Anything over $10 is way out of line. Look on Facebook or Craigs list for a free TV. They are always giving those old things away. The power cord could be wrapped around the antenna and not cause hum. Probably a filter capacitor needs replacing. If you had some on hand, open the TV up and just hold the leads of the new one across the capacitors and find the one where the hum quits . |
| Jeroni Paul <JERONI.PAUL@terra.es>: Jul 15 08:47AM -0700 CRTs are better as they generate the required light only, unlike LCD where the backlight is always full on no matter the screen contents. This is an advantage as far as efficiency goes. Also LCD require more digital processing. At the end the energy wasted to run both is similar, just look at the rated power consumption, you may be surprised. 28" CRT TVs take 100W typ. while similar size LCD are rated 130W typ. |

See if you can see any small black plastic rectangles on the amp or speaker terminal board (relays). Tap on them with a plastic or wood stick. If the center channel comes back, replace the relay or resolder the connections to it if they look bad. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |
