Sharp Aquos 46" HDMI problem

Last night during a storm, while watching a blu-ray DVD on my Sharp Aqous blu-ray player hooked up to my Sharp Aquos 46" TV via one of the three HDMI ports, the power went off. It immediately came back on but when I turned the TV and DVD player back on, I got no signal. I hooked the HDMI cable to one of the other HDMI ports, all is fine. When I try to hook it back to the original port, still no signal. Did the power spike change some setting on that particular HDMI port? Can I reset it so I can use it in the future?

    Cable box is an older Knology HD DVR and only has composite output – no HDMI. I was able to switch the output from the DVD player to another HDMI input, in fact, I tried both of the other HDMI inputs, and it works on both of those two, so I don’t think it is the DVD player or cable. Funny thing is something similar happened some months ago and I since I have only one device with HDMI, I simply switched to another HDMI port and forgot about it. However, now that it happened again and I switched back to the HDMI port that I thought had died some months ago, and it works now, so, I was thinking it reset itself somehow and wondering if I can reset this HDMI port?

    I have a new Samsung Blue Ray and Samsung HD TV. At first I had an awful time w the HDMI Connection. I would have to wiggle the HDMI connector at both ends to get the TV to recognize a signal. You could be right about the setup. After I posted about the TV knowing which HDMI had a signal on it and would switch to it I wondered what would happen if ( you had a Cable box w HDMI) and a DVD player w HDMI and they were both on? Which signal would it use?? Maybe it starts at HDMI 1 and scans the other 2 until it finds an active signal. Or as you said you can preset it. Sorry I wasn't of any more help. My next stop would be Best Buy to ask about setup. Try a different cable before you go.

    This isn't comforting but you may have blown the output of the DVD Player or the input to the HDMI 1 on the TV. The whole thing behind ( 1 at least) is that it knows which input has a signal on it. So if you input on HDMI1 w a signal the TV will automatically switch to that input. Can you input from your cable box to HDMI1?? Or go from the output of the DVD Player to another TV HDMI Input??? Try different HDMI Cables ( I know they're expensive) but it will help eliminate the cable, TV or DVD.

I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?

Check its fuse at the power supply board. If found burned, make sure that there is shorted component/s. Try to repair it. If the repair cost exceed than the cost of a new one, replace it as card basis. It will be more better than try to repair these boards.
Contact the authorised service center for Sharp, to buy a new one.

Television is not recognizing HDMI inputs

there is a possibility that there might have been a power surge sent over hdmi into the hdmi board on the tv. if on your model the hdmi board is seperate from the sine board then youll have a cheap replacement if not its gonna cost you roughly 300-400 is my guess.

call your repair guy

Can not get my new 42 " Aquos TV to work with my new blue ray DVD

A blu ray player will play on any television. The television might not however have the highest resolution to display the full capability of a blue ray. That being said, the blu ray player may be faulty the connections may be incorrect. I would recommend running an HDMI cable from the A/V out on the blu ray to the HDMI input on the TV. GOod Luck

Aquos Turns off by itself

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

There isnt really anything you can do to fix it yourself, you can order the part over EBay, not hard to install just unscrew/unplug --- plug/screw..
