Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

Every several hours the screen goes all blue, and the set turns off.

When the screen goes blue, none of the controls work. After a minute the set turns off with rapidly blinking green light. When turned back on everything works properly for another hour or more. This happens 1 or 2 times every evening. All connections have been checked. The set has been reset..no help

    The fans are working, they have been vacuumed and cleaned...no change, I get about 2-3 hours use before it shuts down. Have ordered new bulb as I have had set for 2 and 1/2 years...but signal is solid green. Lamp likely overdue. Is it likely this is an external problem? Thanks

Mitsubibishi wd series 73"..Mitsubishi ws series 73" dlp. Works fine but after several hours of viewing screen scrambles then goes blue and sound goes off. I can switch to another input and watch ama


A couple of suggestions, if only on cable and using a box disconnect the set and box from power and after several minutes repower and see if a reboot helps.

The two models listed here both should also have a soft reset done with the original remote and the set on---Menu,1,2,3, enter.

I turn on my sony TV and it goes straight to blues screen. model number is kp-51hw40


These sets have a history of bad picture tubes, the blue is most common, there is a way to without replacement of any parts to attempt to correct this.

you have to remove the entire grill on the front below the screen; it is usually held in either by two screws at the front (under little plastic caps) and or screws on the back on either side.

The grill will pull out and is engaged with large plastic tabs at the top; with it out since the front keyboard is mounted into it you lift and tilt it to the left. Remove the inspection plate behind it: look for the screen/focus block (see attached photo) and note the six controls: three are screen and three are focus----do not touch the focus ones.

They are usually marked (may be hard to see: r,g,blue) You want to locate the BLUE SCREEN CONTROL and with the set on on a unused video input turn the screen control SLOWLY (usually to the left) until you see no blue in the background; if you do it correctly all you should see is the Video 1 etc.


The idea here is to lower the blue screen setting just slightly-if it works you may only be buying some time as these sets are prone to problems like this.

I have done this several times and many see a few more years of use before they have to be replaced.

Let me know before you attempt this if any questions.

My sony kp-57ws500 turns on and works fine for about 15 min but then fades to blue then goes all blue. i took the back off and when it starts to fade to blue the green tube and red tube fade off. what...


These sets had problems with bad picture tubes that cause this exact problem, but there is something you can try that may help you get some more use out of the set.

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the GREEN will be in the middle.

7.) Once you locate the BLUE control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Screen control.

8.) Best way to do this if the set is on is on a video input clip_image001.gif with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----turn it down slowly until the blue screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the screen down a few times to get it to stay on.

If this works you may only be buying some time and if it is the tube sooner or later it may return with the same problem.

After the tv is turned on it turns off 3 or 4 times after turning it back on and the screen turns blue for a few minutes before becoming clear. It lasts longer each day.


Many of these sets had problems with bad picture Tubes--they use a red, green and blue crt. Most commonly the blue gives troubles--The tubes are now only available on a rebuild basis--usually not worth doing as the cost is very high.

You may have a bad blue picture tube but there is a way to deal with this first----the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue)

Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control (they are black like the block) With the set on(be careful) go to a video input clip_image001.gif with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 -500 parts and labor.

Screen flashes blue, then shuts off. red light blinks eight times, then repeats


This model had a lot of problems with bad picture tubes--the blue one is the most common to go bad--the tube will pull so much current the set will go into shutdown.

The tubes are only available on a rebuild basis--very expensive and usually not worth doing.

THERE IS ONE OTHER THING YOU CAN TRY TO DO TO MAKE THE SET WORK FOR A WHILE.

Tv just turns off while watching it the screen goes blue than turns off


This is one of a group of sets (KP-57ws500) that had bad picture tubes---all of them had this trouble.

The picture tubes are no longer available from Sony--only available on a rebuild basis from another company--very expensive and usually not worth doing---blue is most common tube to show trouble.

The set is shutting down because if the screen goes bright blue---it pulls too much current and the set goes into protective shutdown.

There is one fairly easy thing that you may be able to do-----I have done it before.

What it entails is getting at the Screen/ Focus control block and turning the Blue Screen control down--if it works it may just buy you some time but I have seen several sets where it allowed the set to have some more life.

Usually if the set was working the way this problem begins is you on a blank video input notice a slight blue color in the background with some faint curved lines visable.

If you want to attempt to do the adjustment--let me know and I will tell you how.

I am here to help people----I have seen over 100 of these Sony sets with this problem---replaced tubes in many of them when they were new or under warranty.

Screen turns blue


You may have a bad blue picture tube but there is a way to deal with this first---This is a 2001 model and does not have a light engine---I did one of these with the same problem a week ago---the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue) Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control(they are black like the block) With the set on(be careful) go to a video input with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 - 500 parts and labor.

this set has 3 temperture sensors.If the set gets too hot it will shut down.
first clean the cooling fan as it may be full of dust.
if this is not the cure the one of the sensors is likely bad.

Have you tried magic focus? if that doesn't work
replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years
