8.16 TV TROUBLESHOOTING - PICTURE FUZZY OR UNCLEAR

1) For a fuzzy or unclear picture, see the TV programming instructions in Section 10. If the TV is still fuzzy or unclear after programming:

a) Check the coax connection at the entertainment port (Figure A).

b) Remove the 5 screws holding the console to the console mast and check the coax connection at the console (Figure B).

c) Use a verified good piece of coax cable (a good coax cable will have a signal strength of 10 db or greater) to plug directly into the back

of the console bypassing the entertainment port. If this resolves the issue, replace the internal coax cable.

d) If plugging the coax cable into the back of the console does not resolve the issue, remove the console back and check the console

cable connection at the tuner (Figure C).

e) Check the internal cables and fitting inside your machine at the console and below the front shroud (Figure D). Make sure you have

no kinks, cuts, or poor connectors at the end of the cable. Fittings should have a clean flush connector with no stray aluminum strands touching

the center conductor. Replace any suspect cables.

f) If no damage can be found on the cables, fittings, or connectors, and hooking the coax directly to the back of the console does not

resolve the issue, replace the TV tuner.
