First my green light started sagging in the left corner, then the red light did tne same thing. can come one help me figure out what to do. I'm about ready to junk it and buy a flat screen but it's such a waste of money. Any one have a clue what I should do and how much it would cost to repair. Thanks.

Hello Sharmy,

This sounds like a convergence correction amplifier problem, but I won't be able to tell unless I see a picture of the problem. If you can post a picture of the problem I can better tell you what is happening. If it is a convergence correction amplifier problem the parts (2 STK329-110 IC Modules) can be purchased for $5.99 each. The problem is the labor, or if the technician ops for replacing the convergence board instead of changing out the parts, This can make the cost go up to $500.00 for the board with the Integrated Circuits installed. If you have a background in electronics you can make the repairs yourself, however if you do not have a background in electronics I would suggest that you get the TV repaired at a qualified TV repair shop.

I hope this helps,

Thank you,

Red, Green convergence lines are wavy

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Convergence issues again, try using the manual adjust with the remote.
you can only adjust the blue and red, if the green is wavy or the Red and Blue won't more then you will need the ICs or CBA changed again.

Green screen with red and blue wavy lines

This is "NOT" meant as "expert" advice...as this is not my area...HOWEVER...I see no one has answered this yet...AND I got some good help from here a year or so ago that worked for me!

When I had a similar "green screen" problem with my SONY projection tv...the guy helped me by having me make "MINOR" adjustments to the red/blue/green etc knobs behind the panel. These were three small black plastic pieces and needed less than a 1/16 of an inch adjustment...try adjusting one at a time and giving it few seconds after each adjustment. It worked for me..at least for a while (till my wife gave it away to a friend because it was "too big"...ah! women!!! LOL)...hope this helps. (NON-expert help!)

Samsung HCN653WX has wavy lines and red and blue ghosting

The most likely cause is shorted convergence chips and possibly a few pico fuses.

RCA HD52W59 Wavy lines

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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....

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. The power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

SOLUTION #1

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

Picture of a set that needs the fluid changed.

SOLUTION

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.
