    Introduction

    Scope and Purpose of this Document

    This document provides pinouts for some of the common integrated circuits found in audio and video entertainment equipment like TVs, VCRs, and cassette decks and computer monitors. A good source for this information is the ECG Semiconductor Master Replacement Guide (or the SK/NTE or other similar databooks).

    Note: the companion document: VCR Power Supply Hybrid Regulators contains similar information for many of the common parts found in VCRs with linear power supplies.

    Much more info on most of these parts can be found on the Net via Chipdir and other semiconductor reference pages. See the links in Sam's Neat, Nifty, and Handy Bookmarks. Consumer electronics sites may have some of the hard-to-find datasheets. For example, for Sanyo datasheets (STK), more info can be found at:

    When to Suspect the One of These Chips?

    The following are valid reasons for investigating the health of one of these parts:

    Safe Troubleshooting

    WARNING: Read, understand, and follow the recommendations in the document: Safety Guidelines for High Voltage and/or Line Powered Equipment before attempting any repairs on equipment that operates directly from the wall outlet (not low voltage wall adapter).

    Testing

    First identify a suitable ground for your multimeter. With the equipment unplugged, test for continuity between the ground pin of the chip or hybrid and the chassis or a metal shield. Don't use the part's ground pin as clipping anything to it increases the chance of an unfortunate short circuit.

    First, check for power to the Vcc or Vss (or whatever) pins. A large percentage of failures will be due to lack of power or incorrect voltages. The suspect device may or may not be at fault. In many cases, a fusable resistor has sacrificed itself possibly due to a short in the suspect part or elsewhere (or opened for no good reason).

    However, note that the 'typical Vcc' or other supply voltages listed in this document or the device's datasheet may not be what your equipment actually uses. Therefore, a voltage that is moderately different than the one listed for the device may be normal.

    Once good power is confirmed, test the inputs and outputs. Obviously, an oscilloscope is generally needed for these.

    Where multiple identical devices are present, substitution is usually an acceptable troubleshooting technique but there is some risk involved as faulty circuitry can blow your 'good' part.

    I would guess that you should be able to monitor Fin and Rin (forward
    and reverse, I would assume) and determine if the commands are correct.
    Vout 1 and 2 should probably be opposites of each other for forward (e.g.,
    +,0) and reverse (e.g., 0,+).  They would be the same for stop.
    
    I have no idea what the Vzs are or the Vreg.

    (From: Anonymous.)

    The HA12002 is designed to be the core of a speaker protection circuit. If all of the inputs are in spec, it turns on a relay via pin 1 to connect the speakers to the amplifiers in a stereo audio system. There is an internal latch circuit to hold off the relay if a fault is detected. Power must be removed to reset the latch. Pin 8 uses an external RC time delay to hold off the speakers when the amplifier is first turned on. Typically the capacitor connected to this pin is charged through a voltage divider, and the components are selected for a time delay of 3 seconds.

    (From: Tuck, Ryan (investbanker@webtv.net).)

    I did a ton of research myself only to find that if you want to replace an LA7835, LA7835-TV, LA7836, LA7837, or LA7838, you are better off using the LA7838 for any of them or paying more for an ECG7104 or ECG7039 instead of crosswiring a SK10085 (which does work. Philips lists the LA7820 listed as being replaceable by an ECG7084 but I have seen it listed elsewhere as an ECG7840 or another transposition of those last three numbers I can't remember.

    STR80145

    
    (From: yonymar@aol.com).
    
    The STR80145 is used in computer monitors. It is called a "Hybrid
    Auto-Switch Module-Doubler". It allows monitors to operate at 110v or 220v
    without having to use a selector switch. At 220v AC the IC allows the
    bridge rectifier to function normally and pass the rectified AC to the
    filter caps, at 110v AC the bridge rectifier voltage is sent to this IC to
    be doubled to the equivalent of the 220v operation, automatically. The
    rest of the circuit operates as if the input were 220v AC.

    This IC senses over current or a DC offset on the output to the speakers.
    In the event of a offset it will operate a relay to remove any connection
    between the amp and speakers so to prevent DC flowing through the speakers
    and damage them.
