Have you tried replacing the lamp? If not, I would start there. Also, after replacing the lamp, make sure that the lamp door gets put back on or it will not come on. There is a safety switch that won't allow the tv to come on when that door is off. If you have already replaced the lamp w/ a new one and you are getting the same problem, then the problem could either be on the lamp ballast, or power supply board. Some tests would have to be made by a tech to determine exactly where the problem is. It sure does sound like a bad lamp though.

I recently replaced the TY-LA1000 lamp but I'm getting a yellow flashing light that goes on every 5 secs.I made sure that it was installed correctly and tried resetting the timer by pressing + and - o


Yellow flashing light? Did you get any picture? Bet, not!
It means: your lamp door interlock is not engaged: did you forget to turn the locking knob? Did you install lamp compartment door? That might be the only issue. Lamp timer blinks 'red", while TV works normally. Reset the timer, it's gone, along with annoying message. Yellow means: interlock or thermal protection is off. Try to repeat lamp installation procedure. then, you'll find out your mistake. don't need to remove the lamp. It would be "red", if lamp won't fire up.
good luck,
Alex.

I have a Panisonic PT-52LCX15 I replaced the lamp and now I'm trying to reset the LCD meter, I have tried holding the vol button and the split button and the red lamp light still is on, maybe you could let...


The lamp light should NOT be RED.
The lamp light should be yellow for the lamp timer warning.

There are two ways of retting the lamp timer=
1) on the TV use the vol - button. push until vol goes to zero, then keep holding it down
on the REMOTE push the "split" button

the yellow light should go out indicating that the lamp timer has been reset
if this fails to work,
on the REMOTE, use the "PLAY" button, instead of "split".
you may have to try this a few times to get it to "take". you'll know when the YELLOW lamp light goes out.

However, a RED LAMP light means you lamp is not working or missing.
reseat your new lamp into the TV...and be certain the LAMP DOOR is securely CLOSED.

I have an HL- t50756 and it turns off every 10 minutes


Try to reset the lamp timer. To do this get the remote first shut off the TV. Then on the TV remote (not cable remote ect) press MUTE
then punch in the numbers 182 then POWER in that order, wait when the TV starts up the Factory meneu will appear go to Options press, then look for Lamp Hrs. to see how many hours you have on your lamp TV lamps last appox 2 years average use. 4,000 hrs. Try this, above where you see the hours go to reset or something like that and press to reset blub timer to zero. Your blub might still be ok, but the timer says times up and tries to shut off the TV thinking the blub is bad. By reseting the blub timer to zero the TV will think it's a new lamp. Until it really goes then no picture at all or gets very dark. Try this trick it might solve your problem.

Good Luck!

TY-LA1001-K I replaced the lamp and didnt restet


I have searched and searched on how to reset the timer. Most solutions say you have to press and hold the volume down button on the tv while also holding down the zero button on the remote, or the pip or split button on the remote until the screen display reads that the timer has been reset to zero or the lamp and power button both flash.

I have tried every combination and cannot seem to reset my lamp timer. If you figure it out, please share it with us!! I'm frustrated and can't get it to work!!

Projection lamp timer reset


I need help resetting the lamp timer. Is there a way to reset the timer w/o the remote? We bought this tv as a floor model 4 yrs ago and they didn't have the actual remote that came with it, so they gave us another remote that works. We replaced the lamp but we keep getting the message that the lamp needs to be replaced and the timer reset. Plus the red lamp indicator is still on. We even used a friend's remote (he has the exact same tv) and it still will not reset the timer.
