Unless you measured the electrolytics with an ESR meter your check is invalid. It's possibly to see a bulging capacitor and say "that is definitely faulty". It is not possible to say that a non-bulging capacitor is OK. It might still be faulty.

You have a very specific fault with a specific model. Unfortunately, only a time-served TV engineer is likely to be able to diagnose it on-sight and only if he has come across the same fault previously. Otherwise it will have to be tested with the appropriate equipment and knowledge, which is not something that can be done on a discussion forum.
