Excellent service manual includes everything is need to repair this radio-caseete, how to disassemble, wiring diagram, all , waiting time until the download was only a few hours. I'm going to buy service manuals from here, are cheap and very good.Thank you.
;
Good service manual,i saved from scrapping this deck,is now fully functional.Thanks.
 ;
Found this to be the manual included with the original packinging, was helpfull but did not give any detailed repair instructions.
;
Complete service manual, was very helpful in repairing this tapedeck.Thanks.

The service manual was a copy of the original from Wirlpool. The quality was good, all neccecary information was available including the service-codenumbers, so I could order the right part to be replaced for repair.
Downloding was no probem after the payment.
Thanks for the service!

DESCRIPTION OF FUNCTION OF MAJOR ICs
� IC4701 (IXA332WJ) This IC is a QS driver for EVEN. It QS (Quick Shoot)-drives the input signal sent from the DVI receiver according to the temperature parameter setting from the monitor microcomputer. � EIC4901 (IXA332WJ) This IC is a QS driver for ODD. It QS (Quick Shoot)-drives the input signal sent from the DVI receiver according to the temperature parameter setting from the monitor microcomputer. In addition, after QS-driving the H and V synchronization signal and DE signal sent from the DVI receiver, it outputs the H and V synchronization signal and DE signal. � EIC4501 (IXA457WJ) This IC is a liquid crystal controller. It allocate the video data of the 24-bit RGB signal, H and V synchronization signal and DE signal sent from the QS driver (ODD and EVEN) to the left-side ODD and EVEN and the right-side ODD and EVEN of the liquid crystal panel and outputs the control signal for driving the liquid crystal panel. It also generates the control signal for dimmer control. � EIC4303 (IXA345WJ) This IC is a CPLD. Because the QS driver and liquid crystal controller are general-purpose FPGAs, it is used to make setting for each FPGA. After resetting, it reads the program data from IC4301 (flash) and makes setting for each IC through serial transmission. � EIC4105 (IXA350WJ) This IC is a gray scale reference power for TFT liquid crystal. It incorporates ten circuits of gray scale output buffer amp, a CMOS buffer amp and a reference voltage supply. � EIC2004 (IXA3491CE) This IC is a monitor microcomputer. It performs OSD control of the monitor section, detection of the panel temperature through the thermistor, setting of the temperature parameter for the OS driver, setting of the timing for the liquid crystal controller, setting of the dimmer control data, power control of the monitor section, monitoring of each power line, remote control decoding and OPC control.
