Samsung 52" rear projection tv convergence problem?

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....

• 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.

No,is it not.It a repairable tv.The tv have a problems known as a convergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

Projection sets have two very common problems.

The first common problem is 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

you are reaaly looking for a nightmare messing with the convergence rings to adjust the convergence you need to change the two ics and probly some reistors

Convergence is dead.Try Tv repair world.com to buy a whole convergence board for the replacement.The Samsung/Akai use the same convergence board.

Ur convergence is dead.Must know how to solders?Must replaced 2 convergence ICS and some or all it resistors.Tries websites Tv repair World.com,Tvrepairkits.com to buy a convergence to repair it ur self.The shop will cost u $300 for parts and labors.

The convergence is dead.It cause 3D colors misalign
and clicking chirping noise with no power on.Know how how to solders?The 2 Convergence ICS must change and all it resistors. Tries Tv Repair World.com,Tvrepairkits.com for the convergence kit to repair it ur self.The shop will cost $300 for parts and labors.

It looks like you have a problem on your convergence panel. Look for burned resistors near the STK-* IC's. One or more of the STK-* IC's may be bad. When the resistors get hot they smell but so do the IC's. You can replace the bad parts or you should be able to replace the entire panel then go thru a convergence alignment.

samsungs have convergence ic that heat up and cause tv to shut off but most of the time the colors will be off. Alsp solder connections could cause this on voltage regulators.my guess would be convergence ics cost for repair is 250.00



thanks doctor video

Common problem known as convergence. The most common reason is the failure of convergence ics. these ics fail all the time because there big and get fairly hot. there is a possiblity that it can be reconverged if the convergence cuircit is not damaged
