My classroom TV seems to be stuck in standby mode. Blue light is on but TV won't turn on either by push button or remote.

SOURCE: need remote control codes for a Olevia 323-s11 tv

Try code - 11331

Can also depend on which direct tv remote you have. The manuals for most of them are listed here:

On the remote, hit the "Menu" button and then press the down arrow until you see "Picture," then hit enter, now hit the down arrow until you see "mode" and hit enter again. You should then see "power up" displayed. Hit enter again to get to the setting choices where you can change the mode back to "home" (hitting enter one more time) then exit the set-up menu.

Most likely the CCFL inverter has been the problem all along....
