Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Tv probally needed a new tv projection lamp.This tv has not been change it projection lamp like 1 1/2 or 2 years already?Tv been on and used it like 4 or 5 hours everyday?Yes,than the tv flashing or solid on green LED light is on have a word "LAMP" written on it tv bazel frame?Yes,tv 100% require a new tv projection lamp replacement.

MY philips tv model number 55PL9773/17 WAS TURNING OFF THE SCREEN AND LEAVING THE AUDIO ON FOR ONE MINUTE. THEN THE YELLOW LIGHT STAYED ON. THEN THE LIGHT TURNED OFF. thEN I TURNED ON WITH THE REMOTE AND THE YELLOW LIGHT TURNED ON AND A FEW SECONDS LATER CHANGED TO THE GREEN LIGHT AND THE TV TURNED ON. AFTER A FEW MINUTES, BETWEEN 10 AND 30 IT DID THE SAME THING. NOW IT IS OFF WITH A BLINKING RED LIGHT PERMANENTLY ON. TO TURN IT OFF I HAVE TO UNPLUG IT FROM THE WALL. I REPLACE THE LAMP A FEW WEEKS AGO AND IT IS FINE.

Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

maybe this help you, let me know. good luck

Yes this is the signal for a bad lamp. Other things can cause this. 1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.

Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.

If you here the color wheel spin up and no ticking sound, the Ballast is bad.

The ballast part no. 939P978010

The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

1. Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. 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 3. 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 4. 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 5. 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 6. 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 # 930B929001

What are the labels on the lights? Timer/Lamp/Service and what color is wich?
