Now, just a guess: presuming you will find that CRT tube, maybe the job of buying and replacig the CRT tube of your TV might cost you more then a new flat panel TV? I don't know..

How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

U have tools like a soldering iron and roll of solders?Fixed it by resoldering the tv video board pins connecttions sockets pins between tv video board and the CRT-(tv tube).

Most of the times in the back of the board it connected to it or a high voltatage wire from the CRT tubes.They're arcing a small light,like lighting strike and making buzzing sound,that indicated the CRT tubes are not taking any more high voltages from the FBT- flyback transformer.The other times just CRT tubes those glasses holding those CRTS tubes fillerments look very old and fillerment in sides not as bright as the other CRT tubes.Very saldum but very small cracks causes by heat over times.

this was the display of your tv.. it been worth repairing, but it was most likely replace if the problem was big.

check for bad solders on the crt socket . If it turns off again try running the tv with the crt socket off the tube but 1st try to time how it takes for the tv to turn off then disconnect the crt socket. If it does not turn off the tube may be bad, if it does not turn off check the voltages at the crt socket and see if all the voltages at the colour outputs are close to the same, if so then you have a bad tube when you connect the tube and the voltages change conciderably the tube is gone
