Sony Home theater model HBD-DZ650 changing function automatically now repaired.

 I received the above home theater in my shop for repair, complaint from the customer was changing function automatically.

Since I was busy I requested him to leave his contact so that I can let him know when ready. Later I opened the machine.

I scanned around and noted two capacitors with top slightly bulged out on power supply board(S.M.P.S), I used my ESR meter and picked several capacitors too with ESR value out of the range.

I replaced the bulged-out capacitors and others I was not happy with, after testing I noted the problem was now solved.

I notified the owner about the progress and was happy to hear his machine is now working.

Thank you, guys

See you in the next class
