How do I retune a Toshiba Regza 32AV615DB 32-inch when I select retore defaults nothing happens

To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

why supply 13volt is not out,but 5v is working

On the back of the TV, where the main board is (the one with many AV inputs to it) there are several cables going into it.

Find the one that leads to the buttons on the TV - it won't be too hard to trace - and after turning on the TV disconnect that cable.

Or, if the cables for the buttons and the front LED and IR sensor are separate (sometimes they are) you disconnect the one for the buttons and then turn the TV on with the remote.

Either way, see if the problem persists with the buttons panel disconnected.

if it does then the problem is in the main board and likely you'll want it replaced. The way they make them these days it's really cheaper to replace the whole thing than to look for a problem among components the largest of which is about a millimeter long.

if the problem is in the button/cable connector...you'll probably find it easy. Often it's because that same cable has been trapped between the front and back covers and broken or shorted by the friction and pressure.

Hope this helps....would appreciate a review on Google if it does!

There is a input selection switching IC at the input section circuit. It t damaged. Seek experienced service tech: assistance.

where can I get a replacment stand for a toshiba W42LT66

Try resetting to the factory default and then retuning the set. See if you can solve it that way.

Mine isn't exactly the same model (I've a Toshiba Regza 32AV615DB) but on mine there are 4 small black screws at the back of the TV, near the lower edge. They're recessed into channels and quite difficult to see. Remove these 4 screws and you can lift the TV off the stand. Good luck.

Make sure set on air,not cable in menu setting,Get a digital antena or a rooof antena.Hook up u should get the DTV free signal.

Does it work with a DVD or VCR?
How is it connected? With a Coax cable or a an RCA component cable? Check that the correct video source is selected (The one associated with the input you are connected with) or that you are tuned to the correct channel on the TV if you are using the coaxial cable to connect. Could be channel 3 or 4 but I have seen them set for channels like 73.
