Hi there
Waves are an indication of interverance on the signal. Is it a analogue picture you are watching? If so, you may need a aerial upgrade, or diagnostics on your equipment done.
Hope this helps

Usb charging port fell off inside my Aliph Jawbone Jambox Blue Wave Wireless , opened it up and have to find battary cause circit board broke off with port! wtf the usb port is always coming off stuff


A Jambox is a wireless speaker, not a phone. Anyone claiming to know the answer while referring to phones clearly doesn't know what they're talking about.

The question is mis-filed under cellphones, but the respondents so far don't seem to care that it's not a phone at all. :D

Take a look here: https://www.youtube.com/watch?v=X5APtwqtEps

Apparently this is a very common problem with the Jambox, so contact support first and ask them to replace it.

Radio reception


Cb radio is line of sight. If there is a hill in the way, or some other kind of structure it will block the radio waves.

But also, radio waves, will bounce of the ionosphere and come back down.

So whats probably happening is...

You hear people close because they are near. You can't hear some one some what far away because of hills or something, but you talk to people far away because the are within range of the radio waves bouncing back down to them

Glitchy power


Clearly your TV is shutting down due to a problem. Based on your description, it's hard to tell if you have a vertical or convergence failure. What do you mean by "waving" line ?

it looks like a capacitor problem in power supply circuit. the humming and waving of the picture is caused by a faulty filter capacitor in the power supply circuit. have it check and replaced if found faulty. good luck!

I had the same problem and just listed the dang TV on craigslist cuz I didn't want to spend $$$ to fix. I searched the internet to see if I could somehow fix it (not mechanically inclined whatsoever) but low and behold, I did it!!! It's so easy, the worst thing about it is unscrewing the screws! Just be careful when you finally get done unscrewing everything, be cautious when removing the bottom front away because if you yank too hard, there are wires connected to the power buttons in the front. Here it is: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
