Hi,

I got the chat , but some how it got disconnected.
But i would like to help you in this aspect.
HDMI stands for High Definition Multimedia Interface, and supports transmission of both audio and video in high fidelity.

First make sure these things,

Both your computer and your TV will need to support HDMI interface.
It's quite a recent thing in PC graphics cards, so you may have to resort to S-Video, DVI or VGA for the video, plus a 3.5mm stereo cable (or the optical TOSLINK equivalent) for the sound.

Let know your comments and i will follow up with the suggestions.
Thanx for using fixya,
Good luck.

SOURCE: Sharp Aquos LC-32B20E wont display a PS3 output via HDMI

kitconnolly,

I too went through this problem.

Step 1 - Plug in your "composite" cables and the HDMI cable to the PS3. Obviously, the "composite" cable are the ones that came with the system. You need to start with them as the default connector.

Step 2 - After connecting the "composite" cable and the HDMI cable to the PS3, connect the other ends to your TV.

Step 3 - Power on your PS3

Step 4 - Select display settings-->video output settings

Step 5 - Change from the current video cables to HDMI. (Your tv has different inputs. When you switch to HDMI in the PS3, you will have to switch your TV to the HDMI input that it is connected to, to get a picture)

Step 6 - Be quick, the PS3 will display a "test" for 30 seconds. You need to switch your tv to the correct HDMI input and press "X" on your controller to accept the change.

Let me know how this works for you.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: Problem connecting my PS3 to my Sharp Aquos LC-C3237U LCD TV

Your PS3 set itself above the max resolution your LC-C3237U. Most likely the PS3 is doing 1080P, but the highest the Sharp can do is 1080i. So do this:

1. Connect PS3 to TV (you can use the current cable or analog cable)
2. Turn on TV and set input to port PS3 is on.
3. Make sure PS3 is connected via correct cable.
4. Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.

Will my smart tv get wifi


The Sharp LC-55LE643 does not have Wi-fi built in. However, it shipped with a Roku Stick which does use your wireless network. Thus it is considered a Wifi-ready TV. The detailed specifications for the LC-55LE643 are available from the Sharp support site: http://www.sharpusa.com/Support/ProductDetail.aspx?model=LC-55LE643U . The direct link to the specifications sheet is currently http://www.sharpusa.com/~/media/75A4516B13A842F6BEB7C52161E46A59.ashx .

I hope this helps.

My sharp aquos LC-60E79U has no picture. Perhaps I have a backlight problem?


. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The TV sensor no longer picks up the remote signal.


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.

Sharp tv has no power


Sounds like your set has been zapped by a spike on the line. Now you know why UPS units and surge diverters were invented.
A new TV sounds probable as many components could be damaged. If you are lucky it could be just a fuse but I have my doubts.
Moral, invest in a surge diverter, it would have saved you a new TV

Is it normal to take about 18 seconds to start


If you notice the time taken to start is more than what it was before, slowly the power supply board is developing problems, due to leaky or dry capacitors or dry solder.

No Picture with sound


sounds like you have a bad panel. This ussually happens when a backlight lamp has gone bad and the inverter board senses this and sends a signal to turn the backlight off.
