With TV powered off press: [mute], [1], [8], [2], [power]
Television will power up in service mode and GAMMA GAIN1 will be displayed on the screen.
Use [mute] and the [menu] button to move values up and down.
Use the [volume +] and [volume -] keys to move to other adjustements.
Use [add] to save the settings.
If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Adjust Convergence on Zenith B27A11Z


You don't adjust convergence through a service mode on one of these sets. With a conventional CRT, convergence is done by physically adjusting the convergence rings on the neck of the tube, and the position of the deflection yoke near the bell. You would also need a crosshatch generator to provide the required test pattern for adjustment.

I cannot adjust the convergence.


You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

How do I adjust th convergence?


Since you didnt poet a model of the set, there are normally 2 types of convergance, analog and digital.

On an analog set there is normally a keyboard with about 40 pots on it marked with the different colors and picts of the scews they will adjust

Newer digital sets will have a service mode that you will need to enter and or have a service remote control to make the adjustments.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Convergence settings


Key Functions
7,8,9 = select R, G or B
+100,0,PRE-CH = mute R, G or B
INFO = test/normal
4 = shifts from point to line, grid move
2 = restore factory
SOURCE = H/V select
ADD/DEL = Save
S.MODE = exit
MUTE = cursor forward
P.MODE = cursor back
Volume +/- = moves convergence left or right
Channel +/- = moves convergence up or down
1 = zero's all convergence settings (ugly!)
U/D/L/R = move cursor
SELF FOCUS = saves the convergence adjustment - do before exiting

Good luck.  I let a sub-standard service joint work on mine - they replaced the OEM chips with a higher wattage equivalent, and I've had nothing but problems ever since.
