This service manual is a good copy of the original, complete and fully readable. It is really useful to repair my Tv set following its clear instructions.

I was having a hard time finding the problem with this Mackie 1604 unit. I didn't have a schematic. Went looking on the web and found your site and the price was more then reasonable. Ordered it and within the hour had the manual and within 15 minutes had the unit fixed. Best $4.99 I ever spent. Thank you.

This is a service manual in every sense of the word ( French and German versions of the text are included, as well as English..)
There are explanations of the mechanical and electrical functions, plenty of mechanical drawings, and the needed schematics. The quality of the scanning is excellent - all the component values are clearly legible - and very usefully there are pcb component layouts, so you can find a component on the schematic, and then very quicky pinpoint its physical location on the relevant pcb.
I cannot see how I can give this manual any less than the maximum 5 stars! Great value for money, which will pay for itself immediately. Excellent all round!

Plasma Display PD421
Audio input signal for PC/DVI, DT V, and DV D modes is entered into the audio processor IC, MSP3450G , and audio input signal for VID E O/S -VIDEO, and SCART modes is first selected in MUX 8851 a nd entered into the audio processor. As in other chips, the audio processor (MSP34 50G) uses the SCL and SDA line to control volume, and left/right balance and mono/stereo. The L/ R audio signal sent by MSP3450 is a mplified in the amplifier, TA2 024 (UAU1) and sent to the speaker. TA2024B support 10W(based on impeda nce 8Y ) of output for each L/R.
3. Trouble shooting 1) Diagnosing defective module If the power does not come on or if the module operates abnormally, check module defect. To do this, remove the rear cover and A/V B/D to reveal the module s logic B /D. The following figure represe nts the s/w on the logic B/D. � SW 2001

If the switch is set to internal signals, it will operate without external signals, but the screen will be displayed in full white. Therefore the module operation can be checked without the A/V board. Here, be aware that the pin 8 and pin 9 of the power B /D� s CN802(11p), which is located above the module� s logic B /D, must be shorted and the A/C power supplied in order for the module to oper ate normally. Pin 8 is marked as PS-ON below the connector (CN802). If module itself is tested and it does not power on or the picture is abnormal, the module is defective. When reconnecting the A/V B /D, make sure to change the switch to external signals. - The most common module defect i s the appearance of a black or bright vertical line.
