Sometimes, as soon as I press the 'power on' button on my 20HD (directly on the projector OR on the remote, it makes no difference) the projector turns on and immediately turns off. The "READY" light is then off and remains off for a couple of seconds. Then the "READY" light turns on again and pressing the power button again then turns the projector on. This problem happens perhaps 30% of the time when turning on the projector.


Any ideas here?


Thanks,

jimj

Some people have reported that this scenario has been caused by the projector not getting enough electricity to start up the bulb. I have mine running off a UPS/Line Conditioner and only have that problem maybe 1 in 20 starts......You may want to try and connect the projector either to a different electric circuit or thru a good line conditioner/UPS.

Possibly your bulb is headed for the Big One. Does your image appear less bright than it used to be? I had continuous mis-fires and got a new bulb after speaking with Sanyo tech. The guy there implied that my one instance of overheat (filters were blinded w/dust - my bad) may have taken the life of my 320 hr. original bulb. Of course, after getting the new $400 bulb, the old one started working again, but seemed dimmer to me. I put the new one in and am saving the old for backup. I'm now cleaning filters at least once/week. There have been lots of theories I've read, but no definitive answer that I'm aware of. I've heard that some early units had a controller glitch that caused failure to start up. You may want to call Sanyo.


Since going to the new bulb, I've not had the problem. It's a bitter $$ pill, though.

Gordon,

Along with all my other issues, I too experienced a mis-fire. The bulb was new, the filters were clean, the projectors on it's own circuit. I simply removed/reset the bulb, and it's worked fine ever since.


I can honestly say that the purchase of this projector has been one of the worst experiences I've ever had as a consumer.


I expected many hours of enjoyment in my intimate home threater.

WRONG! :(

Your pain is evident, Mike! Bummer! Not to be contrary, but despite my bulb issue, this PJ has been one of the best decisions I have made for my HT. Incredible image. Either I'm lucky or blind, but I've had non of the other issues I've seen mentioned. Colors are spot-on over the entire screen. I don't see any problems that would give me the desire to get inside the service menues. I can't even see screendoor unless I get up close and look for it.

If I had it to do all over again today, I would probably buy it again.

Gordon and Mike -


Talk about night and day differences! How far apart did the 2 of you receive your units? I know Mike has had his or over a year now - Gordon, when did you receive yours? My point being, could Mike's unit be from the first run off the production line i.e. (I hate to say this, Mike) received a lemon? I just ordered an HD20 from Daniel/AVS Science (Great Price - thanks again Daniel) and am hoping I have Gordon's attitude a year from now!


Gordon - could you pass along where you found the best spare bulb $$$?


Thanks,


Andre'

Yes, there seems to be some "luck of the draw" or maybe newer models involved? I purchased mine this April.


Having started out with the recommended screen (DaLite High Contrast Matte White) and DVD player (Panasonic RP-82) and then upgrading and SEEING the difference, Andre, I can highly recommend that if you're going DaLite you go with their High Power screen and that you get DVI into your PJ. The Bravo D1 is an effective, low-cost DVI player. Both made huge improvements to my PQ.

Good luck!

Thanks for the info. I have a HiPix/HTPC that will be my viewing source for HDTV. I've installed a DVD drive into the computer and am looping the ATI VGA out into the HiPix for movie playback. I've thought about uprgrading the video card to DVI but I've read the HD20 won't go above 1024 X 768 via DVI. Is this really true?


I'm still constructing the home theatre in the basement and at first, the screen will be a white muslin sheet as I'm trying to determine what screen size will best fit my 17' 1/2" 16' room. I've read the DaLite HCMW screen is the way to go. My guess is I'll go with 106" X 60" (119" diag.) sitting about 8' - 10' back. What are your home theatre and screen dimensions?

My room's 11.5' x 19.5'. I've got a 106" DaLite High Power screen. It was a HUGE improvement over their HCMW, which I first got 'cause it was the "recommended" best screen for this PJ. Wrong. Go High Power. I've had them both and the other PLV-70 owners who twisted my arm to go High Power were RIGHT! For a 106" screen, you will need to mount the PLV-70 at least 14.5' from the screen. That's where I have mine and I'm just inside the limits of it's zoom.


I have no idea about your 1024x768 question. Never got into HTPC or any service level tweaking of the Bravo or the PLV-70. I just know I set the Bravo for 720p and it looks great on DVI. :)

I got mine from the first batch, same as J. Mike's original unit, and it has never failed to fire up on initial button push, with one exception. When I first got it, I attempted to use it with a UPS/filter that was a little under rated for the 20HD's requirements. That was a year ago. Since then, no startup issues.


Hence my belief it is due to high current draw at ignition when sharing a circuit with other devices. Given the number of lamp problems others are having, I would suspect some variability in lamp quality is an added factor though.


Andre -

On the 1024x768 issue, yest eh 20HD will do 1:1 over DVI, although many HTPC and Bravo D1 users seem to be finding 1364x768 works better than 1366.


Go check out the D1 compatibility thread in the DVD players forum and check AndrePacPal's posts. He has done some experimenting with the 20HD and HTPCs as well as the D1 and has some values that seem to work well.

Thanks for the various suggestions (different power circuit and re-seating the bulb). I'll try the power circuit first and see what happens. So far 3 starts without trouble.


If that does not work, I'll move on to the bulb suggestion. I did call SE about the problem and they too suggested re-seating the bulb although they claimed to have not heard of this type of problem before.


Aside from dust blobs and this start up issue, the projector has not had any other problems since I received it a few months ago. The cleaning tips offered here have always cleared the dust, so I expect similar results on the power up problem too :)

Can you elaborate on the huge differences you saw between the Hi Power screen and the High Contrast Matt White screen? I would think with this projectors brightness the High Power wouldn't be needed. It seems like a good idea to have a dedicated electrical circuit for this projector.


Brandon -


I take it by your answer the HD20 will go above XGA over DVI? I'll look into the thread/post. I'll look ino the areas you recommend and see what new info I can find.


Mike -


Why don't you just sell your unit demonized and move on?


Thanks guys,

I can confirm that the PLV-70 will do 1360x768 via DVI, however I have yet to find a cable that can get the signal from HTPC to projector without problems. Approx 30' apart. I use a VGA cable and am quite happy. Did not see much if any difference between the VGA and DVI connection anyway during the limited time I had the cables to try.

There are lots of posts on the benefit of High Power in the monster PLV-70 support thread. I had to be talked to quite sternly by Brandon, JHouse and others to give it a try. I know it is counter-intuitive and flies in the face of conventional HT wisdom, but it works and works very well. I don't want to hijack this lamp issue thread any further, but it's greater brightness allowed my to significantly lower the brightness setting and raise the contrast settings when I calibrated it to the screen (AVIA). Very punchy picture with apparently great blacks. It was a BIG improvement over the HCMW screen that I started out with.

James,

I am also running mine at 1360x768 over DVI. I tried several DVI cables but the Dual-Link 30ft cable from BetterCables finally wored for me. One hint - put the Projector in "True" screen mode and you will get 1-to-1 pixel mapping. The clarity is stunning.


I am using a Radeon 9700Pro to display this. I also use the MyHD DVI model for DVI (using the DVI pass-thru).

That was one of the cables I tried. And to give BetterCables credit, it came closer to working than any of them. Still had sparklies though. But at least with this cable I could compare VGA and DVI at the same resolution and with VGA properly adjusted, there was little to no difference for me. I will admit I was and am running a Radeon 7500 which is not up to the specs of your 9700PRO by a wide margin. Might even be the diference as to why the cable did not work for me. The 9700 might have stronger DVI drive and got through the 30' cable better. Donno. I am likely to stick with the 7500 until a solution for HD recording exists for cable HD and then upgrade my entire HTPC which is just a P3 1GHz and would never support HD resolutions.


Thanks for the info, I had thought that perhaps the card might have been part of the problem, glad to know the DVI CAN work with the right combo. Will likely need it in the future.

Quick update for the record---

Changing to a different power circuit had no impact with miss-starts. I continue to experience them. I am now trying the original power circuit but have reseated the lamp. Time will tell...
