Tv firmware updates - Hisense LCD1504 15 in. Television

Question edited for a lot more clarity! All questions need full 'make model (what it is)' please.
Question moved to Sharp Aquos category.

This is their support page which is pretty bad. There is an email link. You don't say WHY you want a firmware update, but firmware in not supplied for televisions according to our Fixya television expert Larry. Firmware updating is fraught with danger and should not be undertaken lightly even when it is available. Sharp only supply software updates, no firmware.

SOFTWARE updates are here in the manual on this page and continues in detail on the next page.

You should only do Firmware updates when absolutely necessary. Software updates are not a problem. Firmware dictates what happens before the software loads.

Contact Wansa and ask them for a new set or a new mainboard. If it is a software update that went wrong, there is help here. Firmware and software are not the same and the words are interchangeable.

Eventually the updates stop as the hardware becomes dated to any new software version. The idea is that you update the television.

If there are no downloads available for your TV model, either your won't be able to click the tab or there will be a message within the tab that says there are no downloads at this time. If this is the case, no firmware updates are available for your Toshiba TV. Check back periodically, as firmware updates are released as needed and aren't scheduled.
10. If there is content in the Downloads section, look in the Category section for an item titled TV Firmware. If this option doesn't appear, no firmware update is available.

Emerson does not list any firmware updates are available for the LC501EM3.

Either check around in Any DVD HD or the BluRay menu to set audio output to PCM, which doesn't require any decoding to play back properly or you will have to convert them separately.
