    It could be that a cement resistor that delivers voltage to the RGB transistors has blown on the CRT board.

    If not then your issue lies in one of the video circuits.

    Most TVs house almost all of the video and color processing circuits in one large scale IC.

        always post the chassis number.
        this helps more than the model.
        rca are ctc-xxx

            Try these

            Bright screen with retrace lines.

              RCA N/A CTC166 BRIGHT SCREEN WITH RETRACE LINES CHECK/REPLACE Q2901 (P/N# ECG159)
              RCA N/A CTC166 BRIGHT SCREEN WITH RETRACE LINES CHECK/REPLACE R5007 AND R5009 correct??

              would i check it with an ohm meter or voltimeter? also what would the spec be on it? thank you for all of your help! i'm glad to see a site like this available to the public!

                Look here for a schematic. The files are not well structured, so look around for a while. Most individual components can be tested with a multi meter.

                One on the TV guys might already know the component. KC8ADU probably has it in his brain somewhere.

                Search here on how to test transistors(Qxxx). Rxxx resistors, if you can still see the lines, you can get the rating from a chart. If not, you need the schematic to get the value.

                  That popping the transistor is sign that CRT is dying.
