Approx. every 45 secs, it pulls down about 3/4 inchesthen will lock back in. No vert. jitter. -HQ COMMENTS: Copyguarded tapes can and often do cause problems. Thesolution w | ||
Sony | KP5000 | OVERALL GREEN TINT ON UPPER 1/3RD OF PROJECTION SCREEN | The upper 1/3 of the screen has an overall green tint to thepicture/program material. I have also seen 2 other KP-5000 projectionsystems recently with the identical problem. -HQ COMMENTS: Please clean CRT surface. It will be necessary to removelens as | ||
Sony | KP5000 | INCORRECT P/N FOR C5304 IN S/M, CORRECT P/N IS 1-130-121-00 | Part number listed for above capacitors shows 1-129-935-00.This part number is for a 500pF 1.5KV capacitor. The correct part numberfor the capacitors is 1-130-121-00. -HQ COMMENTS: We sent the report to correct service manual. | ||
Sony | KP5000 | PROJECTION TV VIDEO SCREEN CLEANER | When applied, the video screen cleaner left streaks on thescreen which could not be removed. Also burnt and irritated his hands. | ||
Sony | KP5000 | NO CHANNEL LOCK, REPLACED Q2207, Q2208 | When programming the set, tuner would not stop on thechannels. We found a constant H (12V) at Pin 4 of IC2202 (Neon Drive).We traced the problem to a leaky Q2207/Q2208 sync detect/clamp circuit. | ||
Sony | KP5000 | CONVERGENCE CHANGE, REPLACED GREEN CRT | When setting unit up for convergence by placing hatch patternon screen, the set would set up nicely. Then when switching the crosshatch off, the pix looked severely mis-converged. Closer inspectionrevealed that only the green was mis-converged and in v | ||
Sony | KP5000 | COLOR DISTORTION | This unit would change the width of the green raster by twoinches when going from min to max brightness. The unit would alsoconverge OK on internal generator and then when it went back to video, theunit would be misconverged but would still check OK on | ||
Sony | KP5000 | OUT OF CONVERGENCE | Green would go in and out of convergence as the green tube wasarcing. Also brightness level change would affect size of green pictureproducing misconvergence effect. | ||
Sony | KP5000 | PICTURE DISTORTION, LOOSE SCREW ON HOR DRIVE TRANS. Q5104 | Intermittent horizontal sweep problem causes sweep to collapseand burn a vertical line in the three picture tubes. | ||
Sony | KP5000 | DEAD, REPLACED MICA SPACER UNDER VERT OUTPUT TRANSISTOR | 2.5 amp fuse on B+ line would blow every 7 to 10 days.Replacement of the fuse restored operation and hours of testing providedno clue to problem causing fuse to open. By by-passing the relay witha jumper and using a variac, increasing AC input to 130V A | ||
Sony | KP5000 | POOR PURITY | Color purity problems around edge of picture. Problem wascaused by flaking of phosphor edges on all three CRTs. | ||
Sony | KP5000 | INCORRECT FUNCTION FOR TUNING, Q2211 LEAKY | During programming unit would not stop on active channels inone direction from low to high. |
