Still Caps can hold charge for longer than that. Do you know for sure this is the problem. If not then, you maybe shooting yourself in the foot sort of speak. You would need a desoldering tool, iron or gun. Have you check the cost, because most flyback for projection cost maybe over 100. So it maybe easier and safer to call PTS 18008447871 and give them the tv model and what the problem is.

I just want to know, what is the part number of flyback transformer on my teli panasonic TC-20P1.

Part number is required only if you are ordering with the company and here in this case you can specify the model number as the data base is available with them.
Otherwise the flyback/ line output transformer can be removed and taken to any spares shop to be identified for the replacement.

RCA 52in. Projection TV D52W19B does anyone

Hello butmommy03,

This is the procedure but first I must warn you. You are dealing with one of the most dangerous parts of a TV The High Voltage anode or the CRT and the flyback transformer. That being said this is what you have to do:

1) unplug the TV from the wall or power strip.

2) take the back of the TV, and find the High voltage trippler and using a screwdriver grounded by a clip-lead to the grounding strip touch it to the exposed metal of the input to the High Voltage trippler.

3) using a soldering iron de-solder and remove the wire from the HV trippler.

4) Once this is done, angle the chassis to expose the bottom of the Deflection board, if this is no possible you will have to remove the deflection board to get a look at the bottom, once this is done and you can view the bottom of the board using a soldering iron and a de-soldering pump you can remove the solder from around the pins of the flyback transformer about 10 pins in all. Then remove the screws that hold the flyback in place. this is the procedure you requested,

However again I must ask you not to do this yourself and to get a qualified TV technician to troubleshoot this TV for you.

Thank you,

Flyback transformer and horizontal output transistor change out

There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

Repair shop says Flyback Transformer needs replacement

If you know what you are doing, and you have a good (de)solderstation, you can repaire it yourself, but you don't know if it for sure the transformer. since you did not find the problem yourself, suppose you replace the transformer and your TV does not work !? Even when you repair it yourself, the repair guy shall charge you the cost for his time (I don't know the exact english word for his time checking the TV). And I suppose there is a warranty for his repair. So...
