I changed the lamp in my sp7210 the new lamp is working fine but.

Hello, make sure all the covers are on correctly, then recheck all the wiring connections, unplug each one and inspect them for a bent pin. Let me know....tks

that model has a history of bad ballasts. you'll need to replace it.

Hello:

Make sure u replace the lamp cover as the safety switch need to be closed to make the set work. If new lamp did not repair your problem , then it may well be the Ballast Board, Sometimes call the Lamp Driver.

Did you reset the lamp timer? If you dont reset the timer the TV thinks the old lamp is still in use.

Hi,

Try to reset LCD video connector, if you have already changed and tried inverter, then check lamp.


Best of luck.

That should be fine to do. Even if the projector did alter the current based on lamp life, the worst that could happen in the lamp would burn out completely. A good projector should have a safety circuit with a fuse to prevent damage to any internal components. You should be fine.

since it has worked 1200 hours or even more since u have been resetting the counter! just change the lamp, resetting the counter does not make the lamp work or not work , it is only a reminder for the user to change the bulb when it should be & that u have some balance hours left to procure a new lamp!
if the brightness is adequate, then it is a ballast problem & not lamp problem!
buy a new lamp as u will anyway need to , fit it & it may solve ur problems permanently!

normally if you change one lamp you have to change them all

take the lap back out and put back in
After replacing the lamp cartridge, when you power on the TV, the message "Did you change the lamp? Press ENTER for Yes, press CANCEL for No"will appear, press ENTER to reset.

Hi there

You must always reset the lamp timer when replacing a bulb.
