My Philips tv is faulty- Anyone got any ideas?
1) Its a full raster with snow - no sound ,only hum.
2) Its electronic tuning with tuning bar . I have noticed that when working properly the bar travels full width of screen but now cuts short 2/3 of way and then starts again.
3) D401 has 33.8v
Same symptom happened a couple of weeks ago and I changed memory battery which cured fault . This time battery is ok. I did wonder if there may be a fault near battery but haven't got this section on my Philips k35 drawing.
Can anyone let me have this section and mains in section where the ac transformer is. 600ma fuse is on this secondary board aswell.
Prior to complete failure set was coming on channel in black and white, it took channel hopping to restore colour. I've no idea why , perhaps someone could explain.
Any help for a 2nd year electronics student would be welcome.
