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

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.

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.

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.

Sounds like a bad capacitor or two in the power section. Do you hear a hissing sound also?

Tv is on, after a few minutes it goes black and there is no sound. The indicator lamp is still green and stays solid the entire time. Without turning the TV off, in about a minute, you hear a small buzzing...


Someone else gave me the tip as I had the EXACT problem, but no buzzing. Unscrew the panel on the front bottom of the tv. Once that is off, there is another screw that opens a little panel. Unscrew the single screw with an allen wrench and pop out the bulb and casing. Mine was full of dust etc. Used an LCD cloth, but compressed air would do the same thing, put it back together and it works great!

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.

No picture, no sound?!?!


This could be a number of things. Your lamp could be bad or it needs to be reseated to the ballast. The lamp is trying to light and it will make the ballast flicker (that is the clicking sound) or your ballast is bad and it needs replaced (it will flicker and click too). Or your color wheel is broken and it will make a clicking sound when turning. If the color wheel is not spinning or broken it will not light the lamp. No lamp no picture.

No Signal through on my main TV input.


This may be the tuner or IF module that is failing. It may also be a voltage supply fault to these modules. It is impossible to accurately speculate without actualy troubleshooting the set.
