Question about Panasonic Televison & Video

1 Answer

When lining up convergance, green lines up in the center, red lines up perfectly with that but the blue is way off. on the single cross and even more off on the multiple cross but mostly on just the right side of the tv causing the picture to have blue "ghost" effect. i just want to know what causes this and an estimated repair cost. the tv was mfg in 1993 and the model number is PT-47WXC43G. thank you in advance for your help.

Hello the problem is down to the convergance ic, there are 2 big black chip that sit on metal frame called a heatsink they are usually located behind the tuner board on the right side of the tv,stk-110 may be the part number, also in front of the ic are some resistors and 2 capacitor at either end these will need to be tested ,
you have to desolder 1 end of the resistor so you get a proper reading on the mulitmeter, it's lot of work but if you can do it yourself it would cost about 40 to 60 pound good luck

I have a Sony KDP-57WS550 TV that has a convergence problem. Based on the symptoms, I'm not sure whether to indict the convergence ICs. In the convergence mode, I can move the red (and blue) crosses,...


With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

How do I adjust the convergence properties on an RCA rear projection tv?


Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

Color problem


Did you try alignment of color convergence in setting up. Try this
1 Press MENU
2 Select SET UP
3 Select CONVERGENCE
4 Select screen mode ZOOM this accesses the center convergence adjustment.Press set/enter
5 Use arrow keys to aline the red cross to the white cross.Press set/enter
6 Use arrow keys to alingn the blue line in the same manner. Once adjustment is complete press MENU to turn the menu off.
I hope this helps if you cant move the red or blue lines you face the same problem I face. I still havent gotton any solutions to my post about being unable to adjust the red line.You could also call Pioneer's help line 800-421-1404.
