Sorry folks for a late reply. Was out of station for a month or so. I got the project repaired yesterday. It was a lamp burnout. The lamp is changed as of now and projector is switching on. Couldnt find time to mount it back on the ceiling and check other minute details. Will follow up.

Thanks for all the support!!

The technician advised me that my existing V-Guard SESTO 1000 1KVA UPS for the projector may not be a reliable customer. I personally also had to encounter numerous repairs on this UPS for the past 2 years.

Which is the best UPS for a Full HD Projector?
Is Sinewave a must?
APC only seems to be the available Sinewave option. But it is pricey and just has 1 year warranty and dealers are bit weary about the after sales service.
Please advice.

Wondering how much did it cost for the lamp replacement.

The available option in dealers from Cochin is the model APC BR -1000G, which is pseudo sinewave and costs around INR 10k. Thinking whether I shoudl go for it or not .

I got it done from a friend's acquaintance, he is an expert in projectors and an ex-employee of HCL. Now having his own service. Approx. 8k.

I have a new problem now.
Many spots on the display like lens bokeh when the screen displays black or grey. When the picture is running these are not so evidently visible.
Also few marks on the screen even when the picture is running. I have marked these in the screenshot in white background.

Anybody has any idea?

Looks like DMD chip problem? If yes, this will be expensive to fix
