How do I know if I need a new lamp?

I measured 14 ftL in Cinema1 LOW lamp on a 96" ST130 which seemed plenty bright to me. On high lamp is was over 22 ftL. This was at max throw (1.0 zoom).

Either when the picture is getting too dim for your taste or when lamp hours are approaching lamp life specification - for security reasons. 14 ftL is plenty bright for me.

That seems plenty bright to me too. When you drop below 12 foot lamberts in high lamp, or the picture is dimmer in even high lamp than you like, or the projector tells you to change the lamp, then it's time to put a new one in.

^^ thanks guys. That's what I thought too but the unit is saying please replace the bulb and there are 2000 hrs on the clock. Dealer included a new bulb so I'm going to change it now. Wish me luck... I hope it doesn't get too much brighter!

=========================================================

EDIT: yikes! With the fresh lamp I am now getting 17 ftL in low and 29 ftL in high, and this is with white level calibrated!

I was getting a flicker in low lamp which is now gone. The old lamp also had a strange blue shift that was difficult to calibrate out without causing a red background, now it calibrates real nice biggrin.gif

FYI I've been using mine in High lamp, and it starting flickering occasionally around 1900 hours, then it went away.
The projector then started showing the warning after 2000 hours, although the lamp was still fine, unless I switched to Low mode, and it would then flicker again.
Then after 2100 the lamp started flickering in High mode, and that's when I changed it.

Hi, I am in a kind of dilemma. I just purchased a BenQ W1300 (1150$) but found after my purchase that someone was selling a VW95 at a reasonable price (2500$) which is just inside my budget. So I am still able to return the BenQ, but the thing is that I have already purchased screen material for a DIY fixed screen (grey material, so low gain) because of the BenQs average black levels.

Since the VW95 have a low lumen output and much better black levels, I guess I would need to purchase a new screen material again? I am afraid that the low lumen will be a problem.

Should I keep the BenQ W1300 or buy the used VW95 (400 hours)?

I am upgrading from an Optoma HD70 (1280x720, 2006 model) so I guess both will be a super big upgrade for me.


My screen will be 90-90".
Room measurements (H:2m,L:5m,W:2,6m)


**red area will be covered by black fabric, so will have good light control, but not perfect. Window is totally blackout out when watching movies.

I find it very bright even after calibration.

Low lamp, picture contrast 81, 96" ST 130 screen: 17 ftL.

On high lamp it is too bright (at night).

Is this projector supposed to have two bright corners? Top left and bottom right (when ceiling mounted).

There is also a small bright blob in the center only visible on a black background. Dust blob or internal reflection?

Bright corners can be a problem, but with the VW95 it is quite rare. The bright blob in the center when diplaying a black picture sounds like a dust blob.

Thanks. I tried blowing it out when I changed the bulb but I did not disassemble further. I tried focusing on the blob but it remains a blob, not sure where it would be, perhaps between the lens elements? Optical block looked very clean with flashlight.

Do you advise removing the chassis cover and blowing it out? I find the fan is getting a bit noisy too.

VPL95 - discrete codes for zoom settings

Hi

I have a 2.35:1 screen that masks to 16:9. I use the zoom function on the projector and have the two settings set up. Is there any way instead of toggling zoom memory 1 or 2 that I can have a discrete code for each that is tied to my masking setup.

E.g. When I pick 16:9 mask it auto adjusts the projector zoom as well - at the moment I have to separately mask and then toggle zoom memory

Thanks guys

Rob

I checked my copy of the RS232 protocol document and there are discrete codes for Picture Position memories for RS232 but where they document the IR simulation codes they only list the toggle. Are you, can you, use serial control?

I'll check with my home theater guy to see. Can you send me the codes you mentioned?

Thanks

This thread is very quiet... must mean everyone is happy with the 95ES!

Has anyone ditched a Radiance for calibration in favour of the Sony gamma editor software?

Yes, I think a lot of happy owners. A lot of the nuances of this machine have been worked out in the prior 3500 posts. Are these even still being produced by Sony, or have they now focused on lower and higher end segments?

White balance: custom 3 - required slight reduction in red gain and increase in red and blue bias.
Gamma: gamma 3 - measured as 2.23.
Gamut: normal - close enough that CMS adjustment was not necessary.
Lamp setting: Low - approx 14 fL

Recent calibration at 350 hours
White balance: red and green not changed much, Blue much higher, especially between 30 and 70%
Gamma: measures around 1.75, Other gamma selections show similar low gamma. With Image director I am able to bring the gamma and grayscale back to where it should be.
Gamut: The gamut has shrunk and it is now necessary to use Wide1 and adjust CMS to bring the gamut into spec.
Lamp setting: Low - approx 11.9 fL. Looks like normal loss of brightness for 350 hours.
After calibration the image looks good.


Is it possible that the some sort of lamp defect can cause such a drastic change in gamma and gamut? I might have to get a new lamp to check this out. Sony service was not able to give much information with regard to possible causes, they just said to send/bring it in for service. The projector still has lots of warranty left but I want to rule out the lamp before taking it in to Sony.

Thanks for any feedback.

any news on that topic?

i've the same difficulties getting good results out of my vw95.
image director is the only way to manage that strange behaviour.

Masodes, I recently purchased a new lamp and confirmed that the lamp has nothing to do with the changes. I plan to take the projector in to Sony some time before the end of the year but there is no hurry since I still have more than a year of warranty remaining and I do get good result after spending a few hours with Image Director.

Attached are a couple of screen captures showing the settings and results from my first calibration on the projector in 2012 and a recent measurement using the same settings. For both calibrations RCP is off and the Normal color space is selected. Note the large change to the blue level, the shrunken gamut and the crazy gamma. The results with the new lamp are identical with respect to the gamut, color balance and gamma but the brightness is back up to around 14.5 fL.

After the projector has been serviced I will report on results in this thread.

I just brought this up in my build thread not too long ago. I still love my 95ES! I've had this projector for 3 years now ( 2 years 11 months to be EXACT ) and have not yet changed the bulb. The picture is still very sharp and the colors great. I love the lens memory though I have a personal hatred for films which use multiple aspect ratios. (Not the projector's fault) I initially did have an issue with the lens memory returning to a position just off of where I "recorded it" but I was able to get around this by memorizing the position a couple of ticks beyond the one I wanted. I was also able to figure out all of the controls over the serial port to control it with my ipad. Very quiet operation as well! It has been great in every way. Even years later I have no regrets. I may upgrade to 4K in the future, but I still see no reason to right now.
