Did you check the heating points on the tube???I don't think that the FB is bad first you should check a resistor for the heathing.I'm not familiar with the RCA but resistor is about 1ohm.You can also get a 6,3 V for heating from other source and then try,of course you have to disconnect original wires.Then if it works take a piece of isolated wire long enough to get this...Sold one side at the heating point on the CRT board then the other one push trough the ferith of the FB make three or four circles around the ferith and then sold it to another heating point on the CRT board.I did this many times and t works,but I still thing that there is a dead resistor on your way from the FB to the CRT board.

Tv is stuck on channel 66 and cannot turn it


Try turning the TV off and turning it back on. If that doesn't work try going into the menu and performing a program of the TV. Most TV's will have an option to program the channels. It sounds like your TV has only one channel programmed.

Seeing red !


I had a television that went to a bright shade of blue.A friends neighbor worked for sony television plant where the new tubes came down the assembly line.His job was to make sure tubes were working fine,if one color was dominant then his job was to smack the front center of the tube with a rubber mallot to fix the problem.He suggested i try that with my tube while the set was on.It worked and solved my blue problem.Apparently he explained,the gun connections in the tube came loose and to fix it was to smack it this caused the connection to reweld itself.For you I would use the palm of an open hand and smack the tube dead center with a good hard smack.Dont be afraid of breaking the glass because its very thick and strong.Give this a try.Hope it helps.Good luck!

TV went out


Hey Jim, The high voltage protection circuit has gone out on the D-board and will need to be replaced. The fuse to the power supply is probably fine. A good repair tech shouldn't charge over $125 for this and it only takes a couple of hours. Let me know if I can be of further assistance.

Tv will not power up


no reset button ,sorry. The problem you describe is pretty common with this model as its a fault in the horizontal drive circuit or in the main power supply and without the proper service manual as well as the prober tools and equipment this set its not gonna get fixed. there are no panels or user changable boards as it is a solid state set. ptscorp.com could repair this board or exchange it with a referbished board but it would still requir some adjustment that a user may not be able to handle. time to call the pro.. Sorry couldnet help ya more.. Good Luck.

Squealing set


It looks like an output transistor problem. You can't fix it by yourself; you will need to call a service. It will cost you at least 100$, so consider buying a new one good luck
