Sharp Aquos not always starting up immediately when powering on??
I own a Sharp LC-52SE94U, sometimes when turning on my TV, I have to wait for the TV to fire up. I hear the relay click 1, 2 or 3 times and then nothing. Sometimes it fires up right away, no problem at all and then sometimes it starts right after the first click or sometimes after the 3rd. Usually when it reaches the 3rd click the Front lights located on the TV for the POWER and the OPC lights blink. Then I have to power off and power on the TV again and it could start right up.
I am not sure if this is a conflict between hardware (since hardware firing up sometimes appears to help assist the TV in firing up) or dirty power, since my building is not exactly the newest. Other than this issue the TV works great.
My other hardware is a Samsung HTTX75 HTIB, Sony PS3 and Motorola PVR 3416, not sure if the conflict lies in there somewhere.
Any help would be appreciated.
Also I contacted Sharp and they sent out a repairman and of course the TV started up fine while he was here. So he reset the display and it seemed fine for awhile. This issue is hit or miss, but dam annoying, sometimes it will not happen for a week or 2 weeks, then 5 times in a row.
Re: Sharp Aquos not always starting up immediately when...
I had the same exact thing happen. I think it's related to a failed firmware update attempt after reading a post on the AVS forum of a guy who also had this problem on this TV. What I did is plug back in the USB drive with the firmware update on it that I had used earlier, and the TV started right up.

DISH Network blocks multiple video outputs on all PPV and most premium content to prevent recording, and they will tell you it is a TV issue. Ensure that your receiver only has one video cable coming out, to only one device (ie HDMI to the TV) and try again.
There is a software update for this model via the Sharp website. Included is a link to the compressed folder. Once you uncompressed the folder there are instructions in the folder on how to install the update. It doesn't specifically say this is a fix but as a TV technician personally its the fist thing I would try.

Aquos has the same problem. I'm not sure how I discovered this, but
when I lean the TV forward and hit the power button it will turn on
every time. If the screen blacks out and I don't lean it forward when I
hit the power button, the screen will just remain blank. It is very
weird, but at least repeatable.
- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.
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.
