Question about Mitsubishi WD-52525 52" Rear Projection HDTV

2 Answers

Where do I get a PWB-signal 930B923002?

I previously posted the blue screen with sunburst pattern problem. I replaced the lamp and still have no signal - just a blue screen that is flickering and flashing. After reading simular posted issues(blue screen with no signal), many suggestions were to replace the PCB Signal 930B923002. I suspect this is what is wrong with my unit, but where do I get this part? Mitsubishi's website only shows how to order lamps and remote controls.

    i HAVE A SIMILAR PROBLEM WITH MY WD-62525, IT HAD A BLUE SCREEN WITH STATIC IN THE MIDDLE, IT SAID COMPONENT CABLES WERE IN VALID, I SWITCHED THEM AROUND WITHOUT ANY FAVORABLE RESULTS, THEN I WENT AND REPLACED THE LAMP TWICE, THE FIRST TIME I GOT RED LAMP SIGNALLING A LAMP FAILURE, THAT WAS THE REASON FOR REPLACING LAMP AGAIN, STILL AFTER A COUPLE OF MINUTES I GET RED LAMP AGAIN, IS THERE A PROCEDURE TO RESET LAMP TIMER ???, I TRIED SYSTEM RESET TO NO AVAIL. THEN I HAVE TO TRY TO FIGURE OUT THE OTHER PROBLEM ONCE I GET MY BLUE SCREEN BACK.

You need to find a local servicer to order parts for you.  It seems like a gamble to replace the signal board without further troubleshooting.  Minimally, you should check your power board for swollen capacitors, as this has been a common problem.

No picture or sound mitsubishi 62525


Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.

Blue Flickering Screen - Which Repair Kit?


yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.

Unable to receive input device signal


Can you post a picture of the screen so I can properly diagnose it. It sounds like the caps on the FMT PWB but a picture would help me be certain.
