Repost, of a problem!!
is this any help?
Toshiba TV Various Models Service mode procedure for most Toshiba TVs Press sound mute (on remote)- Tv displays sound mute OSD, Then hold down sound mute and press the menu button on the control panel This should display the service mode data with an 'S' in the corner of the screen. Gives basic geometry and display data. Press the -- button on the remote - enters frame collapse mode - to set screen voltage When in service mode:- Hold down CALL (on the remote) and press the menu button, Set then enters design mode All sub data can then be adjusted. Projection models From service mode - pressing the yellow button on the remote gives the convergence adjustment mode Up/2 Down/8 Left/4 Right/6 Press 5 to toggle adjustment / move - on / off Press 3 to change colour to be adjusted It is recommended that the green convergence grid should not be adjusted Pressing the red green or blue buttons will toggle the corresponding convergence grid From service mode - hold down the F on the remote and press 7 - enters convergence menu - auto convergence setup for different aspect ratios Rono wrote: Some of you guys misunderstand what I want! How do I get into the EEPROM, & Micro, in order to change the parameters! Example: The vertical height is too high! Got a Toshiba M # 24AF43, Chassis # M3M627. Plug it in, barely visible out of horizontal sync video, (basically, no video), no sound, change channels, & you can see that the channel has changed! Looks like a "Prima" T.V. problem, almost exactly the same! All measures good on the board...looks like EEPROM/ Micro problem! Called Toshiba, & they were just closing for the year!! How do I get into, & change the EEPROM, & micro values! Thanks, Rono |

Thanks, Rono I have a Toshiba 2577DB with a geometry problem; I can enter service mode as 'Big Tom' described, but I don't know what the OSD abbreviations mean. I tried downloading a manual but I cannot open the 'rar' archive that it's stored in. Can anyone tell me what the OSD messages in service mode mean?
