Ws-55511 green light changed caps. where is pico fuse located ?

I am the one here who first posted about taking the front keyboard out; if you replaced the caps in the DM unit and or pico fuses and still have the 'blinking green light of death" consider sending the board unit to PTS electronics.

You can get a quote from them for the repair and they have a 800 number; if you tried the usual things and it does not work go that way. Even with the factory service manual and schematics you will find it nearly impossible with the Unit in the set to take voltages and troubleshoot it.

DM unit in correctly working set should cause set to have blinking power light for about 70 seconds and then go out--it is DM booting up---if it does not stop blinking either a problem with DM or connections where it plugs into main board.

Let me know if you have questions or need help, I am here to help

Check the two green pico fuses F9A04 and F9A05 on the "Center Board" if either of those two fuses are blown then convergence ICs are the reason its shutting down with a 22 error code.The pico fuses look just like resistors but dont have color bands and they will be bright green.

u have a problem with the convergen ic , and 2 pico fuse on power supply , this repair normally cost about $300

Thats the error for short protection shutdown. Check The two Bright green pico fuses on the center board for continuity F9A04 and F9A05 if they dont have continuity. The convergence ICs and both picos will need to be replaced.

See my reply to your last posting---The set needs The Stk-393-110 and whichever of the two pico fuses is blown replaced--I have instructions AND photos of what the fuses look like.

Check these two green pico fuses F9A04 and F9A05 to see if they have continuity, if they dont have continuity the Convergence iC and those two picos will need replacement.

Hi,
Check resistors might have cold solder joints are changed resistance values around replaced STK393-110
Pay attention to faded colored or fried resistors.
You can download service manual for WS-55511 from HERE to get schematics and technical info. (download all 3 parts of file and use WinRAR to extract file)
Good luck.

Convergence ICs and the two pico fuses need replacement. You can get replacements at the following link with instructions.

go to this site and leave them a email with your model number and they will email you the info you require.
