Its most likely the ballast which is causing the issue. The ballast is what provides the power source to light the lamp. You can get the ballast at www.tvrepairworld.com and they can provide instructions on how to replace the ballast

SOURCE: WD-52525 Lamp failed 2x in 4 months..is it the Lamp?

Having the same problem with the dim picture on my WD-52525. Had the lamp replaced and still had a dim picture. My authorized dealer has been in contact with Mitsubishi Tech Support and they are thinking it's the optical engine (light engine).

If you think the replacement lamps are expensive, wait till you see the price of the optical engine. My dealer told me they run around $750.00! If this is the problem, I'm hoping they will cover it under warranty as the TV is less than 2 years old.

SOURCE: Tv Shuts off occasionally 1min upon power up shows red lamp light

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

SOURCE: mitsubishi wd-73736 bulbs buzzing noise

The Ballast that ignites the Lamp could cause the Lamp to fail and/or cause a buzzing noise. That being said, the Color Wheel in the Optical Block assembly could also cause a similar symptom. If Mitsubishi would be willing to help with the Lamp cost, I would call a local Mitsubishi repair facility to install it and see if the noise is still there and find out exactly what is causing it. Mitsubishi Customer Service Phone number is 1800-332-2119.
I hope this helps,

I just replaced the bulb last week, yet this time the TV will still not turn on and all three lights are still blinking.


It is possible that the replacement lamp is bad but more likely the TV has a protection mode that triggers wen the lamp goes out. Check the manual for ways to reset the lamp usage back to zero or a function that needs to be manually reset when the lamp is changed.

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


HI,

Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

Turns on and off green LED flashes until TV turns back on.


this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.
