SECTION 8
Troubleshooting the PTV16C
Problem:
Cannot Tune my TV to the PTV16C - No Picture - only Static on the screen.
Check The following items:
• PTV16C 9V battery - Ensure you have a fresh Duracell Brand 9V Alkalline battery
• PTV16C On Switch - Its obvious, but hey, gotta check - LED Glows RED
• PTV16C Bent or damaged - have the PC boards been banged hard or bent?
• TV Set - Review Section 2 - You MUST be tuned to UHF channel 16 and have a UHF
antenna installed on the TV set and the TV must be set to receive airborne UHF TV
signals. If you are truly frustrated at your TV set, try another TV in your house which
may be less cryptic. For Best Results, use a manually tunable TV Receiver with fine
tuning - Handheld TV sets (for example CASIO Model EV660) with digital scan tuning
are ideal for continuous PTV16C UHF Channel 16 reception. If all else fails, take your
antenna with you and head to your friends TV set and have him or her set it up for you.
Problem:
My PTV16C was working fine until I squished the PC boards accidentally when it was in
my pocket during a rugby game.
Check the following items:
• PTV16C on/off switch - maybe you are lucky and this is the only problem.
• Inductor Coil - If you squished or squeezed the inductor coil, there is a good chance
that you have fouled the tuning of the transmitter circuit. The coil is fairly robust, and is
held in firmly in position, but remember, this kit weighs only 16 grams, you will have to
be gentle with it. It is quite possible to alter the tuning with rough play. If you have total-
ly screwed up the tuning you may have to retune it with a spectrum analyser, or send it
back to Plantraco for servicing and retuning.
Problem:
My PTV16C has some weird distortion in the broadcasted picture.
• Some amount of distortion is to be expected and is within the normal window of operation
of this device. There are many things in your setup that you can do to maximize
performance of the PTV16C. “Multi-Path” signal reception occurs when operating the
PTV16C in an area with metal obstacles - the “Multi-Path” signals ricochet off of objects
and are received at slightly different times and are displayed on the TV screen as a
ghosting or other picture abberation.
• Its a good idea to set up your PTV16C in ideal conditions so that you can begin to learn
what is causing the disruption in your signal so that you can compensate for it. A little
bit of experimentation can go a long way towards increasing your picture quality.
