Accessing Service menu to fix convergence


How far off are the colors misaligned such that you need to enter the service mode to fox them? If one or more of your colors has taken a dramatic shift in position, especially on any edge, then do not attempt to correct through the menu. If one of your convergence IC's has failed then the colors will not align on the screen. If you try to correct this in the menu, you will only be screwing up all the settings and making the set worse. When the IC is replaced with a new one your colors will still be way off, not because the new IC is not working, but because now the menu settings are too far off. I have been to many houses and spent 45 minutes replacing a burned out convergence IC followed by more than an hour realigning everything the customer messed up.

My TV color has yellow, blue and red shadows n the picture.


Enter Service mode.. Press Menu -0-1-5-7 in quick succession . From there select the convergence option. You should see 3 crosshairs -Red, Blue and Green. Green is fixed but Red and blue can be moved. Align both of them with green and see if the issue resolves. If not Try moving them around and see if the problem is cleared. If not you may have the inevitable convegence IC problem and the IC needs to be replaced. Let me know if that is the case and I will give you the procedure.

Green convergance wont adjust, bowed screen


Green really shouldn't be adjusted, you adjust red and blue to the green. When a color is bowed that indicates that a part or two are bad, probably the convergence output IC's and possibly a fuse or fusible resister. You may need a tech to come adjust it for you because after replacing IC's the adjustments should be done in the servicers menus not just in the consumers menus.

Red convergence is off.


hi there, your problem does sound like the IC's or IC has gone bad, before you change them check the solder connections. If they are ok then the ic.s need changing, do both as the other one may fail shortly, they are usually STK392-110 but check the number on the ic's to be sure. then do the alignment that covers the whole screen, sometimes you get lucky and dont have to go through the fine adjust. hope this helps.

Convergence without a remote control


you will need the origional remote you can get one fast through this link just enter the model number www.replacementremotes.com
its normal after an IC change for the convergence to need adjusting, universal remotes can sometimes do it, but i have only seen that happen once or twice usually they wont have the right feature to adjust then save the settings.

Tuning Promblem


You have the typical convergence problem my friend. This is going to involve getting a service manual, locating the two convergence IC's. Then you will need to unsolder then from the printed circuit board. Then you will need to put heat sink compound on the new IC's before you replace them, then most likely, have to do some touch up convergence alignment through the service menu. If you have no solid state repair experience working on printed circuit boards, play it safe and call in a pro to assist you in this repair. Good Luck

Oh no it is less expensive to repair the printed circuit boards. You should buy only the IC,s that sony recomends you to buy. They will cost you more then a replacement IC will but they are not all alike even if they have the same numbers on them. Go to http://www.partstore.com and enter your model number and look for the STK IC. Don't forget to get some heatsink compound to install on the back of the new IC's before you reinstall them.. Remember to always double or triple check your work and make sure you have no solder bridges or shorts on the board. If you need a copy of the service manual, post your e-mail addy and I will send you one thru Pando. Pando is available online at www.pando.com for a free download. Pando lets you send large files via e-mail and the Sony manual is large. Good Luck
