What does it mean when the picture goes blue? the picture turns blue while we watching it

The device sources and the inputs have not been set to the correct mod.There could be a problem with the TV it's self for it to be turning off like a problem with the power supply for the TV.

Hi, I also have that problem like yours. Is your watch already fixed? Can you please share. Thanks.

Try this repair video on youtube, might explain:

Here is what you need, its from the manual for your TV

symptom shows Blue CRT (picture tube) in your TV might defective and need to be replaced. Its high tech repair issue, so contact tv tech person if you don't have enough knowledge about tv repair.

post your model. Sounds like the blue CRT is shorted. But let me know the model and I will let you know how to test it.

Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

My panasonic Tv pic suddenly turned into a blue color I can't see the pic any more just can hear the audio.....any solutions????

That usually means the x-ray protect circuit was triggered. The set is going into protect shutdown for some reason. It may be a valid trigger to a lame problem or a fault in the detection circuit itself. I would hang a scope on there and just watch to see if there is a strange movement in voltage values, and if so, troubleshoot it from there. The blue picture is a result of a convergence problem. If you don't know much abou TV repair, I would suggest taking it to a Toshiba authorized servicer for proper diagnosis.
