Great Idea To Solve Sony Push Power Protect HBD-TZ210 Problem
Customer sent to me this Sony HBD-TZ210 home theater system with the complaint of “push power protect”.
In fact this kind of problem is very common in home theater system and mini hi-fi. You can read my previous article about push power protect in Sony Mini-Hi-fi in the below link:
Once the cover was removed I could see the power supply board, main board and the main amplifier section-see the photos below:
I focused on the sound and pre-amplifier board and resoldered all the ICs but the problem remained the same.
The next step was to remove all the three sound ICs to isolate the problem. The sound IC part number was CXD 9965 TN and available from the local market.
After removal of the sound ICs, I then powered it up to check if the error message (push power) still display or not. I was happy to see that no error message appeared and the player starts to read DVD disk. In fact this is one of the great ideas to solve the push power problem.
I concluded that one or may be more than one of the sound ICs were having problem causing the push power protect problem. Replacement with the 3 new sound ICs solved the problem. The photo below is showing that everything was working fine.
