circuit to something else. This would be tough to find, especially since it apparently has to expand with heat to touch whatever it is messing up.

Mitsu 57731 problems have wide bar across screen


This is an ongoing problem with Mitsubishi DLP HDTV's contact the Customer Service at 1-800-332-211. Tell them this has been going on for a while and you want the TV either Fixed or Replaced. Ask for Adrianne Hardt, she is a Customer Service Manager...... TELL HER RICK GRIFFITH told you to call.

I am in the 4th week negociations with Mitsubishi over these exact problems. I purchased my 57" DLP HDTV in Aug of 06. Replaced the Lamp 3 times and have had 5 Service calls. I DO NOT have and extended Warranty. Mitsubishi provided me with the extention in writing and stated if any problem occurred again they would replace the Unit or provided monetary compensation.

Good Luck and be persistant.

Any of you can email me for from info and covette54@live.com

I have a sharp tv model #LC-46SB54U and a small Analog box keep appearing in the right upper corner while watching tv. How do I stop that box from appearing?


Good Day, 49erfan;
As a Texan's and Lion's FAN I'm not sure if I should give you any advice. First of all GO 9er's!!!! I love you too. Try this since I don't know what "box" you may have. See if "box" remote has a "display" button on it. If so, press. Also, try resetting BOX by unplugging for 2 to 5 minutes. IF NO FIX call service provider, TV is not the problem. Good Luck, big IRISH.

Dark shadows similar to fingers of thunderstorm cloud have appeared on the display and worsened over time. They are fixed in position. Is there a fix? Is it time to replace our 2 1/2 year old Protron?


Not fixed but bearable by increasing brightness. I'll live with it until it gets worse then, probably, replace the unit. One other symptom for anyone interested is a dip in the top edge of the display just above the area of thunder cloud finger.

Toshiba 42H81 Blinking on and off light


Very common problems with this TV set. Toshiba even has a technical bulliten on this and several other models of tV set. The negitve terminal of C809 and C810 need to be soldered, as there are no eyeletes in the printed circuit board. This problem could also take out the fuse, F860. Replace if necassary. Good Luck
