SOURCE: tv picture blinks off and on

The on and off conditions is repairable and is not the tube,you should have it check out for loose conections and try not to use it or it will go bad for good and the repair will become expensive,Check power supply,horizontal driver transformer and crt board,If you are not familiar with tv service be safe and call for help.

SOURCE: Sony Trinitron - Picture Disappears

Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

SOURCE: The picture went from clear to snow, but the sound remained clea

Could be the tuner or voltage going to the turner.

Any diagnostics events will be stored into NVM (non-volatile memory) and is useful for troubleshooting.

The diagnostics page can be accessed by pressing the following buttons on the remote control in sequence:

“DISPLAY’, “5”, “VOL-”, “POWER”.

The numbers on the left indicate how many times the timer LED flashed, which designates the probable cause of
the event.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.You can find it here: http://www.discount-merchant.com/Sony-XL-2200-TV-Bare-Lamp-Bulb-p/sony_xl-2200u_a1601753a_lamp.htm?Click=48173 Have a blessed one!

There is no picture coming up when I turn on ps-3. I have it connected by HDMI and I get the initial sound but not the final ding and there is no picture througout this process


First you need to turn the PS3 on by the switch on the PS3. Then press and hold the On/Off button on the PS3, keeping it pressed until you here a clear beep and then a couple of seconds after you should hear a second beep. Once you hear the second beep take your finger off the button. Now as long as you are on the correct HDMI channel the rest should be on the screen for you to complete.

Please Note - If you have it working on a particular TV, then decide to unplug the PS3 and put it on another TV, there is a very good chance it will be blank again. This is normal because each TV has different setting, pixels, size, etc, and the HDMI has to be set to each individual TV. Once you get use to the settings. It takes no more than 1 minute to do.

Hopefully this will solve your problem.

Ps3 reset


turn the PS3 off. hold the power button for at least 5 seconds or until you hear another beep.
This should reset all your ps3's settings.  If you have an HDMI connection, wait for a couple of seconds so that the PS3 recognizes and negotiates the right video output for your TV.
