Viera t v made loud clicking noise no picture

It's obviously beyond your expertise to repair it yourself. And it's not the sort of problem that can be diagnosed over the internet.
Find a trustworthy repair shop and take it there.

Midland 5001 40 channel cb radio all is fine with the radio except I question one thing there is a chirp that occurs just before the key down it chirps first then keys up and talks fine. Is this something...

Hi Tom

Ya know I have that same radio with the same chirp. I have asked many to tell me if they hear the chirp on the air and no one has heard it but me. I know what it is but i wont fix it due to the fact it is the only radio that does that to me and i think its kinda cute for it to do it. Now to let you in on the secret is that for the radio to go from rx to tx is handled by transistors plus the computer has to give final say so to tx. So the chirp is developed by the switching and computer turn around times to allow you to talk. I hope this helps.

Why is there no picture on my xbox only sound

hi, you can try unplugging the lead from your telly and also from your xbox then with your xbox switched off at mains plug them back in make sure you push it into the telly far enough as this could be your problem also make sure its fitted in xbox properly the problem is usually the telly end so make sure this is fitted correctly, then switch it on and see if it is now working, if it isnt then the chances are your going to need a new lead, if the problem was with the xbox then you would have no sound as well so the problem points towards the lead being at fault.

Also make sure the telly is on the correct channel

Television making chirping noise

Chirping or hissing from the TV is caused by a faulty CRT base socket in 95% of the cases. Replacing the base socket is an easy job, but care must be taken to get the same replacement base socket. You better desolder the existing base and take it to the shop to get one with the similar connections. Good luck.
