8320 series color television of Beijing use system of remote control of Toshiba CTS- 130A, CPU is TMP47C433AN 3849, memory is TC89101. Can store only as a result of this machine 32 programs, to use bring inconvenience. 90 increase the number that keep a station after the author alters slightly to this machine, and can keep a station through stage of search of remote controller implementation. Show the introduction to change one's costume or dress the method is as follows:
One, of CPU alter
1. demolishs the CPU of original machine, change its with TMP47C433 AN3888 CPU.
2. cuts off former CPU (34) , (road of 37) foot dispatches from foreign news agency.
3. general former CPU (33) , (34) foot is short receive.
4. is in former CPU (34) , (resistor of 20Ω of a 10 ～ is received between 37) foot.
2, of clavier scanning circuit alter
Disconnect the negative pole of VD716, be linked together VD716 negative pole and VD719 negative pole.
3, of memory alter
1. demolishs former memory, with 24C02 era is changed, go to the lavatory for wiring, can use harder lead connection, make 24C02 suspension is in circuit board upper part keeps stable.
2. general 24C02 (1) ～ (4) foot is short receive and receive to former circuit board memory (5) foot, 24C02 (8) foot receives former memory (8) foot, 24C02 (5) foot receives former memory (3) foot, 24C02 (6) foot receives former memory (1) foot.
3.24C02 whether the key that keeps a station is (of 7) foot receive a standard, if buy the 24C02 that is the company such as AT, ST, BR, should will (7) foot receives former memory (6) foot (namely ground connection) ; If use the 24C02 of company of KOR, KS, should adopt base a 10kΩ resistor is pulled to receive 5V power source on the left and right sides, be in (the capacitance that left and right sides of a 1500pF receives between 7) foot and ground.
4, change high frequency head
This machine uses 330 MHz half supplementary and high frequency head, if place is 470MHz wired system, should change its for completely supplementary and high frequency head, beautiful of picture of author use Shanghai is completely supplementary and high frequency head effect is better, and after changing, high frequency head need not be adjusted.
5, the change after changing one's costume or dress
1. changes his costume or dress after finishing, switch on the mobile phone first, meet sometimes in screen mid upper part appears character of a gules "M" , pass opportunity of the reopen after machine with face plate mains switch, this character also does not disappear. Need to close with the remote controller only right now machine can eliminate, usable also remove this character directly about the remote controller that shuts "M" character function.
After 2. changes his costume or dress, volume, chroma, brightness all turns into uppercase show, the number that keep a station is added reach 90, all sorts of operations and before changing one's costume or dress basic and identical, the conference after just changing a table every time appears make type show "P433" or "N358" , meet namely after a few seconds disappear automatically.
