I can vouch for what is said here.
I have problems with my Prism too
last time my Netflix will suddenly show static, then crash.
whats annoying is, the tv silent auto reboots. you wont know it unless you can see the standby light going off. after a few mins, it will turn off by itself and the standby light will come on again.
what was weird is, one time i saw it being left on for a whole 10 mins, yup, I counted the time.
silent reboot -> the tv is on, but the screen is off. if you press the power button on the remote, the tv picture (ch5/CNA) instantly comes on without showing the Prism+ logo. this confirms that the TV is turned on.
if you have plugged your tv using ARC to some speaker or sound system, it will also turn on due to the TV's auto reboot.
you know what's funny? the auto reboot happens every 8 hours on the dot. ie, 3 times a day. sometimes the timing gets disrupted or reset and changes to another timing if i do a factory reset or turn off the main switch etc....
I have seen someone commenting on these issues and I also replied on the customer's comment. after a few days, that comment got deleted.
Im on the verge of asking for a refund. but i dont know what TV to get
their replies to my emails have been prompt and they reply me well, with good info and options given. yes their QC is lacking, but their customer support (thru email) is splendid for me so far.
