Datasheet for STK392-560 and -570?

Does ANYBODY have the Sanyo Datasheets for the STK392-560 and the -570?

I can't find them anywhere.

Is there any issue with using the -570 in place of the -560 as long as the fuses are in place and the original 3.15A value?

What little I could find detailed the difference between the two chips as the -570 had a higher Vcc Max rating of +/- 50V vs 44V for the -560 and the -570 has a higher Ioutmax of 8A vs 5A for the -560.

Thanks in advance.

    I ended up finding them after digging into google searches a bit deeper.



    Thanks.

Did you figure out if the 570 can be used in place of the 560?

My Sansui SV2918 has vertical collapse and no sound.Please help.


Sansui.. Funai made?? Most Funai sets are identical. Find a diagram for a similar TV. Or.. Google the part# of the output IC. The datasheet should contain application data, including a basic schematic of the vertical cicuit.

Replacing STK Modules in a Panasonic Rear Projection HDTV


Hi there.

If you look up the datasheets for the 392 series, you'd find more differences than power and voltage ratings... Using a similar IC (even if it is the same series) may make it difficult, if not impossible, to converge. It's recommended to change the 2 ICs as a matched pair. Since one already is failing or failed, the other probably isn't too far away.

The resistors mentioned are to bias each output stage for proper deflection and must be within tolerance. They're precision blue flameproofs, so if anything really heated up from a bad IC you'd easily catch any browning / burning. Red is IC7001, blue IC7002, and green is split between the two ICs.

Tha advantage getting a factory supplied or authorized distributor part is you know the LOT NUMBER has been approved by the manufacturer. Generics or unusually cheap originals are often rejects from the manufacturer as being out of tolerance.

The originals are only $29 each directly from Panasonic. Why go through all the effort tearing the thing apart twice to save $30?

Good luck, Mark

Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

53swx10b bowed picture


Double check your work for errors such as solder bridges or incorrect resistor placement. Look carefully anywhere solder could have dripped or splattered to cause the bowing. If you entered the digital convergence mode to touch it up, you will have to re initialize the magic focus for it to function. Good luck
