Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

"PA" plug Having the same problem as napatoy (I recently changed about 10 capacitors, but I'm having problems with plugging in the correct wires. I labeled everything, but I can't seem to find a wire for "PA". Can you tell me if this should be left without anything plugged into it or should I keep searching? Thanks for your help.). I even photographed the boards prior to disassembly, but still can't solve this one. Is the PA left blank?

The PA needs to be plugged back in or the set will not work there is a jack there. make sure it did not get pushed somewhere out of the way or under something.

I have a 67 DLP samsung TV that recently started turning it self off after just a few minutes of being on. When it turns off about ten seconds go by then you hear a click and the two green LEDs on the...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

T.V. Clicking for 10 minutes before it turns on


Scart leads or scart adapter would never cause such problems. The problem will be in the TV itself. You need to check the power-supply unit at the main-boar. First look for visible cracks at the other side of the board, then you might need to check all the low voltage capacitors at the power unit. In most cases 100 Normal 0 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:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} µFx16V located just next to IC causes such a problem. Only one TV out of 430 had actually defective IC itself, and TV was stil working after 6.26mins. So in your case I'd check low voltage part of the power unit.

Devices do not display visual or audio input, just a blue screen.


You need a repairman. These sets have a bunch of small capacitors that fail on these sets. There is more than one board with this problem. Do your homework and find a good reputable repair shop to fix this for you. It's not something the average person can do. Sorry for the news. Not a simple fix. Mistubishi has a problem with capacitors and it's been this way for more than 20 years. It's ALWAYS bad capacitors that cause Mitsubishi's to fail.

Mitsubishi tv model VS6061 rear projection with rolling picture.


I know this is an old thread, but I would like to post this information in the hope that someone will find it useful.
I just finished fixing this problem on my 1994 VS-6061... the problem is the PIP (Picture In Picture) board located on the Power Signal board. The PIP board contains the numbers 530B552. I bypassed the PIP board by following the directions I found at the following link:
http://forum.doityourself.com/entertainment-center-tvs-stereos-vcrs-dvds/130383-mitsubishi-cs-35301-rolling-picture-problem.html
"Plug in a 4.7ufd @ 35v filter cap (+)at pin 5,(-)at pin 11. Plug in a .01ufd(any voltage) between pin 7 and 9. Just plug the caps into the socket, where the PIP board was mounted (they don't need to be soldered). Just don't let the leads from the two capacitors touch, as they cross each other. The 0.01 cap is non-polarity, so either way it plugged is fine. Basically you will bypass y-signal through 4.7u, in pin 5, out pin 11, and bypass c-signal in pin 7, out pin 9 of the PIP socket.”

The bypass requires 2 capacitors: One 4.7ufd @ 35v and one Non-Polar 0.01ufd @ any voltage.
Remove the PIP board, then plug the two capacitors into the socket where the PIP board was mounted: plug the 4.7ufd capacitor with (+)at pin 5,(-)at pin 11 and plug in the non-polar .01ufd capacitor between pins 7 and pin 9.
If there is a ground wire (possibly brown) soldered to one of the tin cases on the PIP board, then you should connect this ground wire to the PIP socket either at pin 2, 4, 6, 8 or 10 which are grounds of the socket.
This PIP board was used in many Mitsubishi televisions and they were plagued with problems...This is why many of these older Mitsubishi televisions had similar problems…
Good luck

Panasonic shows multiple board replacement in sequence of boards that may be the problem. they start with the PA board as the most likely culprit start with that. how ever there may be 6 other boards that can cause a 10 flash code.
the PA board part # is TXNPA1BJTUJ.

TV will not turn off


Wow.. How is the TV plugged in? I had someone with a Samsung DLP do this but hers was plugged into the cable box that was plugged into the surround sound receiver which was plugged into a back up which was finally plugged into the wall. Feedback caused an electrical feedback causing really really odd tendencies.

Second, that connetion between panel and set has a row if pins make sure the second one is not bent because it could be on permanently or causing it to have a constant connection . It is so hard to explain this hope this helps.

Flickering blue picture


I finally got around to dismantling the TV. This is no mean task. The chassis is tethered to the rest of the set my over a dozen wiring harnesses and a few of these cannot be disconnected near the chassis but instead require removing the “right support” near the air duct and taking the shield off the lamp ballast. Once the chassis assembly is out, it is a further significant task to disassemble it to get at the various PWBs (POWER, FMT and DM) having the suspect caps. I’m sure reassembling everything will be a fun job!

I have not yet had a chance to fix and reassemble but I wanted to post this no as I’m not sure when I will get around to it.

I did find six of the fourteen known-problem caps to be visibly bulging -- both 3300s and two of the four 1000s on the PWR PWB plus two of the four 1000s on the FMT PWB (see photos below). Ironically of the four 1000s on the DM PWB, which I have heard are the most common to go bad, were bulging and I considered skipping these as the DM it is the toughest board to extricate from the chassis, however I figured I had come this far and I would just as soon replace all twelve 1000 uFs as the parts cost $0.23 and I really never want to have to do this again.

If I had to bet, the two 10V 3300uF caps on POWER board, which were actually leaking black goo, are the actual culprits, but with four of the 1000 uFs also bulging it is probable only a matter of time until they failed as well.

Here is the POWER PWB with the known-problem caps (C9A37, C9A38, C9A51, C9A52, C9A61 and C9A62) highlighted:

here's the FMT PWB with the known-problem caps (C8F19, C8F21, C8F22 and C8F27) highlighted:

and the DM PWB with the known-problem caps (C81A2, C81A3, C81B3 and C81B4) highlighted:
