    S95E Sony 5.1.2 Introduction of IC GM5321: integrate ADC, OSD, SCALER, MCU, LVDS, convert analog RGB into digital and zoom and shrink scaling output to LCD panel. AIC1084-33M: DC power convert, used to 5v convert 3.3v. AIC1084-18CE: DC power convert, used to 5v convert 1.8v.
  • Page 30 S95E Sony Panel Control Circuit: The high level output from PIN67 of U201 makes Q402 break through, Q203 break through and offer 5V to panel when work well. The output is low level when it’s saving energy state and Q402 break off, Q203 break off, so the panel doesn’t work.

Adapter which commonly consists of bridge rectifier and filter, start circuit, PWM control circuit (TOP247Y), protection circuits and convert to 12V, 5V DC voltage by input 90V-240V AC voltage that provide power supply for each chips in the main board and inverter.

Start-up circuit: After being commuted and filtered, the high DC voltage falls down through R (R904, R908, and R911 series), the start-up carries out when the lowered voltage is supplied to L Pin of IC901 (TOP247Y).
  • Page 35 S95E Sony C Pin of IC901 2. ZD901, ZD902 can be broken down when12V and 5V DC voltage increase, which lead to SCR901 breaks through, then 12 connected to ground and realizes over-voltage protection. Commute and filter output circuit: When D Pin of IC901 has pulse output, which makes T901 work, while being given a low level, and there is a current in the primary coil of T901 with a voltage up terminal positive and down negative, so the secondary coil produces a reverse electromotive force.
  • Page 36 S95E Sony level, The primary coil produces a EMF with its down terminal positive and up negative, and the secondary coil appears a reverse EMF at the same time, then D902, D904 get through accompanied with a voltage output of 12V and 5V through C904, C909 which are used to filter.
  • Page 37 S95E Sony PIN9 of U201 Protection circuit: 1. Over-voltage protection: D203 or D204 is broken down when the output of L201 or L202 exceeds 11V, which increases the voltage applied across R222 or R223.It results in rising the DTC value of U201.When the value falls downs to be lower than surge voltage, the output is shut.
  • Page 38 S95E Sony From U201 PIN10 TO U201 PIN11 OSC and output circuit: OSC is made up of C213 and PT201 and PUSH-PULL circuit is made up of Q209, Q210. They are in alternate working state. R224, R225, R226, R227 are used for starting up OSC. The voltage of Q209 and Q210 adds in PT201, and then it produces high voltage sine wave through LC OSC.
