This looks like a problem with the Hv Voltage section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, or have this done by a qualified TV technician.

Or check the voltage test points on the HV / Horizontal board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.

I would suggest that if you do not have a background in electronics that you have a qualified electronics technician who knows TV take a look at your set and perform these test.

I hope this helps,
Thank you,

It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

This is problem of convergence output chips failure and it is fixable.
