thank you for the help. I have tried to order GE part # 260527 here in Colombia (South America) but no luck. I don't have a schenatic. I looked at another set, and got the OEM # off of the part, but it's from China and no one has one or can cross it. What type of device is VB40? Transistor? FET? Regulator? Any idea what I might try? Thanks again

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
The part number for this is: RCA #260519, but it is listed as no longer available. Your best bet is to call around to a few local repair shops looking for either a new old stock (NOS) one or a used one.
if you take the back off the tell their should be two plastic screws one is view and the other is focus they should be by the arial socket have a look for them if you are unsure take it to repair shop they should do this for next to nothing hope this is some help ...............................................
the resistor overheated as a result of the diode or the capacitor went bad. Your gonna need to get a schematic diagram and find out what the part #s are as you cant just put in any type of diode capacitor or resistor. Also see what thay voltage source feeds and make sure nothing else is shorted.. Good Luck
