This did not cut and paste well, but here is an excerpt: MODELS: CTC197 Chassis TOPIC: No video after IHVT replacement Cure: Replace JC12128 with a small jumper making certain it contacts both Pin 7 and Pin 8 as in the original configuration. Refer to the below diagrams of the bottom of the main PCB. The locator is around section P-24. The insert at the upper right is a blowup of the outlined area in the lower left portion of the PCB. A different IHVT configuration eliminated the need for connection of Pin 7. However a connection from Pin 8 to the same circuitry formerly connected to Pin 7 was still required. To reduce reworking of the circuit board, a jumper was used to connect Pin 8 with the remainder of the circuit. In later chassis versions, the PCB was changed to eliminate the need for the jumper (See Figure "PCB without JC128 Jumper"). The jumper, JC12128, is extremely small and during IHVT replacement may be inadvertently lifted while removing solder from the IHVT pins. Since the technician may not realize it was lifted, the IHVT is replaced without the jumper in place. Circuits affected when the jumper is missing include XRP, T-Chip Sync (FBP), TV Guide Plus, OSD Sync and others. The most likely failure is immediate shutdown, extreme tearing of onscreen video, or loss of video. Small Jumper, JC12128, inadvertently removed during IHVT resolder attempt.
