We would like to notify Doctor V64 owners
not to downgrade their Doctor V64 Flash ROM to older versions of BIOS. Downgrading back to
old BIOS might cause a corruption to the Flash ROM and thus making the Doctor V64
inoperable or unable to upgrade back to newer versions. We suggest users with this problem
not to return their Doctor V64 to us but does the following.
1. If your BIOS is not able to upgrade
but there is screen on the TV, burn a CD-R with only the new BIOS in it and load into the
Doctor V64. For BIOS 1.52 and before, hold the 'CH' button before pressing the 'Play'
button and follow the instruction on the screen. For BIOS 1.53 and after, just load the
new BIOS file and follow the instructions on screen. If BIOS has been downgraded to
version below 1.70, use 'tpc.exe' and not 'tpc2.exe' to communicate with Doctor V64. Some
computers will not be able to communicate with 'tpc.exe' and BIOS version below 1.70.
Therefore, users have to use CD to upgrade.
2. If there is no image on the screen
after an older version of BIOS has been downloaded to the Flash ROM, the Flash ROM is
corrupted. We suggest user not to return the Doctor V64 as the shipment cost will be more
expensive then just buying a Flash ROM from us. We charge US$10 for a Flash ROM and the
price includes shipping worldwide. Replacing the Flash ROM only applies to user who has
blank screen due to a corrupted Flash ROM after they have upgraded or downgraded the BIOS.
If the Doctor V64 is not showing any image and user has not upgraded or downgraded their
BIOS, it is due to other reasons.
We stronger suggest users not to
downgrade their BIOS to older versions as many users have problems after.
If you want to purchase a FlashROM from
us to replace your corrupted FlashROM, please fill up our repair order form.
