I don't think Sony is your brand!  Switch to ACME (Wile E. Coyote's supplier).
As usual: Power Supply (only "notes" I have for the "model" are about bad solder joints on the two 9 volt regulators) and Horizontal Output for starters. |

| Hello, I finally was able to crack the case on this TV and take a look. I found a solder connection on one of the 3 leg dual diode ic's that looked like it was missing solder all together. then I re flowed several joints. I did replace one cap that was 35v 2200 uf that tested bad. then I connected everything back up and now I have a beautiful picture. but no sound. This is my question. does sony make a TV that has no internal speakers. I have looked on the inside of this set and there is no speakers. so I don't know if the person before me took them out or if the set came this way. I did notice on the sound board that there is two connections. A white one and and red one. that looks like speaker plugins. I have worked on a xbr before that had speakers floating off of the back of the tube and connected to the chassis. |

Which is it Diodes or IC? Can't be both! (9V reg perhaps  )
I've got a Sony 27" (KV-27xbr50?) uses 3 detachable speakers. 2 smaller hook on thumbscrews on left & right of cabinet and plug into Speaker connectors on rear. Larger Bass speaker sits on top (matches slope on the cabinet back) and plugs into a round plug on back above speakers connectors. |
