Question about Mitsubishi WD-52725 52". Rear Projection HDTV

1 Answer

Red light came on tv , replaced lamp and still no picture

I had the lamp go out on my tv , i replaced the lamp and i restarted the tv , it made a sound as if a fan was going , then the noise stopped , the sound was on but no picture , then 2 minutes later the tv shut off and the red light status came on in the lamp section , is there something im not doing or did i get a faulty bulb ? Is there a reset process im suppose to go through when replacing the bulb ? Any help would be appreciated , thanks WD52725, have an error code of 12, no problem found check power supply. So I checked the 5 volts at J9 pin 1 and 2, the 5 volts is there. I did find a 1000uf @ 16v cap bad on the power supply. C9a61, it was puffy at the top of the cap. I checked it and it was very leaky and had a value of 560 uf. Changed it, no difference. I figure to replace the power supply board but want to make sure that will do it. Don't want to spend much on the set where it is an older one.

What do you think?

Thanks in advance, Jerry

Good Day;

Bad news this TV has multi problems, check these:

1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). Good Luck, big IRISH.

I have a sony kdf 50e-2000 the green light goes on then it goes to thr red blinking lamp light. I have no sound or picture. If I replace the lamp light will I get sound and a picture again?


Hi,
Yes, if you have not replaced the lamp since you purchased this TV.
Lamps usually last about 6000 hours.
I've seen lamps last much longer than 6000Hrs, it all depends on the usage.
Remove the lamp from the TV and do a visual inspection, see if there's a crack on the glass or the bulb.
If the TV is few years old then the Lamp may be bad.

For a new Lamp: 800 638-3328

DO NOT BUY the lamp from ebay

Good luck to you.

hello When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for
the picture to appear on-screen. See "IMPORTANT NOTICE ABOUT HOT LAMP R
When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for the picture to appear on-screen
in the following situations:
• When the Quick Restart™ feature is set to OFF and you turn the TV off and then on again within a few minutes.
• If the TV is on when a short-term power failure, power surge, or other similar power failure occurs, such that the TV loses and regains
power within a few minutes.
This is a property of DLP TV lamp technology and is NOT a sign of malfunction.
If this occurs, the green LED on the TV front panel will blink (and the red LED will be lit solid) until the TV is finished restarting the lamp
and the normal picture appears. If BOTH green and red LEDs are blinking at a one-second rate, you will need to turn the TV off and then
on again to restart the lamp.
ESTART" on page 8. if this no good check the lamp in side to see if it's not burn't out good luck

No picture on my 62" DLP Mitsubishi


I am not sure what the problem is, but usually if a lamp is bad, the other 2 lamps will still function. Since you are getting no picture at all, I am thinking it is a circuit board problem. TV electronics are expected to last 3-5 years. After that, many components will start to go out one by one. If you have your tv repaired, I would replace the whole circuit boards instead of just the bad component. The power board is the #1 board I would replace 1st. This is the most stressed board and will cause most of your tv problems.
