Convergence service mode
Hello,
I don't know how to deal with the power settings part but the convergence service mode is "Mute, 1, 8, 3, power".
Samsung HCL5515W red convergence problem
sounds like your convergence IC's have fail and possibly a bad dcm. Some of there models have a small board with the ic's them. It may be cheaper to replace the board. But you can repair it if you have proper equipment
No Picture
I took mine out and sent it to PTS Corp. They fixed it and had it back to me in about a week. Cost about $115.

How do I replace the convergence board in this unit?
Yes the board can be replaced, but you may also need to do some touchup alighnment to the convergence, and maybe need to reprogram the magic focus or whatever the ato convergence is called on your set, if it has that feature, Good Luck
Blurry picture
you probably have a bad convergance board you can get one at partstore.com but if the color is realy out of wack you will need the board it is very easy to install even for a novice unplug the set take off the lower back hte board is on the upper right only one screw and a couple of plugs but first try to adjust the lens have someone watch and loosen the wing nuts and turn the lene,s slowly one at a time i started with the red one you need to have the set on when you do this i replaced the board first works great now
Loss of convergence after powering off.
you must enter the service mode and align your convergence and save it to the epromm also activate the auto focus to activate the sensors , power on /mute-1-8-2- / press enter to save and before you exit activate the focus key on the remote ,very inportant to do the last step./g

Replace convergence IC's,then check alignment.
Use OEM quality ==I use Panasonic IC's with no call-backs.

Convergence (red) is out of alignment
In your red convergence you have vertical and horizontal, pin, lines and etc. It sounds like you have a bad resistor in one of the areas. You would need to know which area to narrow down. Are you could look and see the problem, just look on crt board. I would take a can of Freeze and spray the board resistors until it changes then you could narrow down quicker.
RED
to do a proper convergence alignment always use your geen as refferance to work from bring the red and blue to the green also find the center of the screen and on the top and bottom to be sure your geen is centered then start/g

"Red means your set is heading towards being dead" is the general rule I've always followed.
Red means there is some serious internal issues.
There is one thing that might mean its not serious. If you have component hooked up, check the cables to make sure its hooked up properly with the correct colors on the correct color inputs. that can make a huge difference. If you have them incorrectly hooked up it can turn the image all red on your screen.
Otherwise, it appears your set is headed towards needing some service. This is not something you can just fix on your own.
Is your product still under the manufacturer's warranty or an ext. warranty?
Good luck. keep us posted!

possibly other problems on the deflection board your scaned derived voltages are probably missing when a flyback goes it almost always takes out other components or b+ voltages/g
Blue and red lines..
alignment of the covergence board ,you must enter the servicemode to adjust.set on psess mute 1-8-3 .press enter to save your settings.
Triple Vision
One of your convergence output IC's has stopped working and needs to be replaced. This is a very common problem in projection TV's. The IC should be replaced and the convergence circuits realigned by someone with experience in repairing projection TV's.

Disconnect the convergence board and see if the set comes back on. If it does, replace the convergence board or the STK392-040 Convergence Amp IC's. Good Luck
My 54" PCN5425R TV will not turn on
You will need to locate the convergence amp IC's, the STK392-040, and replace both of them. The originals IC's can be ordered here

sears does inhome service, if you do try to fix it, there is usually a board mounted to the back of the tubes (above the others), if it has this convergence board, try unplugging the red connector with the blue wire and turning set back on, if it powers with a 3d looking picture, you have a bad convergence module. Other than that you may want to call a repairman.
HELP Please. Symptoms seem so similar to this unit.
This sounds as if one of your convergence IC's has shorted out. There should be 2 large black IC's on a heat sink, probably labeled STK392-040. There is a small fuse next to each IC that looks like a small resistor. The IC that controls red-red-half green is bad, leaving the blue where it should be. Replace that IC and its fuse and your picture should return to normal.
