Lamp light is lit and TV won't come on

Was the trouble exactly the same before lamp and wheel were replaced?

If lamp comes on for 3 minutes what do you see on the screen?

the more you tell me the better I can assist you.

I have a wd-57731 The lamp light blinked orange. i replaced the lamp turned the tv on and the timer blinks green for one minute and then the lamp light blinks orange again. It won't turn on. Can you suggest anything?

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.

I'm not sure what is brand and model number of your tv but lamp light On shows its dlp tv.
If lamp light is lit that means lamp inside tv is dead/ broken and need to be replaced.
Replace lamp in tv to get it back in business and usually lamp replacement procedure is easy and written in related user manual.

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

This is symptom of weak lamp in TV.
How old is this TV and did you replaced lamp recently?
If not, replace lamp in TV to fix this issue.
Lamp light does not lit solid if lamp is not broken or dead.
Lamp replacement procedure is easy and would written in user manual.
Thanks.

Lamp light lit that means lamp is dead and time to replace it.
If lamp has not been replaced in 2-3 years then its time to replace it. Make sure to buy original lamp for TV safety.

Lamp light lit, that means TV needs new lamp.
Replace lamp in TV as existing lamp is dead/ broken.
Thanks.

Your lamp hours have expired. Try taking the lamp out then putting it back in. The TV will go to a reset menu for the "new" lamp it thinks that you have put in. From there you can reset the lamp hours from the menu. It it doesn't work, the lamp may be burnt, and you have to replace it.

Ballast Verification Process
1. Short out door switch (SP001)
2. Apply AC power and wait till DM module boots
3. Press power switch and observe spark gap on ballast
4. If spark gap arcs, suspect Lamp. If color wheel starts but ballast won’t strike
lamp, go to next step.
5. Measure BP252 on AC IN CBA for +300Vdc. If missing check door switch, cable
from AC IN CBA to switch and AC IN PCB. If correct go to next step.
6. Monitor pin 2 of BT251 for Ballast ON command from Light Engine. If present
suspect Ballast. If missing suspect Light Engine. Pin 5 of BT251 starts at 3.3V
after power switch is pressed and drops to .18V when the Light Engine sends the
start command. No change on pin 5 indicates Light Engine is suspect, change
on pin 5 with no ballast start, ballast is suspect.

Note: Lamp may arc but not start. Pin 5 of BT251 is "LAMP LIT" and goes to 1.48V
when lamp is lit. If ballast strikes lamp but lamp won’t stay lit, suspect Lamp.
