RCA ColorTrak Plus-27"-No

RCA ColorTrak Plus-27"-No channels below 51' I woke up from a nap yesterday and found that I could no longer get channel "line in thru 50". When I went into the set up menue I tried auto and manule programing, they all seem to be "enabled". It seems like it must be a hard ware problem to me. Anyone have any suggestions. Thanks Martian

Not sure if this process

Not sure if this process applies to the same model. but here is a little something i found . This applies to model P56830BL, but may work with similar models that were manufactured around the the same time or with in a couple years appart...

Service Mode
Most of the alignments for this chassis are software-driven;
adjustments are made by modifying parameter values using
Chipper Check and the service menu. When parameter values
are modified, the corresponding T-chip registers, tuner
registers and EEprom locations are updated.
A list of the software alignment parameters accessable
using the front panel is shown in Table 1. The remainder of the
alignments require Chipper Check®.
Page 3-2
Entering the Service Mode Using the Front Panel Controls
1. Press and release the POWER button to turn the
instrument on.
2. Press and hold the MENU button.
a. Press and release the POWER button.
b. Press and release the VOL+ button.
3. Release the MENU button.
The instrument will display the following menu:
The CH Ù and CH Ú buttons on the front panel (or the
remote transmitter) are used to change the parameter (P)
number. The VOL + and VOL - buttons are used to change the
parameter value (V).
NOTE: Attempting to change the parameter number (using
CH Ù or CH Ú) at this point will cause the instrument
to exit the service mode. A valid security code must
be entered (using VOL + or VOL -) before selecting
an alignment parameter.
Security Codes
When the service mode is first turned on, the parameter will
be "0", which does not correspond to an alignment. This is the
security code parameter, the purpose of which is to prevent
accidental entry into the parameter groups. The value (V)
must be set to 76 for Front panel access to chassis
alignments. The value (V) must be set to 80 for Front panel
(remote control) convergence adjustments or to 200 for
Chipper Check®. Once Chipper Check® mode (V=200) is
selected, the Chipper Check® interface box will take control of
the instrument and the front panel will become inoperative.
Once a security code has been set, pressing CH Ù or CH Ú
will result in the following display:
Where: YY = parameter number
ZZZ = current value
At this point, the CH Ù and CH Ú buttons can be used to
change the parameter number and the VOL + and VOL -
buttons can be used to change the value of the parameter
selected.

Note: be very careful in what values are changed, also before changing any values it might be a good idea to wright them down so that you can refer to them if need be..

Hope this helps someone..

Your eeprom and or the tuner

Your eeprom and or the tuner is probably bad. Changing values in the menu will not fix your problem I'm afraid and could damage the set even more. Good Luck.
