Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.

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.

LA7840 Vertical Deflection Output Circuit Features � Low power dissipation due to built-in pump-up circuit � Vertical output circuit � Thermal protection circuit built in � Excellent crossover characteristics � DC coupling possible General Description The LA7840 is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the sawtooth wave output from the BUS control system signal processing IC. Because the maximum deflection current is 1.8 Ap-p, the LA7840 is suited for small and medium screen sets.
TDA6108 Triple Video Output Amplifiers By integrating three video amplifiers in a single IC, the TDA6108 ICs provides a single IC solution for driving color TV CRTs. Each device in the TDA6108 family contains three video output amplifiers in one plastic DIL-bent-SIL 9-pin medium power (DBS9MPF) package (SOT111-1). Using high-voltage DMOS technology, this enables each of these ICs to drive the three cathodes of a color CRT directly, providing a significant reduction in the Bill of Materials for new designs. For maximum performance, the TDA610x amplifiers should be used with black-current control, enabling automatic black current stabilization and removing the need for any external alignments on the CRT board.
TDA8601 RGB/YUV and Fast Blanking Switch Features � YUV/RGB and fast blanking switch � 3-state output � Selectable clamp: � passive (with diodes) or active clamp � Bandwidth greater than 22MHz � Fully ESD protected � Latch-up free. General Description The device is intended for switching between two RGB or YUV video sources. The outputs can be set to a high-impedance state to enable parallel connection of several devices. A HIGH level on SEL (pin 5) selects the video inputs of Channel 2. The IOCNTR control pin (pin 16) defines the 3-state outputs and clamp inputs: � HIGH = 3-state outputs (also for test; active clamp) � LOW = passive clamp at the video inputs (diode) � Sandcastle: the video signal is clamped with an active clamp during the sync pulse.
