Replaced bulb but tv comes only comes on for about 10 to 15 seconds then shuts down and red light flashes

I would try a new lamp. Lamps have varying qualities & usage conditions may cause varying life spans.So, even though the lamp may be 1 year old I would try a new one first.

Try cleaning the little fans that keep the bulb cool, the temp sensor will shut it off so not to damage the bulb , the winning sound may be the fan going bad or not working like it should.

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

Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

The CLS problem. Im thinking that at least you made a visual inspection of the power suply and the capacitors around it. Then if everything normal in the area then the microdisplay (inside the ligth engine) can be damaged. (when the tv is working normally the microdisplay sends a pulse to turn on ballast and lamp finally.

The sweetkyman: when the fan is bad th tv shuts down imm. (if you unplug the fan when the tv is working normal the computer detects the overcurrent system works and shuts down the set) when a fan is all dirty and tons of dust on it the tv tends to work but after some hours the tv shuts down.

Sounds like the lamp to me. The projection lamps get hotter as they age and the TVs have a sensor to monitor the temp and shutdown the TV if it get too high
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 buy just 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.

Hello pravinp,

Since this is a DLP set, The bulb becomes suspect. I would take the bulb out and measure the voltage in the socket from which the bulb was taken to determine if the socket is hot. If it is I would then take a resistance reading of the bulb, the resistance should be at 0 ohms. If your bulb is blown replace it with the exact type. The TV might be shutting down to prevent further damage from occurring

I hope this helps

Color wheel defective. Replace it with the new designed color wheel. The lamp is ok.

Maybe try removing the dust filter on the back and cleaning it. If I recall correctly the TV won't turn on unless the filter is clean and fully snapped back into position.
