Hi all. I am having audio issues with my Hitachi 42HDT52 Plasma TV – about 50%-60% of the time, there is no sound on the HDMI ports when initially turned on. I can get sound if, using the remote, I switch to another input source and then back to the HDMI source. I know that it's an old TV but among the much newer ones in my house, it is still the best picture of any of them.
I am unable to find a Hitachi web site with any support files, firmware, manuals, etc. but after contacting Hitachi Customer Service by email, I got the following reply:
================================================
"Hello Howard Woodard and thank you for contacting Hitachi,
Please see firmware update .zip file and instructions on how to proceed attached below. Keep in mind that the firmware needs to be placed on an SD card no greater than 1Gb in size, otherwise the TV may not recognize the storage device.
Thank you for choosing Hitachi,"
================================================
I unzipped the file that was included, and it contained a 12MB file, DW1UA116.E01, along with the update instructions. I had already discovered that the TV did not accept 9-pin SD cards and required the older 7-pin MMC cards that are 1GB or less, so I bought one on eBay that was 256MB.
The TV still gives no indication that it is finding the update -- I don't know if it's not finding the card or if it's finding the card but not recognizing the fw update file. I found one post where the person was successful back when the TV was newer, and Hitachi kept its support files online. However, it was an old post, did not contain any specifics about the file name, and the OP never responded to any of my inquiries.
Does anyone have any information/experience with this issue that could offer me some guidance? I'd sure appreciate it if so.
