Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

these TV's have lots of problems. Don't waste your money on repair. But towards new one or you will be constantly replacing parts.
But anyway sounds like a power supply or light eng problem. If all measurements are good then the chassis needs to be sent to Mitsu for repair (approximately 140 updates to it).

Hello
if replacement lamp has done, was the lamp timer reset after replacement? and if the lamp is original, there is either a bad lamp or a cooling problem.

Replaced bulb in Mitsubishi WD-52525 and it still does not work


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.

Viewsonic PJ550 lamp


Problem 1) The projector should put out a burst of 7000-15000 volts to start the lamp, and then immediately drop down to 60-100 vlts to keep the lamp lit. It sounds like the bulb blowing took out your ballast, or the ballast going out took the bulb (uncontrolled current = overheated bulb = boom)

Problem 2) Thats not a problem at all. HID lighting uses an arc to create light, just like welding creates light. Since it uses an arc, and not the heating of metal, there is no filament to test the resistance of. All the bulb is, is a special mixture of gasses and two very durable electrodes, with a gap in between.

Not sound or picture from the TV


If it has been over 2 years on this bulb, I would start there cause it will need one soon anyway.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. However, this is one of the model that Sony has class action lawsuits against them on because it has so many problems with the light engine. See this:
