Question about Mitsubishi WD-52525 52" Rear Projection HDTV
I have the blue flickering screen issue... which after reading other posts... seems to be a swollen capacitor issue.
Can someone explain to me which repair kit I would need to purchase from http://servicemanuals.vstore.ca/index.php/cName/repair-kits
They list 3 kits:
V26 DLP Signal PCB Repair Kit
Mitsubishi V26 DLP power PWB Repair Kit
V26 DLP FMT PWB repair Kit
Which would I need to get?
(Also, im told that they have a service manual with the kit correct?)
2 swollen capacitors on the power supply (first board you can see on the chassis when you start to dissassemble) big caps... 3300 uf... 16v i think. these caps can also induce a 3.4 code (lamp error) and all around **** picture. fmt failures can range from black and white checkerboard pattern on the screen to wavy lines over the picture and also the blinking green light. DM failures I've seen include the blinking green light , wavy lines, and weird digital failures like horizontal bars green blocks or the picture being cut in odd places.
also when you hear that the failure is caused by the capacitors (blinking green light mainly) the culprit is not only the bulged caps. This is why you can change all the caps on the boards and still not have a working tv. its about 80 surface mount caps across both the fmt and dm. techs, look at your replacement boards and notice the darker print on the 47uf caps. good luck trying to change them it takes me about 3 hours to do both boards and about 45 dollars worh of caps.

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.
