Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

I have a Mitsubishi WD52631 that seems to have intermittent problems turning on

Most of the time when I turn the TV on, there will be sound, but no picture. Then after about 10 or 20 seconds it will shut off. But sometimes, the screen will turn on for a few seconds before it shuts off. And then sometimes it will start up with no problems. When it does shut down, I have checked the diagnostic code and it show 34 (Lamp failure). I did replace the lamp about 8 months ago, and since it does work sometimes, I have ruled out the lap itself. Having done some research, it seems to be the Ballast failing. Though I did have the ballast replaced years ago when it was experiencing the overheating problem that seemed to be common with this model. I have been searching for a replacement ballast but every online store with a reasonable price seems to be sold out. Does the ballast seem like a reasonable culprit? And where can I get one cheap? thanks!!

Ballasts were sometimes problems with this set, but I also ran into problems with lamp thermal sensor. It's a small rectangular device sort of cream color and about 1/8th X 3/16th X 3/4 inch in size with lead coming out of one end. Also check safety interlock switch, which is actuated by lamp access cover being properly closed.

SOURCE: Tv Shuts off occasionally 1min upon power up shows red lamp light

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

SOURCE: Mitsubishi WD-52525 Failure

Who needs a repair manual when I have you guys!! Last weekend, my 52525 died almost three years to the day. So rather than throw it away or spend hundreds (not to mention the inconvenience) of dealing with a repair shop - I read your posts. So I dismantled the unit (easily with all the great advice), found the swollen caps, ordered replacements from Mouser, installed, reassembled and the set works perfectly. Also cleaned and realigned the mirrors while it was apart. Like a new TV. Cannot thank you guys enough. Not to mention my family thinks I'm a hero!!

SOURCE: wd-52531 has sound, then clicks off after few seconds

It can be the lamp. But the color wheel and ballast can cause the same thing. Put your ear to the back of the set when you push the power button and you should can here the color wheel start up. If not, that is your problem.

Now if the lamp is not lighting up. you should here a ticking sound from the back of the set, if not the ballast is bad. If the lamp is coming on and then going out after only about 5 seconds AND you do not here the start up of the color wheel, the color wheel is confeirmed bad.

SOURCE: New bulb/TV still shuts down

Its far more likely the result of the power pwb capacitors that have failed. As the 34 code will appear if the capacitors fail on the Power PWB. You can get the V26 DLP Power repair kit at the following link.with free instructions

Mitsubishi vs-50609 wont stay powered on


Hello nicolastran,

I gave this advice to someone with this same problem so here it is again:

It sounds like your shutdown circuit is being activated. This is due to excess current being drawn. This usually happens in the High Voltage section of the TV or one of the deflection stages. Due to the nature of this problem I would suggest that you take it to a local TV repair shop or have a TV repair person come out and take a look at the issue. The HV section is dangerous and should be dealt with by a qualified TV repair technician.

Thank you,
I hope this helps

Tv turns self off when turned on


Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

Power light blinks and no picture


No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.

TV pops and shuts off


Its two maybe three issues that your having trouble with. First thing is the convergence. That problem could be a cold solder connection on the convergence IC's or the Ic's have a thermal problem, as after they heat up they go bad. The second is the popping. This could be an issue with the rear channel Audio output Ic intermittanly shorting and shutting down the set, or it could be a bad ground around the picture tubes, or a leaky hi voltage block, or a second anode lead going to the picture tubes could be split. The other common problem with this set is the STR#### regulator IC in the power supply. Now unless your a tech you shouldnt attempt any of these repairs as there is very high voltage in this set and could cause great harm to you. seek the help of an authorized repair shop for Toshiba. Try this # if you cant find one in your area 800-457-7777 Good Luck
