Sylvania LC427SSX FIRMWARE - Anyone Have it?

[Neonpeon]

After a call to Sylvania today, it is apparent that I am not going to be able to get any firmware from them. According to 2 customer support people, and a manager, they no longer have access to firmware for their tvs.

I am having a problem with the Audio not coming back up after restarting the tv on the HDMI ports. Seems there is an update 1.6 that is supposed to fix this.

This is same chassis as the Magnavox 42MF438B/F7, I am wondering if I can flash it with this firmware.

I seem to keep answering my own questions here lately
Anyway. The Magnavox firmware DOES work. It only needs to be renamed.

Magnavox file: M42OS_107_AB.ecc
Sylvania file: L42OS_107_AB.ecc

Software History
Version 1.4 Audio missing on some analog cable channels.
Version 1.5 No picture when some DVD players are connected using HDMI.
Version 1.6 Missing audio or video when switching from one HDMI input to
another.

I have included the firmware file here.
Maybe this will help someone.

Hi
Great work!

How did you do the update? USB, Programmer

USB. Copy the firmware file to a FAT32 formatted Flash Drive. Turn off the tv before inserting the flash drive. Turn on the TV and it should pop up with a message to update the firmware on the screen.

One note: Although this worked great for my Sylvania TV, when I go into the menus, it shows Maganvox. Not a biggie for me, but it may not be great for a customers TV.

This DID fix my audio problem.

I know I'm a bit late to this forum, but can anyone else like Neonpeon confirm that the remote stops working after the update of the firmware?

I know it's long since past this being posted. But just for anyone who comes across this as I did. I can confirm that this does in fact causes the oem remote to no longer work. I would also like to add though, if you attempt to use a universal remote you must connect to it as a Magnavox. But it works great.
