Question about Televison & Video
My Toshiba TV Mod. TV32D60 has trouble turning on, must unplug and replug several times. Switch light flashes each time. Is this a switch problem or something more serious? If it is switch, can new switch be purchased and relaced by myself. Set is 14 years old but perfect picture. I'm asking you because you have made intelligrent reply to others.
Hope you can advise me. Thanks
The problem is not likely to be a switch. I believe that your set has what is called a "switch mode" power supply. This requires oscillation to occur. The oscillation is started by a capacitor circuit. If the cap becomes defective, the oscillation may not start and thus the TV won't come on. Unfortunately this is not a set with which I am intimately familiar so I can not tell you what part to replace. This should be a simple repair however. Check around at a few service shops to see if you can have it examined without a large expense. In the meantime, I'll see if I can find a service manual for it.
One other thing you can try (fi you can solder) is to look for poor solder joints on the main board. If some exist, they can change the circuit characteristics enough to cause what you are seeing. Look for and resolder any joints that appear to be grainy or have rings.
Keep me posted.
