I was reading some of the others, and someone mentioned doing a reset by holding down a button while plugging it in.. how do you do that reset exactly? My TV won't do anything right now except blink that stupid power light.

Re: Aquos LC37D40U Blinking light and won't turn on
The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)
1x per second (constant steady blink) = bad inverters/lamps 2x per second = bad power supply 3x per second = bad main board
If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.
Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO
THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN
WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST
ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL
NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)
and hold at the same time “Vol –“ and “input” button on the TV set.
holding those buttons, plug the tv back in
should turn on by itself, keep holding the buttons until the letter “K”
appears. Then let go.
Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.
If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.

I read you must press 'Volume Up' and the XOOM 'power' button at the same time, hold until M logo appears, in effect triggering a 'soft reset'. This has worked 2 out of 3 times. The time it did not work I theorize I didn't hold the buttons down until the reboot screen appeared.
hi; please check the connectors of power supply board, and reset all connectors. if you have digital or analog tester,try to read the output voltage of the power supply http://www.youtube.com/ maybe no +5v going to mainboard.. or check the front panel board if its properly connected to mainboard. thanks....give some comment so i can help you more....
service menu procedure text changed by midge to work with Sharp LC-32P70E & probably the same for similar models.
There are probably ways of really messing up your set if you do the wrong thing from the service menus, so do this at your own risk:
To enter service menu, make sure the set is plugged in but turned off at the power button on the top of the tv, then while holding both input button and volume down button, push the power button. Within about 5 seconds, the set will power up keep holding the input and volume down buttons until a small "K" appears in a box on the left side of the screen. Then press and hold the channel down and vol down buttons at the same time to enter the service menu.
Once the service menu is displayed on the screen, you can get the screen to display different levels of solid grey by pressing the number keys on your remote. i.e. press "1" to get a relatively dark grey, 2 for a lighter grey, and so on up to 6 which is a bright white screen; 7, 8, and 9 don't appear to do anything. (this was for adjusting grey levels, other settings are available too) Press any number a second time to return to the service menu...
Not sure wether the grey background settings apply, but for entering the service menu it does.
I think to get out of service mode you have to disconnect the TV from the mains and wait about 30 seconds.
it's some time since I used the service menu on the Sharp Aquos but I do remember you can do a full reset to factory settings as well as turn on, off and reset certain system settings too you will just have to experiment with the remote keys, I think the colour fastext key access different menu levels etc but as I said I am unsure, at least this procedure will get you there so you can try for yourself.
Hope this helps
Please come back to let me know if the service menu procedure works for you.
- Unplug the TV and count to 10 slowly. - Hold down the power button on the TV (not the remote.) ;)))))) - Plug in the TV while holding power button. - Count to 10 and release the power button. - Turn it on and hope for the best
I know this is late, but this happens frequently. If anyone else has the same problem try unplugging the TV for 60 seconds. Plug it back in and then hold the power button down for 30 seconds.
That will reset the TV.
You should see the Westinghouse logo come up and the HDMI should work. This has happened twice with my TV in 1 year.
the problem is it is locked in store mode. I had to call panasonic to fix it, this is what they had me do.
1 hold the volume down on the tv while holding the menu button on the controller.
2 after the screen changes to the check menu, hold the off switch on the tv untill it turns off.
3 unplug the tv for 30 sec.
4 plug it back in and turn on the set.
5 select home option
6 your done.
Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.
You must unplug the unit, and while unplugged depress the volume up and channel down buttons at the same time (the buttons on the tv) and while buttons are depressed, plug the power cord in. Hold the buttons for 1 sec. then release. The unit should no be on in the service mode. A small k should appear on the screen. With the remote press the channel up button. There should now be a menu on the screen where you can see lamp error line. The lamp errors will most likely read 5 and 5 lamp errors in this unit will cause shut down. Use the channel down button on the remote until you highlight that line. Withe the curser right arrow button select the 5 and now with the channe up button you should be able to reset the 5 to a 0. Now unplug the unit and wait 30 sec. before powering the unit. That should return the unit to normal operation.
