This projector has gotten to the point where it is very hard to watch any movies that has a lot of black in it. Some scenes are just a blob of black. It is only 1300 Lumens and is for sure starting to get up there in age. Right now my setup is 14 feet away and shooting a 105 inch screen. While looking at the newer options I have heard a lot of pro's and con's on the Optoma's. Would I be mad if I went with one of these? Or would there be a lot better choices? The picture quality is very high imo on this RS50u but it is just not very bright and like I said about the blacks. I cannot stress enough how bad they are. Thank you for your time.
 
The RS50 had bad lamps wondering when you last changed yours.?
The original lamps they came with dimmed below usefull lightoutput after around 500 hours.

So if you got a new lamp in, and prepare to change the ballaster, and get it calibrated right, it will look very decent again, specially concidering DLP projector as a alternative, you will need to get a sony 4K or newer JVC if you want something better or on level with the potential of the RS50, but if you dont know how to correct and measure the gamma drop it will be tough.

The JVC never delivered 1300lumen.

Try take your lamp out and snap a picture of it, and a picture into the lamp socket without touching anything, dust filter would be interesting to see as well before you clean it.
 
It is a brand new lamp. Also took it a part and blew everything I could out of it about 4 months ago. It did have a lot of dust in it. Are you talking about Dust filter as in the foam filters on each end? Let me know if you need anything else. Also I am trying to do research on the Ballast. Is there a video or something that would help me dial it in? Also what is the best place to order this? I have some skills from working with arcade monitors as a hobby. Let me know if you want any more pictures. Also wanted to make sure to point out the picture looks great on everything but dark picutres. Thank you for your time.

Yes it could easily have the cap mounted wrong as well, if the projector turs on dont worry about the ballaster, there is normaly no visible damadge on those.

Your lamp is not a original lamp, so its verry possible it only have half the lightoutput of a original lamp, ill recommend this one , i have that in my X3 and it delivers compatible lightoutput to the original lamp i bought as well. I bought and tested multiple replacement lamps, and this was the best cheap alternative i have found for now.

Is there any printing on your bulb, USHIO/ Osram / Phillips ??

What lamp mode and iris setting do you use.?

Well I have it in pieces now. I had it on High settings and I believe Film was the brightest. I have tried the other presets and played with the black. The Bulb is straight from China. No names on it at all. Here are some pictures of the screen and bulb. I am looking up the Cap thread now.

The only thing I would not understand is if it was the bulb, why does it look so good on all other colors? Thanks again for all your help. Also the IR board looks like it is fine or has been fixed. I have not had any problems with flickering picture just very bad blacks. The screen does has a spot on it from my kids probably leaving the projector on to long. I would not think this would have done anything else to it but maybe? You might be able to see it in the pictures I posted but its not very bright.

if that bright spot in the middel is the projector ill think its been to hot, and might damadge the polarizing filters, wich might explain the bad black, if thats the case the projector is dead.
The no name china lamps normaly have from 50-70% of lightoutput compared to the original lamp.

Please check the lamp blower, its under the plastic housing that covers the lamp socket, its mounted on a bracket with 2 screws so easy to take up, and please snap a picture of it before you clean it, and be gentle its very fragile, if using compressed air dont let it spin, and only low preasure.

I already blew the entire thing out a couple months ago. I will send some pictures of that area. Also the spot in the middle in that one picture was not it. It does has a hot spot from my kids probably leaving it on but has not got any worse. I will go to a black screen or something to show it better. That bulb you listed was from Europe? Just wanted to make sure and after you see these pictures before I spend the money on one. Thanks
 
So let me know if you want to see the spot. Its a small Pinkish area more towards the right side. Thought it is called a hot spot. Everywhere else is nice it seems. I will wait to see what you say before I put it all back together. Let me know if this is the correct part you were asking for and what is the best way to clean it without spinning.

Yes thats the lamp blower, use low preasure compressed air, and hold a finger on the center of the wheel so it dont spin, i exploded one of those trying to clean it in the projector with compressed air.

Ill expect the spot to be a panel or polerizer damadge from running to hot, most likely due to dust buildup in the ventilation path or filter.
 
Do you think there is a way to fix the black then? Or it could of hurt it when it got that spot.
 
If you have a heat damadge in the optical block, the unit is toast, and not worth spending a single £ on it.
 
What would you recommend for a replacement unit? Something that would be as comparable. The optoma ones are cheap but not sure if they are are crisp ect?
 
Hard to say, all depends conditions and budget, i would never be satisfied with a DLP that most likely have more elevated black than your defective JVC.
 
if you want to maintain some decent low level you have to get a JVC, i would look for a X35 or X500 used with not to many hours on it. It will have more light out than your old JVC and about the same contrast.
Just keep in mind All JVC need a gamma calibration to perform properly.
 
Okay and is there something that can teach me how to do this? Do I need a tool or just to watch a video on how to do this? Thank you so much for all of your help.
 
As i told you a JVC X35 or X500, ill concider mid level, or in comparison what new projector you get to the price its high level.

Just calculate the price of a new original lamp and a professional calibration, and calibration is needet no matter if its new or used, as they all develope a gamma drop early, and most people never get it fixed.
