| Alien | 3711 PT92 | Sound system changing - enter service mode | Press Text sub page key on r/c whilst holding Vol down button on TV. Using Prg + & - key to navigate thru settings to Option Byte 1. Sound systems appear - at right of each is 0 or 1, press Vol- & + keys to alter settings for PAL I to 1. Press TV on R/C to exit & store. Press & HOLD menu on r/c till the OVERVIEW menu appears, press menu once more until INSTALLATION menu appears. Navigate to sound setting & use Vol - & + keys to alter to PAL-I for UK sound STORE by using Vol + | 14-09-04 |
| Apex | Apex 32" | Apex 32" . When I turn it on, I hear a high pitch noise from inside the TV. It starts to chirp in small intervals, then quickly becomes a single continuous tone. No video signal or sound from the speakers. | :D you have a line op stage problem-remove the line op transistor and check it for sc-with the transistor removed load the power supply ht capacitor with a 40w lamp and switch on-check the ht is correct .
if so your power supply is ok,if your line op transistor is faulty a new one may get you working .Check all soldered joints in the line op stage
