![]() The ballast is the component that ignites the lamp with a blast of energy. A hot room will make the RPTV overheat and switch off.Ĥ. Room temperature should be close to 72 degrees. Check that the ventilation ports are free of dust or debris. Make sure the TV is not too close to the wall-you need airflow around the entire set. Rear-projection TVs will shut off automatically if they overheat. If you need to replace the lamp be sure to buy a genuine OEM lamp that will fire properly. Check the lamp to make sure the bulb is still working and that the lamp has been properly installed. Your manual will show you what the lights mean. Your RPTV will have warning lights to let you know your lamp is coming to the end of it’s cycle and needs to be replaced. Check the power cable, the wall connection and the back cover to make sure they are secure.Ģ. A loose power cable can trigger the sensor on the back cover and prevent the DLP set from turning on. I mean if that is true and it is decent then I could justify spending $700 instead of $500 but anything more than $700 is just way too much for me to spend.īut I'm not sure I really have the room for it now anyways but I found that site and it looks sooooo tempting.Having trouble getting a picture with your RPTV? Before paying a service technician, review these rear-projection TV troubleshooting suggestions.ġ. So if I really wanted it I would try the build-it-yourself thing although I didn't know you could get one as cheap as $700 I know of home theaters that have 1 and in one case 2, 100,000$+ projectors. Ī new DLP projector of much higher quality than a cheapo lcd can be had for 900-1000$Ī really nice single chip dlp goes for about 15grand and to step up to a 3 chip dlp going to set you back 30grand to start with and up to 120,000$ishĪbove that you get into 2k projectors and such and go up to 160k. Since you can buy a new lcd projector for about 700$ - i'm not sure there are any great deals to be had there - plus lcd's are very heat sensitive and require polarization filters to remove UV (if you build it yourself). for $500 (hell even it if costs double that) it looks pretty darn impressive. They claim you can build this for around $500 ![]() If I can save up enough money I might attempt it with the help of my girlfriend's father as he has some experience in building stuff (though I don't think he knows much about soldering wires which is a skill needed for this project).Īnyways the website sells plans on how to do this for $19.99 but there are forums that you can visit and while most of them are "locked" unless you register by buying the plans (which I haven't done) there are some forums that anyone is allowed to read and one of them is called, "PROJECT GALLERY" and there are some very impressive results there. Unfortunately I don't think I have the skills for such a project but it sounds very interesting. I personal could not watch movies on a smaller screenįor anyone that feels he/she has the skills needed I found this website just recently that has plans on how to make your own LCD front projector. # Front projectors as big as your wall is and you can get hi-res 2048x1536 (7000ANSI Lumens) with the JVC D-ILA # Plasma about 50" max (the cheaper ones are low-res and the expensive (1024 x 768) ones are still not as hi-res as the HDTV signal) The denon sends a 480progressive signal through Neotec component cable. I found you need a good DVD player to give your projector the best picture possible. I have a cheap 59cm Teak TV for normal TV viewing. ![]() A few sites of interest: Ĥ) your lighting enviroment for day viewingĥ) and what your source will be (your picture is only as good as your source)Īs for me, I went for the Infocus X1 DLP Projector and would never go back, my reasons:-ģ) more than I got, but I didnt have the financesĥ) 99.9% DVD (Denon 2200) 0.1% TV (standard analogue) I have a small room, 17 feet wide and the 5X7 foot screen is very impressive. I think the projector type is much better than the rear projection setups. Most vendors have a chart or formula to show how big of picture you can get, depending on the distance to the screen. You also need to set the projector to the size of your room. ![]() Mine was about $350 and if I had it to do over, I would have got either an electric version or at least the regulated retracting type. Most will flip the picture so you can mount them upside down from the ceiling. I have more than 700hrs on my bulb, so no complaints. Mine is about $100US, which is on the low side. They do have fan noise, so check the specs. It adjusts the keystoning both horizontally and vertically, so I am able to put it on a shelf in the corner and get a perfect picture. (It's the 800X600 model) and really love it. I've had a Sony VPL-HS2 projector for over a year now. ![]()
