Default Re: Sony KV-1340UB restoration

Well done on repairing this set. A lot of folk shy away from these and other Sony sets. The semiconductors were always tricky with Sonys. Generally, you couldn't use anything other than the correct part. We used to try other transistor types just to see what other parts were required but with limited success. We usually just had to order all the semiconductors, transistors, diodes etc for the part of the set we were trying to repair and hope for the best.

I went on a Sony training course and asked the trainer chap why this was so tricky and he told me that Sony designed each chassis from the ground up including the semiconductors. This was why each set had it's own unique types and why it was so difficult to stock parts for customer repairs.
