Need a little help troubleshooting a tv
I bought a used Sanyo DS27930 television for a 2nd tv and there are faint whitish lines running through the screen when I watch [digital] satellite through the coax, also a steady hum. It doesn't happen on component or composite. The picture on coax also isn't as good as the other two. I never noticed the probl... 21 Jun 2010 10:13

Schematics & standards
Using a rectangle for a resistor allows the value to be inserted in it - quite useful where they're close. And therefore 4K7 takes up less room than 4.7K - and a full stop is more easily missed when reading. Similarly a circle for an electrolytic, oval for non electrolytic. After all, an IC is just a box - not a re... 24 Jun 2010 06:22

Sound Technology ST-1700B distortion analyzer measurement pegs meter on low range.
One of my ~30 year old Sound Technology distortion/power analyzers has a problem. It's been sitting around for a number of years because I had a spare. The symptom is that when you are measuring distortion and move the rotary selector switch one step from the 1% range to the .3% range, the meter goes from a nea... 20 Jun 2010 01:24

Schematics & standards
Someone else made a comment in another thread here about weird schematics (like for home appliances). Wanted to get a small discussion going on that topic. My take: there are good and bad standards for schematics. Personally, I can't stand the ones that use rectangle shapes for resistors, instead of the tradit... 19 Jun 2010 05:52

Fusible resistors queries
When did they first arrive and do they always have an unusual body colour? There is a patent reference to 1977 but when would the first appearance in domestic equipment have been ?. Resistors that fail open circuit if a designed-in current capacity weak point is exceeded , fuse-fashion, not just the thermal limit o... 18 Jun 2010 21:17

Sony KV27FS210 stopped working
TV is about 6 or 7 years old and had been taking a while to come on for several days. I'd turn it on, the red led indicator would blink a few times, then it would take a few minutes for the picture to come on, sometimes accompanied by a loud noise. Then there was a surge of some kind in the house, not lightning,... 18 Jun 2010 15:45
