Never noticed it on mine,I have been pausing it on a few dvd's trying to get some pics and it all seems stable and flicker free, my source is a PS3 using bluray dvd's.
Is it noticeable on normal playback and from multiple sources?

Hi. My HD65 doesn't appear to flicker. The fact that you are seeing it mainly on one side of the screen would indicate its not a bulb problem as that would affect the whole picture. Have you got the AI feature switched on or off? and does the flicker occur using different sources and inputs?

Mine was doing that... and I was beginning to get worried. Top left like you say. I fiddled around last night and found the Tracking /Phase options.... if you read the manual they say that they can sort out a flickering image.

It seemed to fix it last night, and I went to sleep very happy. Will check it later though. I tweaked both with no real knowledge of what I was doing, until it stopped.

havent tried multiple inputs just ps3 bluray. i too saw the phase and tracking options will have a play tonight thanks guys. also will check the AI although i think its off

Hmmm, mine is still flickering. It is kind of sporadic. Clutching at straws... possibly random questions:

I sit to the left of and level with the projector.
I allow 5-15 minutes warm up.
It eased off after 1 hour, but returned. Linked to attention?
Lens is dusty on the top half, but reluctant to touch lens.
Using Xbox HD (non-HDMI) cable

I have not seen it with games, but that could be down to lots of changing colours and movement. Possibly attention/perception.

If I make a load of changes in the menu, it seems to stop for a bit. Maybe flick between a few modes and then back..

AI is disabled in general.

To stop the flickering.. increase the brightness, either flicking to Bright mode or shifting the brightness right up etc.

Then: Shifting the brightness down, the flickering suddenly starts again at a certain point. It is not gradual like something you become aware off, it clicks on and off clearly.

Could this be an auto-iris issue? Or something? Image AI is off.

It still isn't all the time.

just noticed this myself, I decided to do a search and came across this thread.

only got mine today, i have it plugged into the pc and i have only noticed it flicker a few times, when the screen was mostly white.

watched a video for an hour and it seemed fine.

did you guys get it sorted? or am i likely to keep seeing this?

pablored · 05-02-2008, 5:54 PM

Well, mine kept flickering. It was pretty annoying.

To cut a long story short, it is with Optoma (RMA). Awaiting parts still (after a week) so I guess there is a shortage of parts as well as actual units. At least it shows they found something wrong that is going to be fixed.

I was originally concerned that it was just my eyes and the 50Hz refresh, but for that it would have had to be constant. I also had multiple people with differing eyesight view the image... then I rang Optoma. They arranged for it to be collected from me. I was originally told 5-7 days.

I wish they had told me I could have had a hot swap temporary projector, the xbox is getting dusty.

All that said, If you are connecting to a PC it might be a different issue. Maybe the Tracking and Phase options will work for you, or there is some graphics tweaking to do??

I'll report back when mine finds it's way home.

I've just started noticing this too.

It does seem a bit sporadic though, I can get through a few mins of Pro Evolution Soccer (Ps3) and then I start noticing it. Exiting the game I then notice it on the PS3 menu screen.

Switch to something else (e.g. Ratatouille Blu-Ray) and I don't notice it. When I then quite the blu-ray it appears to have stopped on the PS3 menu screen too.

Question is should I send it back for fixing?

pablored · 18-02-2008, 12:26 PM

Since my projector came back I have not noticed any flickering. However, I have only played a game or two on the xbox and watched a short film, so i'm reluctant to say it is perfect yet... but I am very hopeful it is sorted, and very glad it is back.

According to the tech guys, it has had a new colour wheel... and then when it was going through QC it ended up getting a new lamp as well (as the first one failed the check).

Only downer is since coming back the lens is now a little loose, such that when I focus the image with the dial, the picture can sometimes shifts left and right/up and down as well. This would probably be more annoying if I had a screen, and I'm not sure I fancy loosing it for another period of time.

If you do send off for repair, ask for a hot swap. It could end up being longer than the number of days they quote. Good luck!

jonhilt · 18-02-2008, 1:25 PM

Actually looking at it I could still take this back to PC World where I bought it and get them to swap it (I think I'm within the time allowed for that)

The Question is which is the better option? get a new one from the shop or get Optoma to fix this one for me?

zzzzfletchzzzz · 04-07-2008, 11:23 PM

mine is doing the same only when i but my pj lamp on high setting the flicker stops really starting to do my head in

first the flicker wasnt so bad now icant but my pj on eco mode tried 14 hour's on high setting as suggested in another thread but its getting unbearable was really liking a 67ins screen i think i will go back to a 27 inch lcd tv

Treguard · 12-12-2008, 12:04 PM

I'd sent mine off at the start of November with the same flickering issue. They'd replaced the lamp driver and the bulb. It was fine for about 3 weeks and then the flickering slowly crept back into being noticeable. So I've sent the RMA form off and will be waiting for it to be picked up again.

I hate to think of the cost to them (it can't be far off the original cost of the PJ). On the upside though, the flickering isn't as bad as it was before.

anibap · 12-12-2008, 12:38 PM

Flickering is quite normal on some lamps and it mostly happens in the first 200 hrs. After that the bulb settles down and it goes away. I had the flicker on mine as well around 65 hrs. But after few days it went away. In high lamp mode you may never see it.

if it persists after the lamp run in period contact Optoma.

Mildoo · 12-12-2008, 12:44 PM

i only really notice it on mine when i connect my pc to it, and have it on a page like google were it is all white..

dont notice it on other web pages that are not brilliant white nor on my ps3.

Anim · 12-12-2008, 1:14 PM

As Anibap, my Infocus In78 flickered for first 140 ish hours, most annoying but now im into 200+ hours ive not seen it flicker at all (and I watch it every night)

Unfortunately mine is flickering again, pretty much the same as last time. The problem had gone away and has only recently come back and became an issue. Problem is the lamp is older than 6 months so I hope they don't replace that. If they do try and charge, I'll argue the toss that it was a fault that has been there from the start (same flickering issue as reported back in November).

sparkymarky · 07-07-2009, 9:07 PM

not trying to be negative treguard, but if you try arguing that the fault has been there for so long then because you have lived with it for so long, legally you have 'accepted the fault'. of course the shop may not be aware of that principle........
