TV powers on fine but has a solid white line across the screen from left to right or from right to left, has a resistor R14509 that is white in color I know it horizional claps. also need to know value of resistor.

I want too learn,they say ask and you shell rececive.

R14509 - 300 ohm 2 Watt 10%

"has a solid white line across the screen from left to right or from right to left" - would be a description of a 'verical claps' (as you would have most likely put it)

"horizional claps" - would be a line running from the top to the bottom of the screen (at the center of the screen).

You are right I stand corrected.
Would you know the kit for the vertcal claps kit?
This is what I think it is Three capacitors 3300mf,25v 1000mf,25v 220mf,25v IC TDA8172 2.resistors R14508 R14509 think. what other components should I be looking could it be the flyback because of the the flowing.
The TDA8172 PIN Connection Schematic defines its lead as follows:
1. Inverting Output
2. Supply Voltage
3. Flyback Generator
4. Ground or Negative Supply
5. Output
6. Output Stage Supply
7. Non-inverting Input
A. Tab connected to Pin 4

Do you have a schematic for this chassis that I may get.

One (or more) of these should suffice ("TRAINNING"):

collapse = claps

Replace all three cap the one 300 ohm resistor and the vertical IC still has a horizontal claps.
Need help please

Voltage measurements on IC pins:
1. Inverting Output
2. Supply Voltage
3. Flyback Generator
4. Ground or Negative Supply
5. Output
6. Output Stage Supply
7. Non-inverting Input
