Question about Toshiba Televison & Video

1 Answer

Toshiba 49L3750VT half screen bright, other half dull.

This vertical split is a perfect 50/50, the "dull" half is a softer tone than the bright half. Nothing in the manual to help. I have tried changing the "Location" setting between "Store" and "Home" but this makes no difference (I was thinking Demo-mode). It does this on all inputs. Any ideas? Can I upload or embed a photo here?

First you have to check if voltage and data are ok at the Y sustain board and the Y driver boards are not running hot. Even if you know how to replace these panels you must have a scope to adjust the v-set up and v- down. Not just a simple PNP. Trouble shooting a plasma is not a short time process to do it correctly. Please let a service center look at it for you.

Dull picture on laptop but cursor is still bright


The screen brightness is automatically adjusted by your laptop's Power Management configuration in the Control Panel. Depending on your laptop's brand you might not only have the Windows power management, but also a proprietary power management application within the control panel or in your Start Menu programs usually listed under your computer's brand name. For example a program folder called "Toshiba" under Programs for a Toshiba laptop. Anyway, I would start there. Usually you can set up the screen brightness according to whether or your computer is plugged in or working on battery. Good luck! :)
