My jvc rear projection tv has double lines and in differant colors?

The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B 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 it resistors are dead too.These parts on the tv convergence board,must be replaced to solved pictures convergence problems.The shop,will cost u like $300-$350 for parts and labors.

Guns or CRT are probably ok. Your TV needs a convergence IC STK392-120 replacement. Lamp are used on LCD and DLP rear projection TV's. Color wheel are for DLP's. :)

Ur convergence it dead,U know how to solders?Buy a convergence kit,use what in that kit,ur tv should be back to normal.Try this website.Tv repair World.com for the convergence kit.

Start by replacing STK's IC.

Probably the projection guns (my JVC had them fail on me). It started that way and eventually I had a triple image of what was on TV, one in red, one blue, one yellow, and all slightly offset from each other. The fix was new projection guns (thankfully it was under warranty as they were about $300 each).

When A REAR PROJECTION TV has coloured outlines or a 3D image the Convergence Circuits most likely need attention.

Replacing the output amplifiers (located within the Convergence IC's) allows the pictures to line up correctly, and no more color outlines.

This is the most common fault in all makes of rear projection TVs.

Some models of TV require major disassembly and considerable shop/manufacturer's support to repair because of their design that causes other power supply or vertical deflection problems. The poorly designed products require a "bench" repair that can typically cost from $350 t0 $700.

Some TVs are designed for on-site repair and have more reliable circuit design that does not usually cause damage to other parts of the TV when convergence chips fail. The ones that usually allow reliable on-site repair are JVC, Samsung and Hitachi.

It is normal to have some resistors in the circuit burn up or increase in value from the heat (from 2.2 ohms to 5 or 10 ohms). These resistors must be replaced with the right value or the chip may fail again.

This is not a simple repair like changing batteries or a fuse. Reading through the other posts shows many that try and end up with bigger problems.

Your JVC uses STK 392-110 IC's. Misinformed people replace the IC's with other "new and improved" IC's, like STK 392-150. These are devices with different characteristics and require different value resistors in the circuit. Replacing with the STK 392-150 will cause overheating of the resistors and a damaged IC.

If you are in Calgary, I can help. If not, get someone that has experience working on your JVC. My website is below with some costs and explanation.

Good Luck,

I have the same problem on my tv - the colors are seperated - the picture is blury and in converge mode the colors will not line up.
Need to know if I need to go and buy a new flat screen tv.
Any advise is appreciated. Thanks

If the images are different colors (red,green,blue) then the convergence has diverged. Some TV allow re-convergence through the menu screen, older sets my need to be physically adjusted (aimed) to clear this up. a strong knock to the TV may have cause this.
