Section 4 Circuit Operation Description Outline The electrical circuit of UP-895 mainly consists of the following blocks. * Video circuit The input video signal is amplified using a video amplifier circuit to perform brightness, contrast, trap filter, and AGC processing.

The next image data of one frame is written in the frame memory (IC503) when a fetch pulse is input from a system control (IC304) to pin 1 of IC501. The UP-895 uses a 64M-SDRAM (one word is 8 bits) as image memory.

In addition, for semiconductors with ID Nos., refer to the separate CD-ROM titled “Semiconductor Pin Assignments” (Sony Part No. 9-968-546-xx) that allows searching for parts by semiconductor type or ID No. The semiconductors in the manual or on the CD-ROM are listed by equivalent types.
Therefore, specified parts should be used in the case of replacement. 2. Standardization of Parts Some repair parts supplied by Sony differ from those used for the unit. These are because of parts common- ality and improvement. Parts list has the present standardized repair parts.
