Title: Hitachi HDR255 PVR problems - Vestel
Post by: Turnip on May 02, 2012,12:02:19

Hi folks,

Have one in where HD doesn't initialise. Checked and found HD 5v ok but no 12v supply. Noticed that TSM9933D (dual P Mosfet) was cremated.

Suspect this is driven by P026H/U2H2/F7324 8 pin chip nearby, where no info seems available. 

Tried for Vestel shematics and found our fave (non approved) Vestel help sites seem have gone tits 'oops'

Notice some on Ebay sold without a HD - could be an option - Chris.

Hi Keith, and thanks.

Found several possibilites for the dual P,  but it was that odd P026 driver chip and lack of a shematic that stops me going further than Ebay.

Thanks again - Chris.
