Screen has turned a blue tint after turning itself off
My Toshiba 32A33 turned itself off and the red power light began flashing instead of remaining solid. I had to unplug the power cord and plug it back it to get it to turn back on. Now that it is back on, it looks like the picture has a translucent blue veil over it there are darker blue slanted lines across the screen. The TV is only 2 1/2 years old. Is this fixable for someone who has never repaired a TV before or do I need to call a specialist? Please help!

Re: Screen has turned a blue tint after turning itself...
I will not bore you with advice which you cannot follow. (90 % probability, looks like the Blue Signal Video Output Transistor has become faulty). This is a very simple "fixable' problem for a Professional Technician. Should not take more than 15-20 minutes.Nothing you can do. Call for Professional help.

Flashing lights on most TV's indicates a faulty voltage somewhere in the power supply or other voltage sensitive section. Like the "check engine" light on most cars, repair will require a trip to the shop. Get an estimate first. In the new world of disposable electronics the cost of repair may exceed the value of the set.
Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.
Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.
