MY gosh we have some techs that dont know what d-ila is???? ok folks just for you. Technology Overview & Description The D-ILA device, a special LCOS technology developed by JVC, is a reflective type of LCD that delivers a greater amount of light than a transmissive LCD panel and is comprised of groups of pixels which correspond to each image dot. Also, unlike conventional LCD panels (in which the switches and electronics are mounted on the same surface as the pixels), the D-ILA 's driving IC substrate is located behind the liquid crystal layer. Because of this, the ?screen door effect? found in many LCD projectors is eliminated almost entirely, leaving a nearly-seamless picture which is very impressive. D-ILA and DLP will be battling it out for the next several years, something that will undoubtedly be good for the market and will result in some excellent "trickle-down" technologies for the home theater user. And IPGMAN call a pro on this DO NOT TAKE THIS SET APART as you could poop off the video drivers off the ribbon cables if you take it apart wrong.. Call a pro ofor youe own good!!! Good luck

Hog wash. If you look there are little doors on each side of the tv half way up. Take the doors off and have someone hold a vacum sweeper on one side while you take a can of air for cleaning computers and blow out the dust .If you notice there is a projector lens down in the middle shoot the air on it . I just did mine other day. Couple little dust bunnies can make world of differance.

You should be able to remove the back cover from the set. You may have to remove screws around the connection area too, as this will be connected to some sort of board inside. I would certainly caution you about power issues, make sure the set is unplugged. Once removed,in most big screens you will now be exposed to a mirror,(the mirror will often be attached to the back cover you removed) and you will see the 3 "guns" red/blue and green. If you are unsure of what to use to clean, go to any quality camera store, find out what they would recommend to clean expensive camera lenses with, this should be safe for the mirror and lenses inside the TV. Obviously you do not want to use anything that could be abrasive. Some sets, like Pioneer, you will want to enter from the front, by removing the screen, this will give you a chance to clean that too. For someone that is comfortable with what they are doing this should take about 1 hour. Good luck.

Spot on JVC hd-ila screen

There are several things that could be causing this. Dust or foreign matter on the inside of the screen, dust or foreign matter on the reflecting mirror or dust in the optical block or light engine. The first two can be fixed by you if you can gain access to the interior. The third will require a technician. If you have had your question answered, please be sure to rate the solution. Thanks!

JVC HD-52G786 shuts off

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!
