Default service menu codes

I would check the menu settings and reset everything to default. if there are calibration tests in the menu, use them. Try more than one source for video.

1. To enter the Service Alignment Mode (SAM), press the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status.

2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Geometry sub menu.

3. Use the Menu Left/Right keys to enter the Geometry sub menu.
4. In the Geometry sub-menu, use the Menu Up/Down buttons to select VAM.
5. Using the Menu Left/Right keys, adjust VSH so that the horizontal bar is properly centered, top to bottom.

6. Using the cursor up/down keys, select VAM from the Geometry sub-menu, and use the Menu Right key to

increase the value to obtain a slight overscan.

7. If other Geometry adjustments are needed, proceed to the necessary adjustment using the Menu Up/Down

buttons.
8. Upon completion of Geometry adjustments, press the Menu button to return to the top level SAM menu.
9. To exit the Service Alignment Mode, turn the set off with the Power button on the remote control.

try the 'default' setting of the tv.

If you have the model listed have fun----Geometry values are depicted in the Convergence section---the grid of GREEN lines determines geometry and red and blue are then adjusted to the Green.

Primitive: Set had at one time two overlays available--clear plastic you attached to screen to line the that Green grid up against---one for 480 and one for 1080.

Once the geometry is set (best possible) you must align convergence and save it in both the modes one at a time.

By current standards a Fred Flintstone system--but in its day a real pain as alignment can take many hours with the correct remote via the tech menu for convergence.

This set is full of safety circuits that can cause this. It is really hard to say because anything can cause that. Have a shop check it out for you. Thanks for using fixya.

Service Menu Access Procedure To access the service menu, press and hold the handset sound mute button whilst pressing the TV's front panel 'Menu' button (under the front panel cover on the TV). The up/down channel buttons on the handset step through the options and the left/right buttons change the data values. Turn the TV off to get out of service mode and DO NOT touch any other handset buttons whilst in service mode. Service menu access is also similar for many other Toshiba large-screen TV's so this procedure may work on other Toshiba TV's - even those sold outside the UK.

Maybe this list can help you, click here for a list of each widescreen Toshiba TV Service Menu adjustment with details on the purpose of each.

The factory settings of each service menu option will be entirely different on every TV manufactured, due to component, tube and scan coil tolerances, so don't under any circumstances adjust your TV's settings to my factory default settings or your TV's picture will probably look awful! The factory settings are provided out of interest - the useful part of this document is actually the definition of each service menu option. You will see that some geometry settings are duplicated for each screen mode such as 'Cinema' and 'Subtitle'. This could, for example, help resolve a geometry problem that's present just in one screen mode.

I hope help you with this.

It is my guess that you have some pcb circuit traces that are cracked. Maybe near the back of the set near the input jacks.

Geometry adjustments are done in the servicer menu by
skilled technicians only.Adjustment service calls can cost
around 150.00.......T.

If you are doing the labor you should wait and replace the new part and while you are at it check for loose conections in the horizontal drive circuit since all symptoms might be related,but they are doing all the work they should address all the problems you have,settings in the service menu dont just change on their own and are adjusted only when a major comp[onent has been change like the convergence.
