Sony | KPR46EXR15 | MECHANICAL SEALED TUBE INFOMATION | Some of these units are using the Mechanical sealed type CRT's. -HQ COMMENTS: Serial numbers approximately between 9,002,601and 9,002,660 are using the Mechanical type CRT. All others are theSilicon type. | ||
Sony | KPR53EXR15 | FREEZE MODE IS ACTIVATED BY VCR (SLV595HF) REMOTE RMTV1121 | Using the remote(RMTV112A) from SLV696HF and activiting therewind function causes the KPR53EXR15 to go to the freeze mode. -HQ COMMENTS: We check a KPR46EXR15 in PR along with the RMT-V112A andhad no trouble. We feel the problem is in the micro or ROM. | ||
Sony | KPR53EXR15 | VERY DARK MAIN PICTURE, CHILD PIX OK.,REPLACED IC2301 (E2) | |||
Sony | KPR46EXR15 | DEAD/AUTO SHUT DOWN MODE, REPLACED C1712, AND F602 | The unit is in shutdown mode. Temporarily taken out ofprotection mode. Found no vertical deflection. The negative 18V (F602)was open. Vert. Output chip okay. Found C1712 leaky. Reconnect theprotection circuit. | ||
Sony | KPR46EXR15 | NO PIX, REPLACE CRT | Previously out of focus on W.O. 0698093. Now, no pix - shortin CRT. | ||
Sony | KV27EXR15 | PICTURE GETS DARK INTERMITTENTLY, RESOLDERED R-739 | Picture gets very dark intermittently. It shows color only. | ||
Sony | KPR53EXR15 | SPOT ON THE PHOSPHOR OF THE CRT, OPEN R-898 (N BOARD) | Spot on the CRT phosphor. | ||
Sony | KPR46EXR15 | SPOT ON THE PHOSPHOR OF THE CRT, OPEN R-898 (N BOARD) | Spot on the CRT phosphor. | ||
Sony | KV27EXR15 | NO PICTURE AFTER REPLACING IC-102 (MEMORY CHIP), SEE SB 99 | After replacing IC-102 picture would blank. The same wouldoccur in the service mode. Thus, how do we adjust the unit if we can'tsee the adjustments? -HQ COMMENTS: Follow these simple steps: (Also see SB No. TVP0099).1. Before replacing IC-102, chart d | ||
Sony | KV27EXR15 | NO POWER WITH REMOTE, REPLACED Q-604 | Unable to activate power using the remote. I was able to getmomentary power on via the manual power button. Observed the voltage atbase of Q-601 the relay driver and it went to 1.2 volts then dropped to .4volts. The OVP line was low at 1.4V instead of | ||
Sony | KV27EXR15 | LOSS OF COLOR IN UPPER HALF OF PICTURE, REPLACE D-308 | Very intermittent (location G-13) there would be a loss ofcolor in upper half of picture, especially when program change occurred. | ||
Sony | KV27EXR15 | DARK PICTURE, REPLACE Q-711 ON "C" BOARD | Unit had very low luminance chroma present and predominatelyred. Looked very much like a low screen voltage problem. Troubleshootingthe C board showed 200V on R, G and B output collectors. They werenot turned on. Found Q-711 Base at .22V and Emitter | ||
Sony | KV27EXR15 | DOES NOT RETAIN, OR ERASE SOME MEMORY SETTINGS, ROM IC-102 | Channels 80 through 87 cannot be erased. Trapezoid lookingpicture and top screen sides reduced. When adjusting pincushion phase inservice mode, correction will be achieved but ROM won't retain new settingin memory when unit is unplugged. | ||
Sony | KV27EXR15 | CRT BLINKS OFF WHEN SET IS WARM, REPLACE Q-711 ON "C" BOARD | Transistor leaky E-C. | ||
Sony | KV27EXR15 | NO PICTURE/NO DISPLAY, REPLACE CRT | No picture and no display. Y/S inputs to IC-301 (pins 3 and 5ok). No RGB outputs. IC-301 pin 7 at 0.2vdc confirming IC-301 has pic-ture muted. G-2 voltage ok. IC-301 pins 19, 21, 23 all at 3.8vdc (shouldbe 4.2 - 7vdc), indicating missing cathode sam |
