The top half of screen does not line up with the bottom half.
The top and bottom are off about1/8 inch. The flyback transformer was replaced recently to fix an original problem. the "tech" told us he has no idea,unless the flyback was a bad one. He suggested using it for about 30 days to see if the flyback shorts out again. RCA model number 32F530TYX1 . Flat screen 32 inch. ser# D494C21BO.

Check out on the main board if the near by capacitor to that transformer is getting short.also check out the voltages if the board is receiving extra voltage then required it gets heated up and the flyback transformer gets short due to it
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You have no power because you didn't fix 2 or 3 electrolytic capacitors when you saw warning signs. Warning signs start as horizontal lines every half inch or so. Black bars on the top and bottom, then collapsing to a horizontal line, then complete failure.
You will need a horizontal output transistor, the aforementioned electrolytic capacitors, a voltage rectifier, possibly a high voltage coil called a flyback transformer, wire wound resistor, maybe a low resistance resistor, maybe a high voltage capacitor. In some tvs you need an EPROM ic. I hope you can find someone with the knowledge and expertise these days when the modern throwaway society put almost all electronic repair shops out of business. It may cost about $300 - $400 to get repaired or you can get a modern flat-screen tv for $800 - $1,000 and reinvest that money.
The problem is in the flyback transformer, or there is a open resistor in the video output, one possible solution is adjust the screen control on the flyback transformer a very slight tweak anti-clockwise, this in a lot of cases will fix the problem, but you must use extreme care, "high voltage danger"
there seems to be a problem in the horizontal circuit...there is a control on the flyback transformer that is labeled "screen". (you'll have to take the back off) The flyback is the component that looks sort of round with the red high voltage lead coming out the top and connecting to the top of the picture tube.On the back of the flyback there will be 2 or 3 controls if 2 there will be 1 focus and 1 screen, if 3 there are 2 focus and 1 screen..using an insulated flat blade screwdriver, slowly turn the screen control counterclockwise to see if this will make the lines go away...if not then there is a horizontal cicuit fault and quit possibly a pincushion problem(hourglass effect)..these will need to be checked by a service shop
Sorry, that is common for generic replacement xformers for
your make / model . There are some adjustments to minimize
the effect in servicer menu...............you can try turning down the
screen control a bit....................T.
When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.
Did you adjust the two controls on the new flyback? The top one is almost always the focus control and the bottom is the G2/screen control (brightness) If you adjust the G2 do it until the picture looks normal, too high and you will get retrace lines through the picture.
