I turned my tv on this am and only 1/2 of the screen will show up. The top 1/2 is black and the middle there is the red, blue, green lines forming an arc. The bottom half shows the picture. What went out in this tv and is it something repairable.

Re: TOSHIBA 53HX71 I can only see half the picture
It sounds like the vertical output IC went bad which could be a bad connection or a bad capacitor \. Do not attempt to fix this yourself have a technician do it unless you have experience soldering it shouldn't take very long and it shouldn't cost very much either.

I would suggest when turning set on cold---turn color all the way off and examine screen as set warms up---if red to some degree but gradually becomes black and white the issue is either a "touchy" red screen control on the screen/focus block or a problem on the circuit board plugged to the bottom of the red tube.
I guess the real question is how long until it is normal?
This is a symptom of poor solder connections inside the set. The set will continue to deteriorate until it won't turn on at all. This is essentially a labor only repair and should not be to expensive for any TV service shop. Once this has been repaired, the set should work for many years to come.
These poor connections are caused by the continual heat/cool cycles because of use and is normal.
Most of the time the Hyper Board failing is the cause of this problem. It will eventually get worse where it also affects the HD ins. Unfortunately the Hyper Boards are no longer available from Toshiba and have not been available for quite some time. My suggestion is to coast with it and replace the Set when the HD ins fail.
I have a Toshiba HD LCD tV, model 37AV50U. the screen is black. I still get audio and can change the channels but the screen stays black. It doesn't even show the menu box. Is this something I can fix myself?
I had this problem and paid a repairman to fix it. He said he has seen it often in this model, and immediately repaired it. It works now. He replaced two 18 pin switching modules, about a 1/4" x 2" x 1"; and 3 "micro-caps"(fuses?). It took about 45 minutes and cost over $400.
