Question about RCA 20F530T 20" TV
This is a one year old TV and one day I turned it on and the screen was yellow and the picture was yellow ... what could have happened and how can I fix it?
On the kine board,( the small board plugged on the back of the tube.) look for and test rb030,rb050,rb070, all 3 resistors sould read 1000 ohm (or 1k ohm). I suspect one of there resistors are open. if not on ib001 (same board). you can check for these voltages. pin1 2.8v, pin2 2.9v, pin3 2.9v, pin4 0v (ground), pin55.9v, pin6 181v, pin7 104v, pin8 105v, pin9 111v. all voltages are in dc. hope this helps.
