Magnavox 42MF231D/37 will not completely power off, dim "backlight"

[Robb]

First off, thanks to the badcaps.net community, I would be lost and bored without you.

I just fixed a Y-buffer on this set. Everything seems normal except when I turn it off - by remote or tv's power button - it still has a very dim "backlight". I've read the service manual and searched around this forum and the web but haven't found this particular problem. Of coarse unplugging it solves the problem but I'm hoping for a more convenient solution. Anyone ever seen this issue before or know what might be causing this type of behavior?

Does this model have a digital TV tuner? Does it work properly? (DTV tuner can sometimes cause this issue.)

Yes this tv does. Worked on many of these sets and for some reason this happens to some. Its a firmware issue. Update if possible thru usb.

According to the service manual it has NTSC & ATSC. Digital STB is an option in the menu & under OSD Operation in the SM it says:
Channel turning
Available channels:
- Cable (analog NTSC or digital QAM)
- Terrestrial (analog NTSC or digital ATSC)

I don't really know. It accepts a signal from the cable box

Thanks freakaftr8 for confirming and tom66 for bringing it up. In the menu/settings I set all the inputs -except the HDMI- to "NONE" and it turned off after about 10 minutes of standby mode.

I downloaded 42mf231d_37_fus_eng.zip firmware and extracted it to a Fat32 usb drive using Linux but the TV didn't find the file in automatic update mode (turn TV on w/usb inserted) or in manual mode via the menu/settings. The Read Me says the usb format should be FAT/DOS so I think I just need to find another usb drive that doesn't have 10 LiveOSs on it as I'm too lazy to reinstall them.

Edit: 3.5 hours later it turned itself back on

After discovering there is no option on Linux with GPartEd or TestDisk to format partitions to FAT (only FAT12, FAT16, FAT32) I fired up a Windows box > opened Command Prompt > typed format e: /fs:FAT > copied Autorun.upg (downloaded from http://www.m4c.magnavox.com/cgi-bin/...scy=US&slg=ENG) to the USB drive> tried to install the firmware update and still it wouldn't find the update on the USB drive...not sure what I did wrong.

On a positive note, the TV only turned itself back on only once (mentioned in the edit above) and regularly powers off completely whether using the remote or the onboard power button.

Though perplexed I am happy it has no issues now. Thanks & Cheers
