SOURCE: Red light on no picture will work fine after several minutes

There is a list of things you need to check, but offhand I'd say that the 5 volt line is low and probably right on the"edge", which is why it works sometimes and not others take a look at this list:
Cause #1
1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for
12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check
for an open F9A09 on the Power PCB, if it is open replace F9A09 part #
283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out)
Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if
low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the
Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three
times and then the unit shuts down with a red lamp LED (lamp error). Replace the
Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch
to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low)
after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB
(ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-
volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010

I would say try #3 first, the two caps on the pwer supply board. A couple of warnings: as always, unplug the unit before servicing. The power supply is located on the left side, if you behind the unit. It is in a shielded box and the shield has VERY SHARP EDGES so use care when you try to open it or you will slice your fingers.
Please be sure to rate this solution. Thanks!

SOURCE: Mitsubishi WD-52525, replaced bulb but still not working

SYMPTOM: Power LED does not stop blinking after plug in.
CURE: Check C81A2, C81A3, C81B3 and C81B4 (1000 uFD, 16V, 105C) on the DM PCB.
Check C8F19, C8F21, C8F22 and C8F27 (1000 uFD, 16V, 105C) on the FMT PCB.
If any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).
this is what we at the shop check first. it is quite common. on the power supply board look for swelled up capacitors

Press the input/device button and the menu button at the same time. Green LED will blink a two digit code blink 1st digit short pause blink 2nd digit longer pause and repeat. Any number of problems can cause this same symptom.

If the red LED your refering to is the Status LED and not the Lamp LED then you have big problems. A red Status LED indicates no communication from the Format board to the DMD board (light engine). 1/2 the time caps on the format board itself the other 1/2 must send entire electronics package to Mitsubishi.

Most likely the lamp is burnt out (indicator goes to constant red status). Replace lamp (get lamp P/N from User Manual for replacement), clean any dirt around lamp, fan, and rear filter. Do NOT get any fingerprints on new lamp.

Infocus X1a no picture, solid green LED


if the lamp is new, it could be the power supply (the ballast is built in to the ps). but make sure you have the right lamp. the X1 and X1a have an sp-lamp-019 and the similar X2 and X3 have an sp-lamp-018. the lamps are almost identical except for the wire configuration on the lamp plug. make sure the wires in the plug match the positions in the socket. also, when you turn it on, if you don't hear a high pitch squeal, the colorwheel is not working. and if that isn't working, the lamp won't either. also check to see if the lamp door is closing properly and hitting the switch at the top of the opening.

Flashing Green Power on light not picture


Last Saturday evening, I experienced the exact same behavior on my Panasonic PT-52LCX65; it shut itself off without warning. I turned it back on, and it shut itself back off after about a minute, and the red "Lamp" LED on the TV began blinking.

I never got any warning message that the lamp was about to go out, but I've just replaced the lamp and now the TV is working just fine. We had to mail-order the new lamp, because neither H. H. Gregg (where I bought the TV on "Black Friday" 3 years ago), Fry's Electronics, nor Best Buy carries the part locally.

My wife found the new bulb WITH its holding apparatus for something like $120 online, roughly half what other sites were charging. We paid roughly $55 for UPS Next Day Air. The first bulb that was sent arrived broken (some UPS rep apparently thought "Fragile" meant "Shake and Drop"), but the company we ordered from cheerfully rushed us another one, and the second one was in much better shape. (Panasonic doesn't pack these replacement bulbs very well; there's a heavy bulb with a lot of air around it that Panasonic doesn't fill.)

More details available if anyone wants 'em. Hope this helps. -- ChuckE
