It means either a error or a problem in the convergence circuit. Are colors skewed with red or blue lines around words etc?

This set should also have in the customer menu a way to adjust manually with the original remote--most of these sets there bring up 8 or more crosses and you attempt to adjust each so it is yellow.

if Red or blue will not adjust in some direction at any of the points, you have bad convergence chips.

This model should use either two of the STK-392-040 OR THE -020 CHIPS, I will attach a photo of what typical chips look like.

Let me know what you find, I am here to assist and help.

I have a Jason 400x telescope 306 s that won't focus


You are using too much magnification. I am sorry but that scope will NEVER reach 400 power. This is a complete LIE--- meant to sell the scope. Even in my LX90 8 inch scope we rarely go above 200 power.and then ONLY on perfect nights wityh perfect sky conditions.

The maximum magnification of any telescope is no more than 50 times the aperture of the scope. For example a 3 inch scope is no more than 150 power.

Put the eyepiece with the largest number written on it into the focuser. Do not use the 2x barlow if you have one. Practice focusing with JUST the eyepiece on a distant object during the day time.

"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

Double check the timing marks on the crankshaft and cam pullies. I bet your off by a tooth after replacing the timing belt.

Blue convergence


SINCE YOU HAVE REPLACED THE CIRCUIT BOARD,THE NEXT STEP WOULD BE CHECKING VOLTAGES GOING TO THE CONV. BOARD COMING FROM THE POWER SUPPLY CIR. BOARD.....IF NO VOLTAGE METER,,SOMETIMES, THERE ARE FUSES ON THE POWER SUPPLY CIRCUIT BOARD THAT SUPPLY THE NEEDED VOLTAGES FOR THE NEW BOARD YOU JUST REPALCED...UNPLUG THE SET,,CHECK FOR A BLOWN FUSE----I THINK THERE IS 2 OF THEM--ONE FOR A NEGATIVE VOLTAGE AND ONE FOR A POSTIVE VOLTAGE FOR THE CONVERGENCE BOARD..GOOD LUCK--SORRY, MIGHT NEED A TECH...TUNICA

Perfect Focus


Perfect "FOCUS" is a misnomer.Convergence is the real issue.Enter servicer mode--perform accurate convergence alignment procedure--activate perfect focus as last step to 100% alignment.If you have a High-Definition source,check procedure for that.
