one fuse is located directly where the power board goes--set has as many as 6 other fuses inside in different areas--they are pico fuses which means not glass or fuse like in appearance.Set dead with or without power light?

If you have a DVD player you can do a test to see if you have a bad tuner in the TV. Using Red, White, and Yellow cables hook up your DVD player to the corresponding jacks on the back of the DVD player and INPUT on the back of the TV with corresponding jacks as well. Turn on the DVD and TV and go to the TV menu and find the input that you have the red, white, and yellow jacks hooked to and see if you get a picture from your DVD player. If you do get a picture you probably have a bad tuner in your TV (if you are sure your cable signal is good). This setup bypasses the tuner. Let me know how it goes. And if you haven't done so be sure you have the right input for your cable signal correct in the menu as well.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) 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. In some cases the TV will also not show any video. 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....

• 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.

Here are some pics of convergence problems.






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.

one or two of your color guns have gone bad, or the circut that drives the has. There are three guns, red, green and blue. you need all three to produce all the colors, including white and black. in most cases this is not a cost effective repair, unless you have an extended warranty. if it is a sears device, or you bought it from them, they will sell you a warranty to for 200 dollars and then you can get it fixed. you might want to consider getting a new tv

There should be a section in your menu that says "convergence". Select that and use the arrow keys on the remote to align the colors with the white crosses. You will have to do it for each corner of the tv. Otherwise you may have to replace some boards inside of the unit, which can be expensive.

optical engine failure. that technology is called DLP digital light processing and it uses a device called a DMD digital micomirror device that has millions of mirrors onthe face and they independtly move and sometimes they can get stuck or not move and cause spots black or white across the entire picture. i suggest calling customer support for possible repair accomodation

Sounds like the Lamp went out on you. Sorry for the bad news. You can replace it yourself though and save on technician fees. Should be a lamp access on back. remove and replace it... I hope this helps you....

you need to replace convergence chips to resolve this issue.

this set is not compatible with 1080 signal.

need to replace the lamp to correct this issue.
