Hello,

I am an electronics techo, dont work on TV`s that often but have had some
experience mainly friends family etc... have not worked on plasma screens so
im after some help/advice if possible.
The above unit has sound but picture died while watching it ( its not mine)
Unit is15 months old (warranty 12mths) , bought from Kmart apparently

Owner has been advised by phone (repairman has had an educated guess i
suppose)
that it probably is the microprocessor a new one would cost about $800,
would this include labour for fitting

Some questions
1. Would it be worth pursuing Sanyo??????


2. Can anyone provide me with a service manual and or schematic or details
of where to get one?


3. Have no reason to doubt repairman but $800 for a micro ?? would that be
right and while im at it
what microprocessor is it ( after a datasheet possibly)


4. Any other help/advice would be appreciated



thank you

Steve









Chances are the micro itself is a custom part and is not available to
ANYONE - including an authorized repair shop.
The usual repair process involves using the service manual - if you can
get it - to determine which circuit board has a fault and replacing the
entire board. Cost could be $400 to $1200 for the board depending on
which board it is. They don't make it easy or cost effective to do most
repairs.
