Question about Toshiba Televison & Video
I've been using Toshiba 40RL938 for 4 months. But the volume goes up and after some seconds returns back to its previous volume. What can be the reason for this problem?
There is fault in its main digital processor board. As set is new, and will be in warranty period, it will be best not to do any repair to it by yourself, as warranty will expire. Contact the authorized service center or dealer immedietely.

That could be a cold solder of components or a connectors problem go ahead and open the back cover of your TV.Re seat all the ribbon connectors from the mainboard make sure it properly fits the terminal.
Re solder the power supply board use a soldering iron.the power supply board is where the power cord is connected.also re solder the terminal of the connectors going to the backlight of the TV.this connectors often looses it solder because of the high current going to the inverter board.resolder also the inverter board..good luck!
