    In some cases there are broken solder connections on the deflection/power board. If you can re-solder the board you may be able to fix. Look for burnt up parts, if you have them replace the board.

Hello,
This is a common problem with the ITC222 chassis, I would check CP120, CP140, CP150 to see if they are bad I suspect CP150 is the one that is bad. Its value is 2200uf 16VDC. It is located on the same board as the IHVT and is in between the Heat sink in the middle of the board.

I hope this helps,

Hello
Actually the fault is with your TVs power supply section. If you want to locate the fault, and to repair yourself, you must have through knoledge in electronic, and skill to locate the faulty components. In short; you must be an experienced service technican to do this work. As power supply voltages will be high, and potential to touch, since all the components in that board will be "Live" while working, you must be very causous too. If you can inform me. I'll send you the service manual to your TV. Upon seeing its schematic, you can determine whether you can do this work by yourself or not. It is in Adobe PDF format document. So I cannot send that file to you by this window. If you want to get it, send your Email address to me by Fixya. Just see it, and determine what to do; whether try to work on it or get it repaired by some well experienced service technician. OK.

There are four bad capacitors on the sweep board in the power supply. Pretty hard to do yourself unless you have some experience.
