It seem like a convergence trouble. I tink it is a ITC222 chassis in this set. If it is, you probleme is eeprom for convergence need to be reprogrammed and cause no power on convergence board.
OK., I know this set very well. It almost never has a convergence problem.
With the set unplugged, remove the back cover--there is a small circuit board mounted ABOVE the main boards--it is about 10 inches wide and 4 inches tall---On the far right side of it are several DIODES---two are much larger then the rest--what usually happens is one of the large diodes is shorted--5 dollar part---the board only has a few plugs and 4 screws that hold it in---easy to remove--check all the diodes(the two large ones first)
If either of the large diodes read like a fuse you FOUND YOUR TROUBLE.
LET me know if you need ANY help or Advice--I am here to help people---I have seen several sets identical to yours with the problem you describe.
Not haveing the convergence option on this set is a clear indication you have the fl231 fuse problem. this is a simple repair and i see it all the time at the shop. I would suggest you read the "fl231 fuse problem in the tips and tricks section of this website. others have repaired this for less than 10 dollars and about an hour. if you have any trouble be sure to let me know
hello it sound like you've got convergance trouble have you tryed convergance setting if so and this hasn't worked the you will have to change the convergance chips get an engineer to give you quote it's a big job trust me i've done a couple myself all the best
Is the picture bowed in too. first consult "the fl231 problem" article under the tip and tricks section under my profile. THis MAY be the problem. Otherwise you have a convergence issue. convergence is controled by three cuicit boards in this set. Setting the convergence on this set is tricky. try autoconvergence see how far it gets. let me know and i help you trouble shoot further
convergence for the rca itc222 is set individually for digital and analog tuner. Most of time the set will have to be converge in service mode. as a tech i would not recommend getting intoservice mode. but the key is the the convergence has to be set indiviadually for each tuner. You could try autoconverging in digital or even manualy converging
go to this link and leave them a email with your model number and what symptoms your set is displaying. they will help you determine which part is causing the trouble, and they have any part you would need for your model RCA. Here is the link. http://servicemanuals.vstore.ca/
Did you replace the STK convergence IC's yet? If not, thats your trouble, or you have a plug in the wrong place. i doubt if the yolk is bad, as that would most likly blow out the horizontal output transistor and the set would be dead. Good Luck,
