Blinking Red Light

On my projector. I plug it in, and the power light just blinks red. Nothing else happens or works. I took it apart and everything looks all right, and the fuse works. But I don't know what could be wrong.

    I plug in the projector, and it will not start. The power button simply blinks red.

    I have the same problem with the blinking light. It has never worked right out of the box.

    I also have the blinking red power light. Nothing else will not turn on at all. The bulb looks good, so I'm not sure if buying a new lamp will fix it or not.

    Same blinking red power light, no fan, no light. In reading other forums, there is a mention of a firmware upgrade. Something tells me this is not a user available upgrade and Sharp gets pretty pricey on repairs with color wheels and power supplies, and of course, just for good measure a new bulb. You'll be looking at $850+ in repairs. Hope someone finds a cheap fix.

    Same unit and the red light now just blinks. The last post are older so maybe someone has a fix now.

    Blinking red light only.

  • terry507 Dec 16, 2008

    I reset the unit according to instructions and it worked fine for about 6 hours and then the sane problem again - switching itself off and that blinking red light which should indicate bulb has blown. Bulb has at least 70% life left. I even took it to lab for repair t a cost of $300 and a wait of 6 weeks and they said they changed the bulb. Then 40 hours later same problem. I think it's a built in problem.I feel I've been ripped off.

    just got my friend's old PG-M20X and I've got the same problem. I briefly (2 minutes) got a green light. Now, I just get a flashing red light. :(

  • wirshad Jan 07, 2009

    Same. It was working fine all these days. I didint use it for two weeks and now it is blinking red power led. 700+ hours left on the lamp. I just got a new screen and all, really disappointing that it died on me now.

I had the same problem with the blinking red light. I looks as if realy RL701 on the main power board is the problem. I removed the cover of the relay and cleaned the contacts. Despite the contacts being worn down it worked great. I have ordered a new relay from Sharp for about $35 to replace it (part # 95CK3102AL001).

Kc5mgc! Your advice is great. We have fixed our problem with blinking red light "power" by cleaning the contacts of RL701. I decide to add photo cause we have some difficulty to locate the RL701. The most problem was to remove the cover from RL701.

    could you please explain how you opened the projector enclosure to gain access to the relay?

  • Henry Rancourt Nov 06, 2012

    I got the cover off and the relays are exposed. I will clean them and see what happens. No need for further research.

I had the same problem with my PG M20x. A friend of mine and I took it apart and found that the main power wire that runs to the lamp ignition, and then to the actual lamp, came unplugged. We plugged it back in and everything works. We aren't sure how it came unplugged, but we assume it may have been dropped at some point.

Problem with Sharp XR-10X The power light blinks red

According to the manual, a red blinking light indicates that the lamp cover is open. Try reseating the lamp and making sure everything closes up right. If the light is still blinking, it is most likely a problem with the projector itself and you may need to find out about getting it serviced.

Blinking Light on Mitsubishi SL4SU Projector

To jmatthews

Both power light and status light a solid red with no response to any buttons indicates the bulb timer has expired. You need to reset the timer by pressing and holding the left arrow key, the right arrow key and the power button all at the same time for a few seconds.

If there are no problems, the projector will fire up, but you must replace the bulb as it will fail soon and perhaps explode when it does.

Take care
