Even a firmware update, won't change the possibility to change the resolution on the TV. Updates are only released for small bugs in the original software, Not because users want to do something different with the device. I think you will have to learn to live with the limitations of the TV. Or buy a large screen computer monitor.
Sorry I can't change this.
Fault with main board. Damaged component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

bad joint remove back panel with tv off check for any bad joints on power board also caused by thermal fault with tv on use a heat source over boards till tv shuts down then check suspect board
Now,u plug in the tv u get a solid red standby power red LED light in the front of the LCD panel right?When u push the power button on the remote u hear a clicking sound?Only one clicking sound,not the power supply board problems.It the Tuner board problems.But u can make sure it the power board problems or not.By taking the tv aparts check the power board,that board where the a/c power cord goes into it.Look all around the power supply board check for these leakage capacitors,they alway bulges up it top or puff up it top.No bad leakage capacitors,then it not the power supply board problems.
yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.
Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on
Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose
