Alright well I'm sparking up the Kuro thread after a while so bear with me please. My PRO-151FD has a red tint, like many of your panels, and after seeing it, I cant UN-see it, so here I am, with 30 different tabs open on how to repair the problem. The main issue, however, is not even being able to access the service menu in the first place. I've bought the TREND-net and Startech cables linked at the beginning of multiple threads, and also another completely separate brand, yet no matter what command I send the Kuro, it refuses to respond. I've done a loopback test, so I know the cables are all good (they are all straight cables), I've ensured the baud rate is 9600 on both the Kuro and the PC (and tried others on both ends, including 1200 and 38400), the stop bits are 1, data bits are 8, parity and flow control are set to none as well. There is only one COM port to connect to, so that is the adapter's. I've also tried multiple programs, including Hyperterminal, Putty, Kuro Control, and Kuro Command. Kuro Tables and KuroKal both freeze up when I click connect, KuroControl give timeout errors, Kuro Kapture gives a blank document when setting it to auto, and Kuro Command, Putty, and Hyper Terminal send commands without any response from the Kuro. I've rebooted, reinstalled drivers, tried an XP machine, and I've literally given up. Does anyone here have any ideas for what I can try to get this dang panel into service mode?
If Kuro Tables and KuroCal crashed then you are either selecting the wrong COM port or, a long shot, but I've had this happen before, the TV's serial port is not working. You can remedy this by replacing the main board.
Another possibility for KuroCal and KuroTables locking up is that they both send a couple of commands to the TV right after you click Connect. I suggest using Kuro Command and entering the correct COM port. Issue the qaj command to display the current voltages.
I'm assuming you purchased the adapter and cable from the links that I posted in the first post of my programs threads?
I'd also like to assume that the TV is ON when you are attempting to connect? You are connecting the cable to the TV's serial port and NOT the VGA port right?
Keep in mind that there's really not much you can do regarding red tint on 60 inch Kuros, as they don't offer the same level of tweaking wiggle room to have a noticeable impact on red tint. If the red tint is unbearable, I suggest you relegate the 151fd to daytime viewing and purchase a different set for night time viewing. I sold my red tinted 141fd and replaced it with a 70 inch Sharp Elite and don't regret it one bit. In fact, it's my favorite 1080p set! Yes even over Kuro!
