It is an easy replacement, but you will need an expert to replace the screen. Please do compare the price of a replacing the screen and a new set.Look for a second hand screen.

You are describing one of two types of problems:

1. Red and blue lines around objects and lettering.

2. Background of picture turns reddish or blue (a black and white image will tell you if this is the case.)

Both are fixable but number two should require less than 15 minutes and no parts.

Number one is different: Which best describes your issue?

their are lots of tutorial in photoshop at youtube one of these are in the link below hope it helps thanks. http://www.youtube.com/watch?v=qgsWuru82Dk

Well that all depends on the connections you have.

Check the back of the TV you will see the available input ports that are available I.E component, coaxial, HDMI.
Find one that is available and check if your dvd supports the same type.
Order of quality is HDMI, component and coax last.
Once you have established that you just go ahead and connect the wires.

If my answered help give me four thumbs as thanks!!

Here is a manual as well for the TV.

Its very unlikely that you have a bad tube in this model..that would be very rare...it may just be the convergence or possibly the fluid in the lenses has clouded up. Both are common issues. Read this and see if it helps http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

This is likely due to a fault in the convergence circuits or power supply to these circuits


i will list the criteria required to service TV and projector TV`s first and foremost you require a good understanding of how TV`s work and the ability of reading schematic diagrams, then you require a knowledge of how printed circuit boards are patterned so you can navigate around them to locate possible trouble spots.
then you require
1 multi meter of good quality
1 oscilloscope 20 MHz or better
1 shop service manual pertinent to your type and model of unit you wish to repair
this is a minimum requirement of test equipment you can have

you also kneed a location or locations to obtain the replacement parts you may require to complete the service task.
Now if you have all the above criteria in place then you have some hope to service your unit

a flashing red indicator on your TV usually refers to an internal circuit failure, most modern TV`s have circuits incorporated in the circuit design to protect good working components not involved in the fault from further damage so the set will not power up and an indicator light will start flashing, trouble spots can be anything like power supply under voltage, over voltage over current, no vertical deflection, excessive high voltage, XRAY, convergence failure,, EXT EXT,EXT,
Warning rear projection televisions can harbor in excess of 30,000 ,yes that is thousand Volts

There are and never will be user serviceable components inside LOL

Now if you are ready and require further assistance you may contact me and i will step you through the diagnostic procedures Good luck

Just use windex....works fine

It sounds like your drive jets are out of alignment. Ask your local TV repair places what they charge for re-alignments.

No,this tv it is fixable and still can be in used for many more years to come.This tv have a problems known as a convergence pictures problems,it is dead.Tv problems have any colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv have a dead convergence board to causes this problems.Must have the tv convergence board to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost u like $300-350 for parts and labors.

hi.. if your projection TV has no raster at all, it has problem with high voltage supply. there are two separate power supply inside your TV for audio and for the high voltage for 3 CRT tubes.its very dangerous to service it by yourself.

I would imagine the bottom or top half is black. My first suspicion, the vertical IC has bad grounds and needs resoldering. Do not short the pins together with excess solder! I would certainly start there for repairs. Thanks for asking and show all hands of support!

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

if you have an external box for the signal (like a sattelite receiver or cable box) then you need to see what input it's plugged into.
If it's plugged into something marked AV1 or something like that, that's the input you need to select to get the TV back. The TV input selection is only for when you have analogue cable or antenna plugged directly into the TV itself.

Did you pull off the bottom cover and right below the screen is serveral screws remove all of them screen slides upward then out.

cgail1965,

Convergence problem, See my tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics for help with the repair.

Thanks for using FixYa and for the great rating.

The tv have a problems known as a convergence problems,it is dead.The tv convergence board must require replacing 2 STK convergence ICS and some or all of it resistors too.Fixed the tv convergence board to fixed the tv 3D pictures problems.This problems are very common for DLP tvs and the tvs shops will cost around $300-350 for parts and labors.Will not get a new 50" tvs any kind for this price.

the convergence needs to be repaired

sounds like an issue with the Blue Convergence amp IC. I would try replaceing the convergence Ics.
