  • TV Manufacturers’ Receiver Trouble Cures December 29, 2011

    1 | Scanned by mbear2k – Dec 2011

    Introduction I found these books to be very helpful for specific problems and troubles as found and documented by the TV manufacturers themselves during the 50’s. I decided they would be helpful to others in the hobby of fixing up and obsessing over old TV’s like myself. Please let me know if you see any issues with the scans or need clarification on something that is not clear/visible in a scan. From the general preface: This is a series of volumes which deal with specific TV receiver troubles and their cures. These trouble cures are the TV manufacturers’ answers to some of the problems that may arise in their particular receivers. After a certain model or chassis has been in the field for a while, certain troubles may occur which are peculiar to that receiver. In an effort to maintain his own good reputation, the manufacturer is interested in keeping his receiver in tip-top working order. Therefore, his service or engineering department evolves a cure for the particular trouble. The question may be asked, "Why doesn't the manufacturer incorporate the cure into future production runs on his own receiver? The answer is that he frequently does. However, it is certainly not possible, with such a complex device as a TV receiver, to hold off on production until every single "bug" has been removed. The fact remains that many receivers are in the field and do develop certain peculiarities of operation for which the manufacturer has a definite tried-and-tested cure. Many of these cures will be found in these volumes. In addition, the development of new ideas and circuitry is unending. These new ideas are conceived by TV receiver manufacturers and many of the circuits can be incorporated into receivers already in the field. Such changes will improve the operation of the receiver, especially under unusual or difficult operating conditions. What is more, in areas of high humidity, in fringe areas, in strong-signal areas, etc., certain troubles are apt to occur. Many of the manufacturers’ trouble cures given in this volume will alleviate these troubles when properly applied to the receiver in question. You will note that these volumes contain valuable information relating to trouble cures and circuit changes which will actually improve the operation of the TV receiver. You will not be given generalized instructions to "check this capacitor" or "check that tube" if a certain trouble appears. Instead, you will be given exact directions as to the specific operation to be performed in affecting the cure. In all cases where components are identified, the manufacturers own circuit symbol is used. This makes it easy to utilize the information given in these pages along with Rider Manuals and Tek-File. A complete index in which trouble cures are listed by brand and chassis or model number appears at the end of this volume.

    Volumes There are seven volumes available (that I know about). Volumes 1-5 cover most sets and were publised between

    1953 and 1954. Volumes 6 and 7 cover newer sets in 1954 and 1955 and include some updates for brands covers

    in earlier volumes.
