I have a 14R21 Toshiba old TV and still not consider it as a junk. The problem now was after few minutes viewing it suddenly turns off and on and you can hear a sound something a relay clicking. No abnormality observed from the CRT. About 5-10 minutes of turning on/off with the standby power monitor LED blinking red/green/off then goes powered on and again a few minutes again problem occurs. Pls. advise if what have to check on the circuit. Thanks! |
