Have a Sony SMP N200. Was working great but suddenly one day nothing showes on tv screen. I tried unplugging all wires, exchanged them, swapped, tried hdmi and av but still nothing. Can anyone help?


Try doing the video reset. It seems to work the same for all SONY products. Hole the power down for a full cycle until it powers back off. I'm not sure if this will fix your issue, but it wont hurt to try. ^^ Good luck.

Sharp LC-32sb24u hdmi not working


You have to tell the TV which HDMI input to use. ie you should be able to press a button on your remote to do this. On my tv we can choose between 4 different HDMI inputs via the remote.

My ps3 console signal isn't working but the sound works but there is no signal! not even a hdmi cable works help!


Try these tips to fix the so-called "black screen of death".

Tip 1: The main reason of HDMI black screen problem due to HDMI cable may be damaged and not properly connected to the PS3 console. Please follow below step to troubleshoot PS3 HDMI cables problem:

1) Restart your PlayStation 3.
2) Look for loose cables.
3) Try to unplug all cables except the power cord, and plug them back in. If you found out that your HDMI cable is damaged, borrow a friends cable and try it. If your friends cable works fine, and the black screen error disappears. Then you can buy a brand new HDMI cable for a replacement.

Tip 2: Only try as last resort. There is a possibility you'll lose all data on your PS3's hard drive. If tip 1 didn't work, you will need to go a step deeper and reset your console. Most PS3 gamers are not aware that Sony actually included a black screen of death troubleshooting method and other HDMI problems in the PS3 manual, you can find it under the troubleshooting section - topic "console reset".

If you do it correctly, the console reset fix will allow you to reset back your PS3 to its default HDMI settings without impacting your gamer profile, and other storage data on the hard drive.

You will need to perform the following steps:

1. Place your PS3 in stand-by mode.
2. Hold down the touch power button until a series of beeps are heard.
3. Listen for one long beep, followed by two shorter beeps.
4. Release the power button.
5. Follow the instructions on screen.

If it works you should be good to go.

Blue no signal screen in the middle of playing a game - ps3 hdmi


Have your tried a different plug HDMI plug on your TV? Maybe bring your PS3 to a friend who has HDMI and try it on his TV. What about a diffferent HDMI cable?

Could also be your HDMI on your PS#, but try these other simple tasks first.

Good Luck

42" Sanyo HDTV with 3 HDMI Inputs


Everybody is having problems with sony products and HDMI cables. It's on a lot of forums. So, your not alone.
Most of the solutions are:
1. Unplug your TV for 30 mins.
2. Plug TV back in and put it on HDMI for PS3.
3. Hold down the power button for 10secs on the PS3
That should solve the problem.

Blue screen with HDMI


Check the power supply modular cable connection that is by itself in the upper right corner.  On the one my son-in-law has the double yellow jumper wire that connects to this plug in two locations was loose (not properly inserted) in the modular connector and had worked it way out.
