A bad flyback will inhibit the protection circuit. This sounds like what's happening.

Audio and picture go dead red light blinks 7 times


A protection circuit has cut in - possibly due to a fault in the line output stage (flyback transformer could be short-circuit and horizontal output transistor could also be shorted).

Assuming the power supply/HT rail is all OK, replace the above parts, touch up any suspect solder joints, check and replace any capacitors (electrolytic and the tuning caps in the collector of the horizontal transistor - always replace these caps (rated at around 2kV - 6kV) whenever you replace the flyback)

What does blinking red light mean on power button and how do we fix it to turn the tv on?


sounds like the flyback,to replace it is very dangerous, if you not fimilar with high voltage 20 to 30,000 volts, it can kill you, be careful. you have to make sure the tv is unpluged from outlet,use a voltage probe or rubber insulated flathead screw driver made with wire and allagator clips. carefuly ground one end of clip to the shield or strap or a good ground from tv. run it under the cap on the picture tubeto discharge it,then turn cap counter clockwise to pull cap off. then turn the board upside down , use a solder ****** and solder iron to remove the flyback. get the # off the flyback,oder orignal or sub.then resolder.

No pict. power button blinks


Chances are you have a bad flyback and two bad electrolytic caps and a retrace cap gone bad. At its best you may have bad grounds under the H.O.T. And that would be under this transistor next to the 100 ohm half watt resistor a coil.Unsolder this coil clean the board contact and replace this coil!

RCA, rear prjetion, 46" tv,no power, ticking sound


Ticking is usually related to the horizontal output and the flyback with the flyback being more suspect. If you need more assistance please let me know
