My tv has a green
All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Here are some pics of convergence problems.
- Screen looks 3D
- Colors don't line up
- One or more colors can't be adjusted when using the convergence menu.
- Screen is bowed or warped.
- TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

I have a 50" hitachi rear projection tv, do i need
You do not need a high def receiver, your unit has an ATSC tuner which is the same thing. You do need to hook it up to a high definition signal. You mentioned that you have satellite. Call your supplier and order the high definition channels if you do not already have them on the downlink. They should be able to tell you if you have them or not. They should also be able to tell you which channels they are (normally the higher ones). Once you have a high definition feed you will have the best picture you are going to get with todays technology.

House was hit by lightning
Unplug the set and remove back cover; follow power cord inside---the fuse should be in a holder and if blown will be blackened inside.
Amperage of fuse will be marked on it and on board next to it; DO NOT BUY REPLACEMENT at Radio Shack, get one from a regular parts dealer, the Generic ones RS sells may blow for no reason.
let me know if you have questions.
