I bought a used #9P6034C102 60in Phillips Magnavox and it was working fine and then all of a sudden the TV had a huge white blob with some rainbow colors around it, you could still hear the sound but could not see anything. I turned it off and then tried to turn it back on and now its a black screen with no sound, Thanks for any help!

we just bought a 55 inch phillips magnavox and told it was working fine when we got it home and turned it on it was a red screen and was really foggy. we looked up some tv repair places and ONLY 1 told us it was the picture tube and to look down them with a flashlight for bacteria! sure enough the green and blue had it. so we found one place that would sell us the coolant fluid that you have to change the others could get it in or wanted us to bring the tv to them. we did it our selves the stuff was $17.00 a bottle or if we took it in it would be about $375.00. we have a great picture now and it wasn't as hard as all the other repair places said.
I had a similar problem with my magnavox tv with the blinking light issue. Eventually it just didn't come one anymore. Looking at other forms they said the problem was a bad capacitor number 2074 located on the power supply board. When I opened my tv, I noticed that the capacitor was bulging and burnt up. I bought a new one labeled 2200uf 35v and did some solder to attach the new piece. Put the tv back together and it works like new. No more blinking light. I hope this helps.
It sounds like the 3 "GUNS" are not aligned.
One the controls at the bottom, left hand side You will see an arrow pointing to the first 2 on the left.
That will allow you to scroll down the list of options until you see....CONVERGANCE!
make the red gun center by using the up/down arrows on right. Then add the next 2 until you see a white X or cross.
This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.
