Phillips big screen tv is red and gren colors and a double picture when cut on....how do you fix it

Ur tv have a problem known as a convergence picture problems it is dead.Tv have any colors lines R,G,B mis alignments,have colors shadows picture or 3D pictues look alike?Yes.The tv convergence board it dead have to be fix like replacing 2 STK convergence ICS and some or all of it resistors too.Fixed the convergence board to solved tv convergence picture problems.The tvs shops will cost u like $300-350 for parts and labors.

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 projeciton 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 photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

you have a miss aligned convergence. try to aligned it first.

You need the Phillips DPTV305 - DPTV345 Chassis convergence repair kit which is available at the following link. the kits contain the parts and detailed instructions on how to do the repair.Just click on the phillips repair kits page.

Replace BOTH of your STK ICs will have part number on them they are big black ICs.

You have bad convergence IC's. Replace both the red and blue drive chips. They are easy to spot. They are mounted to large, finned heat sinks. The # on the chips starts with "STK-" and then there are numbers following. Both red and blue use the same part. There are 20 or so pins to unsolder\solder. These parts are available to the consumer from tritronicsinc.com. Good Luck!!

This is a convergence problem and is either bad connections at the convergence ICs or defective ICs. If you can solder, you can repair this yourself. Let me know if you wish to repair this and I can provide you with additional details.

can you post a picture of your screen or send it to my email [email protected] as it sounds like its just the convergence Ics and the 6.8 ohm resistors, but a pic would help me do a accurate diagfnosis.

Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.

The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.
