Memory structure of this model consists of the followings.1 Set memory2 Status memory3 Picture memory4 Chroma memory5 W/B memory6 Channel memory
* The gamma memory is realized by giving offset to the Contrast and Brightness output values to thedevices in the gamma mode function.
Flow of data is described briefly. When the power plug is connected to the wall outlet for the first time(Standby state), all data that are stored in the internal ROM are written in the NVM (non-volatile memo-ry). When the POWER is turned ON, all the status memory data and other memory data that are requiredfor the present picture are selected from each memory block and expanded in the internal RAM.When any adjustment is performed at this moment, the adjustment data (user mode items) are written inthe NVM (Service/Special Service) automatically triggered by the memory operation.
The adjustment items (W/B, Device Adjust) that can be adjusted in the Service Mode or in the SpecialService Mode, are memorized in the NVM at the time when the user performs adjustment and performsthe memory operation. Note that the factory adjustment data will be lost at this moment.

4-1. Notes on Repair Parts
1. Safety Related Components WarningwComponents marked ! are critical to safe operation.Therefore, specified parts should be used in the case ofreplacement.
[WARNHINWEIS][WARNHINWEIS][WARNHINWEIS][WARNHINWEIS][WARNHINWEIS]Les composants identifiés par la marque ! sontcritiques pour la sécurité.Ne les remplacer que par une pièce portant le numérospécifié.
2. Standardization of PartsSome repair parts supplied by Sony differ from thoseused for the unit. These are because of parts common-ality and improvement.Parts List has the present standardized repair parts.
3. Stock of PartsParts marked with “o” at SP (Supply Code) column ofthe Spare Parts list may not be stocked. Therefore, thedelivery date will be delayed.Items with no part number and no description are notstocked because they are seldom required for routineservice.
4. Units for Capacitors, Inductors and ResistorsThe following units are assumed in Schematic Dia-grams, Electrical Parts List and Exploded Viewsunless otherwise specified.

SAFETY CHECK-OUT
After correcting the original service problem,perform the following safety checks beforereleasing the set to the customer :
Check the metal trim, “metallized” knobs,screws, and all other exposed metal parts for ACleakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part toearth ground and from all exposed metal parts toany exposed metal part having a return tochassis, must not exceed 3.5 mA. Leakagecurrent can be measured by any one of threemethods.
1. A commercial leakage tester, such as theSimpson 229 or RCA WT-540A. Follow themanufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. TheData Precision 245 digital multimeter issuitable for this job.
3. Measuring the voltage drop across a resistorby means of a VOM or battery-operated ACvoltmeter. The “limit” indication is 5.25 V, soanalog meters must have an accurate low-voltage scale. The Simpson 250 and SanwaSH-63Trd are examples of a passive VOMthat is suitable. Nearly all battery operateddigital multimeters that have a 20 V AC rangeare suitable. (See Fig. A)
