You have to adjust the capacitance value of the capacitor connected to yoke. The capacitor bypasses the scan output signal to yoke. It can be located at the main board. Connected to the collector of the horizontal output to deflection yoke. Decreasing its capacitance value will decrease the width of the picture, and increasing will do vice versa.
Refer any circuit diagram to horizontal scan section to locate this capacitor on board.

SOURCE: Picture on screen is too far to the left

If its only the wide of the screen the problem is with the horizontal transistor near of the flyback, you can also probe the capacitors near, if the problem continues try to change or reconfigurate the EEPROM

What is cost of yoke for panasonic ct tv?

You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width.
There possibliliites for this fault are.
1. Lack of voltage from the SMPS power supply output.
2. Horizontal width capacitor.
3. Horizontal output capacitor.
Check the output voltage from the SMPS section first, and confirm that it is OK.

TV was working fine and then the picture has totally gone, just a Black screen as though it is switched off, Audio on all channels are fine and turns over as normal. No Text no nothing on the screen...

step 1 : at first test your fly back transformer
step 2 : A.C. transformer test
step 3: adjust TV yoke coil

Tv is old the tv CRT-(tv tube) it CRT Yoking circuitry not good as before.The tv deguassing coil in not eleminating all the interference of the tv functions anymore.Move the tv unit to the right or to left like about 3 or 4 inches either sides will help for this problems.

White line only, has sound, may be 14 yrs old.

If there is a white line across the screen, the vertical output section of your TV is faulty. If the line is vertical at the middle of the screen, horizontal deflection yoke doesn't get sweep signal. You haven't mentioned about the full mode number of your RCA TV. Therefore I can only give you this much hint. OK.

Where can i get Yoke coil for my Samsung tv

Yoke coils can be bought from electronic spare part shops of your town. It has specific number, and it should be noted, if can, take the old on in hand as a sample. The replacement procedure will not be easy as you thinks. There are so many adjustments to be done after replacement to get a clear patch free raster. If you have the skill and knoledge, you can. Even a skilled technican will poise some problems while replacement. OK.

I replace horizontal output transistor with new one but it happens the same short

check yoke coil for open ckt, and and check for 12 v dc supply to vertical circuit, sometimes resistor open that supply dc voltage coming from flyback transformer.

Philips 60PP9202/17F Projection Television

How old is this tv?

Projection tvs are all basically the same. Most likely it is the coil unless you can find a short somewhere else in the power supply. The coils tend to go after so much use. If you still want to email the schematic, let me know but I think you are right with thinking that it is the coil and it will need to be replaced.

Let me know if you have any further questions as I would be more than happy to answer them for you
