Disconnect the flyback

Does the red lead connection on top of the flyback transformer unplug. ? I am afraid to pull very hard on it. It is covered with a bullet shaped boot.

    Yes thankyou, I did plan to discharge it, I have been zapped before also. I cannot get this RP 61 inch into service position without pulling one the 3 high voltage leads. I have never had this problem before. I think it was put together wrong at the factory and the lead wire is too short to slide the chassis out. Is there a procedure for this removal of the lead from the HV transfmormer.

Do not touch the flyback...DANGEROUS HIGH voltage.You have to have professional equipment to mess with it!

    I am sorry ,I did not mean for you to take it that way.The capacitor holds high amounts of voltage for a long time,even after it has been disconnected.I watched my electronics instructor years ago get shocked when discharging a unit that had been unplugged for days and he was using the proper equipment.Again I apoloize if I have offended you in any way.I just didn't want you to get hurt and I was just replying as fast as I read you question.

The words on the display are blurry the hole screen seems a little blurry tried contrast and sharpness dose not help

This can be corrected. You will need to use caution. Pull the back cover off. You will see a flyback transformer. You will note, that a suction cup is connected to the back of the picture tube. Follow the red lead and you will see the flyback transfomer. You will also see, two potentiometers on this transformer. The top knob will correct the focus you are talking about. The bottom knob will increase or decrease the voltage to the picture tube. Just work with the top pots. It will say focus on the knob. Turn back and forth as you watch the lettering of an informational program. This will be helpful. Thanks for asking and show all hands of support!

Leave the CRT's alone!!!!! You will ruin them. The red wires come out of the Fly-back. Pull the rubber caps up and then with a twisting motion pull each red wire out 1 at a time.

How difficult would this be to replace? (flyback transformer)

Not very hard but you MUST discharge the stored voltage or be electrocuted.
This charge will be there, even when unplugged.. take a medium sized test lead, ground one end to the chassis, and connect the other end to a probe, like screwdriver, and WITH FINGERS BACK, push the probe under the flyback connection on the tube. Listen for large spark, then you are good to go.

TV HARD TO TURN ON POWER KIGHT TURNS ON AND OFF THREE TIMES THEN YOU HAVE TO WAIT THEN PUSH BUTTON AGAIN

Check circuit board with the flyback transformer(the transformer has a thick red wire connected to the top of it)for bulging capacitors. Capacitors are the ones that look like little cans. If you find any then replace them. Also, resolder all the points at the bottom of the flyback transformer. This should fix your problem. If not try using a blow dryer and heat up the back of your t.v. for about 5-10 minutes.

Thomson scenium doesn't start when we switch it on.

First, try to unplug and reset. Second, Remove back cover and check for shorted horizontal output transistor with ohmmeter. If shorted replace flyback. Next, carefully disconnect plug connectors from deflection pcb. No need to disconnect h.v. or screen leads. Remove from plastic frame and look at bottom (solder side) for cracks around pins of flyback transformer. Resolder all pins. Last, look for two or three bulging capacitors in power supply on same board and replace. Any of these things can cause a dead set. Good luck, Russmann.

Panasonic PT-53WXD63G Flyback, H.O.T., and Triper

The small wires are disconnected at the focus and screen control block, and the large HV cable is disconnected from the HV splitter.you may have to reuse the large red wire if the new flyback doesnt have the HV lead attached. The Hot is the horizontal output transistor its mounted to a aluminum heat sink near the flyback.

Could I possibly have a bad flyback transformer

I would try resoldering the flyback connections on the Circuit board. if the flyback was defective it would operate and you usually get 3 blinks on the LED indicator. Sounds more like a solder issue.
