I believe this may be a HV/LV power supply problem since this is a common issue in this RCA ITC222 chassis, I posted this earlier and I beleive that it can help you,
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 would also like to say that if possible you should get a qualified TV Technician to repair this set for you, due to the nature of this problem and the dangerous voltages present.
I hope this helps,
Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.
Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.
the panel is bas. it has a diffusion problem.most extended warranty companies require you to let the shop try 3 times to repair for the same problem. on the 4th time they talk replacement.
best to read the contract.
When the senior service tech changed our bulb, I watched very carefully, and he said there is an electrical contact towards the rear of where the bulb goes in that bends very easily and that care is required not to damage or bend that connector. His assistant tech then bent the thing, and the senior tech had to straighten it out properly. All the while, he talked about how delicate this connector is. Hope this is helpful to you. It sounds like what he was talking about.
It sounds like the high voltage distribution block but that is not the cause of your problems,the tuners you talk about are the picture tubes ,one for each color,the blue picture tube was arking and you got lucky and got 6 more months of use, it and might have corrected when you drop it but now is the red doing it and you need to do the same but it might not work this time,dont be surprise.Be carefull while trying things in the back,there are high voltages there and is not safe unless you are familiar with tv service.
