Good Day;

Your TV has "poor" connections on the Convergence IC's. Please get repaired B4 you have total part failure and more costly repair.

Good Luck, big IRISH.

This kind of problem occurs due to failure of convergence output chips located on main circuit board of tv and replacement of convergence output chips will hopefully solve your tv problem.
Soldering work is involve to replace these two chips so have local tv repairman for that job if you are not familiar doing so.
Thanks.

I have 3 thin lines red, green,blue at the top of the screen, from side to side and slightly arched. I tried the convergence, but it didn't help. Is this a costly repair or can it be done myself?


It is alignment problem & needs lot of patience, expertise to align LCD panels. To align slightly loosen the screws on red & blue panels. Switch on the TV with input source as computer as it has steady graphics. Align for red & blue by slightest movement using light taps with screwdriver sideways. When you are satisfied, tighten the screws. If it is one pixel height line, just neglect it. That much error can be expected.
WARNING: If you are not sure, do not carry out the alignment. Otherwise it will go more out of alignment.

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

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

PICTURE IS NOT ALIGNED HAVE TO TAP TV TO GET IT CORRECTED


since you have mentioned that you first tap the tv set for it to work well, it has obviously loss connection/ cold solder... check for cold solder and reheat it, this will solve your problem...

JVC big screen t.v.


convergence fail. replace convergence ICs with stk-392-110 can be accessed through the front. take off the speaker grill and panel behind that. there will be a large heat-sink under the picture tubes that is the convergence power board. disconnect all cables(mark any that look the same) going to and from that board de-solder the amps --- replace any burnt or open resistors--- plug everything back in turn the tv on and adjust any alignment needed in the regular tv menu.

3 images in different colors-42 in Sony projection


So this is a rear projection TV.

Chances are the tubes are out of alignment. When cleaning or anything never move the tubes as it will be hell to get em back properly.

In the back you can take off the rear panel and move the tubes to partially re-align the picture.

This is generally followed by a model specific procedure using the remote to bring up alignment grids to finalize the picture alignment.

The reason for the 3 colours in the picture are that the rear projection units use Red, Green and Blue tubes to create the one colour picture.

All in all... When I messed mine up it took about 2 hours to set it straight again.

Now I just have to fix my flashing screen problem and i'm set.

Pincushion Picture on a big TV screen!!!


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.
