When I turn my tv on, there is a box that comes on and says replace lamp bulb and lamp timer, I changed the bulb but I do not know how to change the timer?

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Check capacitors cp624, cp647 1000uf@35v each. They are in the power supply. Can be seen with bulge on the top. Seems to be a common problem with this model RCA.

You need to reset the "Lamp Hours" in your settings. It is a timer that just runs down, and doesn't know if you changed the bulb. It just needs to be reset to 0.

Web site was no longer available last time I checked. HOWEVER...if you go to www.fixyourdlp.com they have step by step instructions. It is really quite simple. I have changes mine twice in the 5 years that I have my 56" Vivitek. Start out by unplugging the TV. On the back you will see 2 screws to remove the lamp door. Once open you will see the lamp holder which is also held in by 2 screws. Once they are unscrewed the canister and lamp can be removed. Use rubber gloves when replacing the bulb. You will need a phillips screwdriver and a needlenose pliers. There is one phillips screw on the side of the bulb to remove and a nut on top that needs to be removed. Pay attention to the 2 wires connected to these points and be sure to put them in the same position when hooking up the new lamp. Once the screw and nut is removed, you will see a spring clip extended from behind the lamp to the front of the lamp container. It clips in the front and the tention holds the lamp in place. Remove the spring clamp and the lamp will come out. Put your new lamp in place, replace the spring clamp as it was (This is the hardest part because of the tention of the spring and getting it back into the cutout **** for the wire spring), then replace the nut and phillips screw and you are ready to plug it back into the TV. Be sure to replace the lamp box properly. Look at the 2 wire connections and align it with the connections inside the TV. Once inserted, tighten the screws on the box, replace the lamp cover and tighten those 2 screws and you are finished. Plug your TV back in and turn on your TV. NEXT...remember to reset your lamp timer when finished. That is done with your on screen menu. Go to System Info and look for "Reset Lamp Timer". Once there, select "YES" to reset the timer to zero.

the lamp ballast is bad and needs replacement.

CK your Fans make sure they are running or set will not come on.also if you can solder resolder power supply board.

Check that when you turn on the TV the Lamp is striking (turning on).

My thoughts are that you will have to reset the lamp hours counter to make it work, as the TV does not know that you have replaced the lamp. To do this, check the leaflet that comes with the lamp - it should explain how to reset the counter for the lamp hours.

To reset the lamp timer, hold the "enter" button on the tv and the "mute" button on the remote at the same time. Once the menu pops up, hit the right arrow on the remote and confirm the reset.


I would guess that's it's a little too late for this answer now, but for future reference... ;-)

RESET THE TIMER!!!!!!!

Go to the menu and you'll find lamp timer section.
