Question about Sharp XR-10X Multimedia Projector

2 Answers

After 20 minutes of use picture shuts down. (Sharp XR-10X)

Bought this projector (sharp XR-10X) refurbished a while ago and have been having some problems. After 20-20 minutes of use, the picture gets a bunch of what look like "dead pixels" and shortly thereafter the lamp shuts down. After that, it tries to reset itself, but the pixels come back immediately and it shuts down again and continues to do so until the power cord is disconnected.

I thought it might be a heat issue (it seems to happen when the room temperature is higher and the projector feels very hot when it happens). I have tried to use fans to cool it and move the hot exhaust air out of the way but nothing seems to be working. The lamp still has 90% life. One thing I haven't tried is vacuuming the filters. Any help you can offer would be much apprciated.

This projector along with Sharp cust service are very poor quality. I have 2 of these. Both blow the bulbs with 400 - 500 hrs on them. Then Sharp refuses to warranty bulbs. My last bulb blew with 2 days on it & only 6 hrs. Sharp still refused to warranty the bulb (By the way I only use factory replacement bulbs from Sharp). Very poor cust service. They say "bulbs are not a warranty item" Never again will I buy Sharp. If you read all the post on these projectors everyone says the same thing. Sharp knows there are bulb problems, but just passes the problem to the customer.

Use canned air and blow every bit of dust out of every vent and hole. if you want to, you can remove the top (6 screws on the bottom, and the 2 top screws on the back) and blow dust out that way. i could also be a power supply problem. from excessive heat, the capacitors on the ps dry up and don't work as they should, causing shutdown.

New bulb in now wont work - no power - wont turn on to reset lamp


first, make sure you have the correct lamp. the lamp for the xr-10x-l looks like the xr-10x, but the plugs are different (common mistake). make sure you have the AN-XR10L2/1, not the AN-XR10LP/1. to reset the lamp timer (with the projector plugged in but off), hold down the enter, down arrow, and menu buttons and press the power.

Sharp XR-10X projector, but missing the projector bulb.


if you plug it in and turn it on, you should at least hear fans running, then it'll shut down because there is no lamp. that's about it.

Sharp XR-10X Bulb works once then nothing


this is something which sharp didnt foresee!!!!!!!!!!
sharp has two identical models
sharp xr10x & the newer model xr10xl.both the lamps look alike , however both have a different rating & reverse connector!!
i.e both cannot be interchanged!however if u have the old xr10x & if u try to fit the new bulb which is lower in wattage, it will explode in 20 mins
if you have bought a used projector , then u wont know if someone has interchanged the ballast!!
as this model was discontinued 2 years back!!!!
so confirm the model , it is mentioned under sharp name or at the bottom
good luck

You will need to open it up and flip this little breaker switch. It has gotten to hot and tripped itself. Dust it out while you are in there.
