| Sony | KP46S15 RA1 | Dead | Unit has an overheated standby transformer. The 20 volt source is running at 3 volts. | I had tech disconnect the connectors to the ""M"" board M CN653 on the ""G"" board. This removed the load on the 20 volt stand by and let the 12 volt stand by to rise to near 20 volts too. It is possible we have two regulators bad IC652 and IC001. IC001 may have been damaged by too much voltage on its input because of a defective IC652. OR there is a severe load on the output of IC001 the 5 volt standby on the ""M"" board where the 12 volt stand by enters on connector CN053 Pin 1 then to the IC001 a post 5 volt regulator. There is also a 1000 mfd @ 6.3 vdc on the output of the 5 volt post reg. Suggest the tech bring out both regulators and the capacitor C002 as a precaution. "" | Muller |
| Sony | KP46S15 RA1 | Dead | DEAD. Unit has leaking CRT's. Both red and blue CRT's are noticeably leaking with the green showing signs of moisture around the expansion chamber. | Unit will need replacement CRT and the convergence output IC's. | Muller |

| Sony | KP46S15 | CUSTOMER CONVERGENCE IS NOT RETAINED. IC003 | Customer would adj his convergence and picture settings andthe next time they turned the set on the adjustments were lost. SOLUTION: The memory IC for the customer controls is IC003. The memory IC for Dynamic Convergence is IC005.Note: | ||
| Sony | KP46S15 | SPOTS ON SCREEN, REPLACED SCREENS | Have seen two units so far with spots in between diffusionscreens. | ||
| Sony | KP46S15 | RUBBER CAP AS PER I/M PART NUMBER4-050-330-01 | Instruction Manual shows rubber caps as a accessorie, butdoes not give a part number. Nor, does this part appear in the ServiceManual. -HQ COMMENTS: The part number for these caps are 4-050-330-02. | ||
