sony dvp-s7000 可以點 Mod

有部 sony dvp-s7000，當年買水貨，用110V 牛。因睇唔到有區碼 DVD，放埋一邊一段時間。

剛剛想學 Mod 機，各位前輩可否教吓我呢個新新仔。謝謝！

Well, nearly > 20 years ago, I had built a 6502 Apple ][ computer, but now everything things seem so new to me.

I guess A. is not expensive, and for B. you said it is easy, and I think I can try.

Op-amp - I guess it is Output amplifier, so how much woudl be the cost ? How can I start that ? Can I goto your place to do it ? What would be the tutition fee ?

Thanks...

Thanks ! Any book or magazine to recommend to me, a new beginner in AV DIY before I have chance to join Mod classes ?

Thanks !

Wow, after stduy on the web and learn that
Op-Amp actually is Operational amplifier and the 741 has been very popular.

Then , how should I know which Op-AMP to replace.
And how can I find out the switch settings to make it DVD region free ?

Any useful sites ? Thanks !

Going to open up the case to have a look soon.

Thanks KK.

Wow, after opening the case, try to figure out where the two switches for the DVD Region Code, simply can't find it.

And as this is a 110V player, I am thinking about if I can MOD the power module so that I don't need to use an external AC converter .

Would like to have senior input.

Thanks
