Reproduction of this document in whole or in part is permitted if both of the following conditions are satisfied:

  1. This notice is included in its entirety at the beginning.
  2. There is no charge except to cover the costs of copying.

2. Introduction

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.


3. When to suspect the one of these chips?

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

  1. Scorch marks, discoloration, melted or bubbling plastic, device split in half, gobs of smoke, 6 foot flames.
  2. Excessive heat. While some of these chips or hybrids like power amplifiers will run hot, they should not be so hot that an egg would fry instantly.
  3. Functional fault. Since many of these parts have quite specific tasks to perform, the symptoms should provide some hint as to whether it is possible for the particular device to be at fault. For example, your monitor no longer syncs properly would point to the sync separator.

4. 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.


5. Device pinouts

This list was compiled from replies to postings on sci.electronics.repair and will be updated as new requests come in. Contributions are welcome. Please email in a format similar to those listed below. If you provide additional comments, your name and email address will be listed as well.


5.1) BA6209 - ECG1716

VCR Motor Driver with braking. Vcc max = 18 V, I max = 1.2 A.

Pin 9: Vz2

Pin 10: Vout 2

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.
