I need to know how to get into the service mode to try to realign the red convergence. I have been thru the setup menu and this does nothing. I turned the TV on yesterday and the red is all wacky. I open the back of the TV and place a sheet of paper over the red lens and it looks fine (except I get no red hue).
How do I get into the service mode? I had a technician show me about 5 years ago but forgot.

It sounds like the convergence amplifier IC for the red crt is at fault. To check this, go into your user menu and pull up the red convergence. Try to move it up/down or side to side(it doesnt matter). If it moves up and down, then the vertical amp is working. Likewise if it moves side to side, then the horizontal part of the IC is working. If it dosen't move at all, or only moves up/down or side to side, then the IC is bad.
There are 2 large IC's on the chassis, mounted to large heatsinks. They have STK392-110 or some variation of an STK392. If yow feel that the IC is bad, change the ic BEFORE you go into the service mode, as you wont need it if the ic is bad.
To get into theservice mode:
1 make sure tv is in cable mode
2 set sleep timer to 30 minutes
3 tune to channel 124
4 use volume down on front of set to turn volume all the way down. ( writing will appear in the top left corner).
5 use remote control and press the power button.
6 the 7 button on the remote will put it convergence mode.

converge outputs getting tired or limiting resistors opening up. adjusting this incorrectly will make the situation worse keep in mind that overdriving these chips will cause a fold over of your image when you see this carefully adjust in the opisite direction as you may be overheating the outputs
You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.
you have to go into service menu to reset convergence after changing ics.I never posted this because if you do not know how you can shut set down.which chassis do you have ? There is 3 diffenert ways to enter into service mode for convergence.
If you have a problem with the convergence, believe me, going into the service menu and trying to correct it will only give you large headaches, DO NOT USE THR SERVICE MENU UNLESS YOU ARE A TRAINED TECH!!!! Doing so can result in a complete and total failure of this TV set. I service menu is not for any major changes in any adjustment. It is not the cure all. If your convergence all of a suddenly shifted, it is not a service menu issue. Your problem is the convergence amp IC's. Good Luck
