How do you fix the convergence on a 2003 42 inch big screen tv?

Tv have a problems known as a convergence pictures problems,it is dead.Tv have R,G,B colors lines mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board must be replaced to repair it.To solved tv pictures convergence problems.The shop will cost u like $300-350 for parts and labors.

Convergence is dead.Replaced the 2 convergence ICS,should solved this problems.Try website Tv repair World.com to buy a Whole convergence board to replaced.Samsung/Akai use the same convergence board.

this is a rear projection tv not lcd the color is off because the convergance chips are bad take the board out that has the tow stand up chips attached to heatsinks out order the stk number search for on google then take a om meter check all the resistors aroung the chips replace them also you must be a excellent soilder person or a tech to install and remove these chips

The FL231 fuse is dead.There 3 retangles squares the one in the midle is dead near the right side of the FBT high voltage transformer.the big plastic block with a red wire hook a cap to ur CRT.

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

you have a very common tv projector problem bad convergence


you need stk ic big chips on large silver heat sink.cost to fix from tv shop is around 250 to 400 depends who you get part are only 45.00 dollars

Convergence ICs need to be replaced. post the model number and I will list which ICs you need and where you can get replacements with free installation instructions.

Look in your menu for something called "horizontal static convergence" or just "convergence". Adjusting this will align all three tubes electronically. If physical adjustment is needed, then you have to do this manually inside the Tv. keever

The complete convergence for the Philips projection sets usually requires a clear plastic overlay which fits over the screen and has many precisely spaced black dots. The remote is then used to enter the service mode and converge all 3 colors onto the dots, and then the settings are stored in an EPROM IC. This should only be done by someone with experience with the Philips sets.
