I currently have a Barco Data 800, a Sony VPH-G70 and a Sony VPH-722 sat in my converted garage, the Sony VPH-722 is currently installed on the ceiling. I wanted to upgrade from the video only VPH-722 to a better projector but was trying to do it on a tight budget £750ish. I saw a Barco Data 800 up for sale on ebay for spares or repairs and bought it for £100 I believe the tubes are okay (blue is a bit worn) but it appears to have a power supply fault. I also spotted a Barco Data 800 going cheap on the Loot website with a failed red tube. The plan was to make a working projector out of the pair a have a stock of spares. In between buying the one off ebay and buying the one from Loot I found a Sony VPH-G70 up for sale for £250. I went to have a look at it. The machine looks in good clean condition with 9500 hours. The blue tube looked completely worn out (heavy burn). The green tube looked worn but serviceable and the red tube is completely unmarked (replaced?) I bought it planning for an immediate replacement of the blue tube followed by replacing the green tube when funds allowed. I ran it last night with a video signal and I now realise that the green tube is unusable the projector was obviously set up incorrectly, the worn part of the tube only covers 75% of the tube resulting in a very visible large green tinted border. I could run the projector over the same worn window area but this will presumably rapidly wear the blue and red tubes and I haven't got room to move the projector back to get the screen size I want. I've had a quick look at tube prices and found refurbished tubes can be bought for $750 + tax+ shipping. My room is 4m long x 2.4m wide I was hoping to use a 16:9 screen more or less the full width of the room. What should I do, replace the tubes on the Sony or is it a bit OTT for this size of room? Should I get the Barco up and running and sell the Sony on? The complicate matters even more the Barco with the duff red tube is now sold! I think the Sony was worth the £250 I paid even with two duff tubes but its going to cost a fair bit to get it up and running. On the other hand if I sell it and run the Barco will I always hanker after the better performing Sony. Hope this hasnt left you as confused as I am. Any ideas comments..
