DA100 (50Hz) Chassis – Article for Television Magazine 

Sharp Electronics (UK) Limited - March 2003 

Note that the HW blanking jig works at the lower supply voltage of 3.3V.  Although it will not be 
damaged when fitted to a set with a 5V supply, the NVM will not be blanked if it is used.  The reverse 
is also the case – FW jig used with a 3.3V supply. 
 
Using the jig is simple, just follow the instructions below: 
 
1.  Turn the television off at the mains 
2.  Remove IC1002 
3.  Replace IC1002 with the correct blanking jig 
4.  For sets with two NVM’s, disconnect pin 5 of IC1004 
5.  Turn the set on (out of stand by) 
6.  Wait for one minute 
7.  Turn set off at the mains 
8.  Remove the blanking jig from IC1002 socket 
9.  Replace original IC1002 
10.  Turn set on on (out of stand by) 
11.  Set will take about a minute to come on 

To make fault finding a lot easier, Sharp have issued details of a handy little jig that enables these 
little IC’s to be programmed quickly and easily.  In most cases the NVM does not have to be removed 
from the PWB.  Using default data available on the Sharp Technical web site (for account holders only) 
or for non Sharp account holders, on a disk available from Sharp parts centre, payment by credit card.  
Alternatively the kit can be purchased from Willow Vale Electronics.   

 

  
Once the jig has been made, and the software installed onto a PC it is possible to program the NVM, 
view the data and even take data out of a good NVM.   Version 1.17 of the Ponyprog software is 
recommended for use with this jig, as other versions have been know to cause various communication 
failures and therefore crashed data. 
Note that more details of this jig were given in the February 2003 issue of Television magazine.
