I purchased mine about 5 months ago. Ive been researching and playing around with the remote. This will help you on the way. With the set off, press "Mute", 1, 8, 2 then turn the tv on. This will bring up the main settings, dont change any values on any page, unless you write the origonal values down first, because the total reset doesnt return everything to a "factory" preset. Scroll down to reset and press the enter key. I havent come across any owners or service manuals, and support is slim to none. I wrote a review for the same model on a wal-mart site I believe, and it explains adjustments in more detail. If you want to try to figure out the buttons for yourself, while the tv is on, press "Mute 1, 8, 3" this is another set of adjustments for finer detail. If you change an adjustment here and your not sure, just press the exit button. To save your adjustments in the convergence mode, press and hold the enter button, it should flash a few times and center itself on the screen. If you make a mistake in this mode, the total reset I mentioned first should get you back on track. If you find anything out or have a question, feel free to write me at Silverado1st@aol.com

"Silverado 1st" solution worked great for me.The second part at least TV on then press "mute,1,8,3" and adjust useing Volume and Channel buttons to overlap all lines. Side to Side and up and down. Don't forget to hold the enter button down until the TV flashes 3 times then restart TV.

If you bought the parts from sites such as www.TvRepairKits.com go back and ask for there help. It can be many things from bad soldering to blown resistors.

Will not turn on


check the convergance board for open pico fuses located near the stk amps if they are open the you may have a yolk problem as well. also check the blue gum for cloudy fluid this may be the reason the perfect focus got stuck. if you should get the tv to fire up go to the menu then select reset factory in the convergance menu of the customer menu. this will pull the convegance back to tollorance. the trouble is that when the convegance amps fail customers tend to perfect focus the set and each time they do the convegance memory goes further from tollorance. thus failing the ICs once again. check the pico fuses 1st this is a tell tail sign of those two conditions (yolk, or out of tollorance).

Convergence function reads error


Check the 1.8 ohm resistors in the convergence circuit there will be 6 all 1.8ohms, They will be where your STK ICs are
STK392-110s which are Big Black ICs,You may need to replace ICs They are Big Black ICs with STK392-110 printed on them Mats has them 1-800-628-1118

Picture looks curved on screen not flat and straight across. Images have pink and green streaks on them. We lined up the convergence as best we could but its not perfect and the screen still looks curved.


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Red out of focus


You red convergence IC is bad, Have the Convegence IC's replaced,It would be wise to replace them both because if the red has failed then the green/Blue IC will fail soon too. Better to replace them both now then have to do the same again with the other IC.
They are large black IC's mounted on a metal heatsink with part numbers on them the Number on them is the part number should be STK-392-040.

Samsung 42" rear projection HD tv issue


1 they are either rebuilt or a defective returned to stock accidentaly
2 yes securly attaching it helps the heatsinks keep even cooler. no you don't need heatsink grease.
3 if the tolernace is very far out of wack then it woun't take long befor they blow. once you have instaled the new board turn on the set enter mute,1,8,3 then perfect focus on the remote let it do it's thing then shut off the tv and resart the tv and press perfect focus again.

Perfect Focus 2


Use a site like servicemanuals.com and get the service literature for your make/model.Do NOT perform factory reset procedure-that is reserved for when certain parts are changed.You will need the access sequence,adjust info and add to memory step for servicer convergence.Keep in mind--you may have defective convergence IC's.If so,you will have difficulty w/alignment.Use OEM or better IC's no generics!! They won't hold up.
