* * *Service mode chassis UA-1 SHARP
On the chassis UA-1 carried three models of vehicles SHARP, in the Russian market
submitted by: 21A1-RU 20A1 and-RU, 21A2 RU. The second of these, as its name
model significantly, applies to the value of CRT screen diagonal 20 "
and two others - 21. "The difference model 21A2-RU, reduced mostly to
application of the two heads of dynamic Instead of the one in the models and 21A1RU 20A1-RU.
The main feature of all three models is the use of integrated
ultra chip IX3368CE, encompassing both a control processor and video processor.
Consider the service mode chassis UA-1, which is used to adjust
and adjusting the sound and picture after the work
repair (change of control of the processor, volatile memory chips, etc.).
To enter the service mode of short duration (1 s) is bridged
a jumper between 124 and 122, located on the main board or
button press JWS remote staff. The microprocessor in this mode
service becomes which of the seven submodes is:
• AGC & GEOMETRIC
• WHITE POINT ADJ MODE,
• SUB ADJ MODE,
• Y-DELAY ADJ MODE;
• OFFSET ADJ MODE;
• 1C OPTION MODE;
• MISC OPTION MODE
To transfer from one sub-modes to the second button is pressed CH DOWN / UP
Remote control or front panel. To select the desired sub-modes pressed the button
VOL DOWN / UP remote control or front panel. To select a submode
(See Table 1.) Apply button CH DOWN / UP remote or front panel.
With the VOL DOWN / UP buttons or remote control panel, change the front setting selected.
To exit the service again short-lived (1 s)
bridged bridges 122 and 124 together. The microprocessor thus returns to normal.
Initialize non-volatile memory chips.
The initial values of all stored in the memory chip
volatile and are recorded at the factory prior to it
(Tables 1 and 2). To restore the initial settings,
In particular, after the change of non-volatile memory chips,
perform its initialization procedure.[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
To do this, the jumper is bridged 122 and a 124mezhdu include machine
network switch S701, and after approximately 1 s after this
bridge opens. Control parameter values according to Table. 1.
Table. Two options presented, the user is available in the ordinary
mode system and their values after the initialization of the nonvolatile memory chip.[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
