Down to 1 TROUBLESHOOTING
The Down to 1 strategy is to have set troubleshooting methods that will best ensure an accurate diagnosis
as quickly as possible. The following troubleshooting methods will help the service technician gain the
Down to 1 advantage.
USER LEVEL RESETS AND INITIALIZATION
As in previous models, many symptoms (customer generated or intermittent) may be resolved by per-
forming a reset or initialization. Many of these functions are available to the customer. Asking the user
to perform these resets may eliminate the need for a service call. If the exact nature of a symptom is un-
known, it’s best to have the customer perform the procedures in a specific order to minimize the number
of settings that will be affected. The procedures, order and method are:
1. System Reset - Press and hold the <POWER> button for 8 seconds. Or remove and re-apply
power.
2. A/V Reset by Input - Select the Input to be reset. Press remote <MENU> Select “Audio/Video”
Select “AV Reset “ <ENTER>
3. A/V Reset all Inputs - Press side panel <INPUT> and <VOL > buttons at the same time and
hold for 10 seconds.
4. Initialize (User Level) - Press remote <MENU><1-2-3><ENTER>.
If a user level reset does not correct the problem, it may be necessary to perform a Service Level Initiali-
zation from the Option Menu as part of a service call.
PICTURE PERFORMANCE COMPLAINTS
Like many Mitsubishi models, the V46 chassis has a “Test Picture” that can be accessed from the cus-
tomer menu. Press <MENU> select “Global” then “Test Picture.” A photograph of the “Lady” will be
displayed. If a TV picture performance problem exists, it should be evident. Otherwise, the test picture
will have demonstrated that the set is capable of a quality display and the problem is likely due to a sig-
nal source or other external cause.
