The Mivar 14M3 is a TV for the Italian market made in the late 90's, basic yet almost bombproof in true Mivar style. It was later adapted to make the larger 16M1.
TDA8361
Controls
As indicated by the 9-key front panel without blue buttons, it has a minimal OSD limited to program & channel numbers and sleep timer (accessed by holding Stop): all adjustments have dedicated controls.
- Program/Channel/AV (remote and front panel)
- Volume (remote and front panel: latter also sets default)
- Tone/Mute (remote)
- Contrast (front panel)
- Brightness and saturation (remote)
- H position, V size, B+ voltage, Focus/Screen, G/B gain (internal)
Mods
- The back case can be drilled to allow external access to flyback controls.
- To reduce horizontal size to a moderate underscan, reduce by one step the retrace absorber C60 (2 kV, 6.8 → 5.6 nF).
- Disable standby: ground pin 17 of CPU
- Force AV: pull up pin 38 to 5 V via 1k resistor - or just remove the tuner
- NTSC upgrade: remove R102 (SMD, pulls up pin 34 of video processor TDA8361), replace with 18 pF and 3.58 MHz quartz to ground; connect variable 0-5 V source to its pin 27 for tint control.
- S-Video and YPbPr inputs seem to be theoretically possible but may be impractical to implement, research needed.
