Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

<img src="mas_baz.jpg" /><br />There are three LED indicators. LAMP, TIMER, STANDBY/TEMP. Each Led or combination leds indicated problem.<br />
<ul>
<li>LAMP blinking : The picture will automatically appear in about 15 seconds.</li>
<li>TIMER and STANDBY/TEMP blinking : A cooling fan inside the set is not operating normally.</li>
<li>LAMP and STANDBY/TEMP blinking : Lamp cover on the rear of the set is not properly shut.</li>
<li>STANDBY/TEMP blinking : Check if the ventilation hole on the rear of the set is blocked, because if the inner temperature is too high, the power will shut off.</li>
<li>All LED blinking : Lamp may be defective.<br /></li></ul>It takes about 30 seconds for the TV to warm up, so normal brightness may not appear immediately. The TV has a fan to keep the inside lamp from overheating. You'll occasionally hear it working.<br /><br /><br />
Sorry for the late reply, I'm offline upon purchasing my service. You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.
As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit. However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).
I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown. I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.
The "LAMP" LED light indication still light up,after all the other LED lights indications turn off?The tv projection lamp is dead.Require a new tv projection lamp.
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

If blinks continue without any pause, the main board is faulty.
Symptom: All Front LED indicators are flashing in sequence: Power-->Temp-->Lamp-->Power......continuously Cause: Replace Lamp . This symptom may happen all the time or it may be intermittent. It is normal if it occurrs from time to time, See OG under TV Front Indicators explanation notes. Good Luck, big IRISH.
Tv will not come on...what is the problem
