13" GE tv only works when you unplug it and wait

 Greetings,

 I purchased a GE "kitchen" tv with built in VHS tape player back in 1994 (MODEL #13TVR40 - SERIAL #41742059).  It plays great and the picture is excellent.  Just recently, I could not get it to turn on.  I thought of tossing it out because of the fact that it is 13 years old.  However, after having it unplugged for a period and trying one last time, i discovered it does in fact turn back on and plays great! 

6 Blinks on Sony KP51hw40

Hi,

 My kp51hw40 turned off by itself and the standby light blinks 6 times. I have read 2 different possibilities of what the problem is. 1. is that the A and B board may be bad because +5V is shorted or overloaded. The other is that he d board might be bad.

Does anyone know how I can narrow down what the problem is?

 Thank You

Can't get all the channels on my new TV

Hello,

Can somebody help me with this puzzler?  I bought a "new" TV this morning.  Brought it home, plugged it in, connected the cable, and was pleased to find that it actually works.  However, I am not able to get all of the channels.  It seems as though there should be a button I can click and get the channels above 13.  Any thoughts?

Thank you for your help.

Sony KP-57WV700 Problems

I have a Sony KP57WV700. The problem I have just started. On the left hand side there is a blue shadow. I try the Auto Convergence but this did not help. I also try the manual Convergence but it does not let me move the blue cross far enough to merge with the white Cross. I’m thinking it’s the Convergence amp IC. Have has anyone ever seen this problem and know how to fix?
