Model 32A40. Picture

No it is not a tube problem .............hit your TV on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width, or rolls etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears normally for some time............so solution is .....TV main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer & just ask him to resolder joints .............iam from bangalore - computers, laptop, printers, etc ) ----- good TV service engineer will charge less .........

Toshiba 32a40. The display on the screen shrinks

You've got at least one board that's gone bad. Were it mine, I'd donate it to a local charity and get a new one. The charities have volunteers and job trainees that do the repairs, and might be able to make a buck on it, while you get a tax write-off.

How come my 10-year-old toshiba tv now goes to screensaver in the middle of a program I'm watching

Hi, Please factory reset your toshiba tv or update your tv settings so that the screensaver is disabled. Either of these 2 actions should help you overcome this issue. If you don't see a screensaver option on your remote, please reference the table of contents within your manual. Thank you.

Toshiba 49L420U does not turn on

The 5 and 3.3 voltage is standby and that would be good if you get a standby light, you won't see the 16 volt unless the power supply is at full power or out of sleep mode. Look at the legend on the power board connector going to the main for something like PWR_ON, it may be marked different, but will have something about power on, you need to see just over 3 volts there when you push the power button, if 3 volts is there replace the power supply, if you don't see that go to the connector coming from the inferred board on the main board, measure the voltage at the pins, one will be 5 volts and one of the others need to change voltage when you push the power button on the remote, measure these one at a time, if none chance replace that board, if you see a change in voltage on one of the pins replace the main board.

Trouble with Toshiba flat screen

Over time with heating and cooling of the power board the fuse holder loses tension and won't make proper contact with the fuse, remove the fuse and bend the contacts together and see if it works, if it still gives trouble replace the power supply or solder the fuse to the holder if you have a soldering iron and can do the repairs.

Same problem, my Toshiba 26AV502R not powering on. I found the ceramic fuse blown on the power board & replaced it. The new fuse blew the instant I plugged the TV in. Any idea what is causing this?

Replace the power board if you can find one, unless you're an electrical engineer with the proper test gear high speed switching power supplies are to complex to service
