Unified Memory Block Diagram z Stream Decoder With the built-in Transport Stream Demultiplexing Processor (TSP), the PWM2030 supports bitstream input in TS format. The TSP can separate the TS into audio and video PES, analyzing the PES header, and transferring the PES to the audio and video decoders. The TSP can also transfer any data from the input stream to external memory.

11. Assembly and disassembly procedure This section covers disassembly and reassembly of the TL20 LCD TV. Removal of external casing, its individual parts or internal components can render the product dangerous. There can be a risk of electric shock from exposed components even when the device is not connected to a Rear Coverpower source. 11.1 Disassembly 1.Unscrew and remove the rear cover. 2.Pull down or out the pedestal. 3.Unscrew and remove the main board cover. REAR Cover Pedestal 5.
7. Unscrew and remove the AC power connector. 8. Unscrew and remove the power circuit board . 9.Unscrew and remove the main circuit board . 10.Unscrew and remove the main base plate. Main Board Power 12.Unscrew and remove the LED board. 13.Unscrew and lift out the LCD panel. 14.Remove the panel support screws from the LCD panel. 15.Remove the panel supports from the LCD panel carefully.
11.2 Reassembly Reassembly is the reverse of the disassembly procedure. When reassembling the LCD TV, note the following points: Η The LCD panel is delicate and care should be taken to ensure that it is not scratched when removed. Do not expose the LCD panel to dust or sharp objects. Η When fixing the M-shaped bracket in place, ensure that the screw holes are correctly lined up before attempting to install the pedestal. Η Make sure that the RC sensor cover is in place before installing the LED board.
