Question about RCA F36674ET 36" TV
That set is a CTC197 chassis with a common problem - flyback or more commonly referred to as the FBT...
The FBT is a high voltage transformer which delivers a great deal of voltage to the crt to light the tube. The FBT is RCA p/n# 237502 and a ring test can confirm its failure. Another shortcut technicians use is to unsolder the collector of the HOT and power the set. If it powers with up and has audio you're in business, just replace the FBT and it's recommended to replace R14704 its an 82k ohm- 1/2w resistor and C14710 a .01/1kv cap as well. I believe if you order these as a kit, (ie: original RCA FBT), the two other parts are included - but ask to make sure.
You might also check for continuity across E & B of the HOT with a multi-meter while you're in there and if you get any resistance at all the HOT is shorted also... Or for simple reliability just replace it anyway.
Hope this helps!
