| Sony | KV32HSR10 | H OUTPUT TRANSISTOR FAIL, REPLACE T501 | H output transistor was running hot. Checked waveform at H output transistor and found ringing in it. | ||
| Sony | KV32HSR10 | NO PIN CUSHION CORRECTION AND R518 IS OPEN, L507,R518 | Unit came in with a severe pincushion problem, R518 foundopen, the new replacement resistor burned immediately. Found the value ofL507 had changed. Appears excessive AC current passing thru the resistordue to the change of impedance of L507. | ||
| Sony | KV32HSR10 | NO PINCUSHION--CHECK Q505 SILKSCREEN IS WRONG | Complaint was distorted pix, found no pin correction.Servicer replaced shorted Q505, as well as L501, R571, and R518. Still hadno pin correction. While examining Q505 again, noticed that the boardsilkscreen is wrong, it shows L503 on base and D508 cathod | ||
| Sony | KV32HSR10 | "X" BOARD PART NUMBER, 8-752-035-54 | People order part number 1-629-624-11 ( X board) when theyreally need part number 8-752-035-54 (IC-251). This generates customercomplaints because 1-629-624-11 is a blank board. since this is not wantthe servicer needs the servicer has to reorder the c | ||

| Sony | KV32HSR10 | PENCIL-THIN LINES OF INTERFERENCE IN PIX, D-1514 AND R-527 | Screen displayed pencil-thin lines of interference, poor in-terference and set had a high pitched oscillation. I had seen this symp-tom before which was caused by an open R-527. R-527 was also open on theA board. In searching for the cause static resi | ||
| Sony | KV32HSR10 | REMOTE INOPERATIVE, REPLACED C-1701 AND C-1702 OF "A" BOARD | Remote inoperative on all functions. Scope showed remote sig-nal going into IC-1701 but no output. All voltages were present or veryclose. | ||
| Sony | KV32HSR10 | INT. PIC SHRINKING/TROUBLE SHOOTING TIP FOR POWER SUPPLY | I have had several XBR sets with complaints of intermittentpicture shrinking. The solution was no regualtion of the B+ which waslowering under load. Here is a simple procedure that can be used whentrouble shooting this type of failure: Operate the set wi | ||
| Sony | KV32HSR10 | SHUTS DOWN, "F" BOARD Q-651 E-B OPEN | Shut down. Found B+ 135V running between 136 and 142vdc. Iknew either the load was open or our B+ was not regulating. Removed the Fboard from the TV and jumped RY-601. I used a 60 watt lightbulb as my loadon the +135 volt line. Using the variac while mo | ||
| Sony | KV32HSR10 | HORIZONTAL CENTERING: SERVICE MANUAL PROCEDURE, SEE TVP0102 | The horizontal centering adjustment on page 30 of the servicemanual omits the fact that a horizontal centering tap exists as shown onpage 36, the F board.
