Lamp light on tv front will lit if lamp is dead/ broken.

It is possible you have a power distribution problem. A $100.00 fix at a trusted TV repair shop.

the problem with this tv is the contlor box , there about 12 capacitor that need to be replace , but some times the eepron is bad , normal repair on this unit is $450

You probably have some capacitors going bad in the power supply. This particular model is a bear to work on,...really hate them. The entire electronics section has to be removed, a large shield removed, a lot of plugs undone, the board unscrewed and removed, and then you can change the bad caps. I don't recommend trying it. And worse...after replacing them something that has been stressed because of the bad caps tends to fail and you still have problems, like the green light on front never quits blinking after you plug the set back into the wall outlet.

With the Mitsubishi remote : Menu, 1,2,3 enter

There is also a hard reset by the one above (soft reset) should be tried first----

Let me also know the reason you are trying to "reset".

the FMT caps have most likely failed. You can get the V26 FMT repair kit from www.tvrepairworld.com which also contains instructions.

What is your input source and which input cable type? If the source is a PC using a VGA cable, what resolution is the computer sending? 480x640. 800x600, 1024x768, 720x1280 (EIA standard) all at 60Hz are known to work but other modes might not.

If you are using a PC to the HDMI port, it will not work. The only HDMI ports that can connect to a computer will be listed as HDMI/DVI and this TV doesn't have that type of HDMI port.

If you are using any other input source, check try another source or channel. (One of my TVs intermittently finds a digital channel 25-9 and gives that message. We have no clue what station is being found but all the other channels are fine.)

I hope this helps.

The caps on the DM and power boards need replacement. Yo can get the repair kit called the V26 Chassis DM/Power repair kit from www.tvrepairworld.com which has the caps and the CD with instructions.

Tv CRT tubes require coolant replacement.Tries websites like Tvrepairworld.com,Tvrepairkits,.com to buy the coolant kit to replaced it coolant on the CRT pictture tubes.

What color is the status light blinking as that is a error code depending on which color it is.

bad filtor capacitors. common prob with mit. J.D.W.

Unfortunately the first generation DLP's from Mitsubishi are prone to have Capacitor failure through out the chassis. Most likely that is what your set is experiencing. I would start by replaceing the suspect caps on the DM amd The Power boards. You can get the V26 Chassis DM/Power repair kit from www.tvrepairworld.com which also contains instructions.

My Mitsubishi WD52725 will not turn on...the timer light is blinking. We pushed the reset button, unplugged tv. Just got off the phone with Mitsubishi customer "service." After answering numerous personal questions, and being on hold for several minutes, I was told that the only solution was to push the reset button. Duh! We'd done that several times with no change, which is why I called them! BIG WASTE OF TIME!!!!

Does it shut off on a spcific channel?? if so its your signal board
Jim

does it give you the "airflow" message?
if so it needs a new thermal sensor by the lamp, known issue defective sensor..

if not, suspect bad capacitors
there are many bad caps across 3 board , all part of the chassis.
a repair center will ship the chassis into mits for rebuild, about 400 or 500 total bill

This is a common problem and usually shows up when power is interrupted. The capacitors in the micro, digital, and power supply have to be replaced. In my shop, we prefer to send the chassis to Mitsubishi and they repair it. Do you have a local authorized Mitsubishi service center near you?

http://www.tvrepairkits.com/xcart/home.php is your answer. I just did mine and it worked like a charm. For 46 bucks, you can't beat it.

Yes you can.
Speakers are probably good unless they were subjected to the elements(outside TV's do get damaged sometimes from being outside on patio ,etc.
