You more than likely have a cold solder joint, and moving the tv caused the hair line joint to crack open just enough to prevent current from flowing. But before you start soldering, give it a good inspection inside for a loose connector and/or wire. If no luck, take a solder gun and lightly hit the largest joints first, which are part of the largest component on the circuit board. It has a thick red wire coming out of it that goes to the tube. (Do NOT touch this red wire or disconnect it from the tube. It can still shock you, EVEN WITH THE TV OFF. This is a very high voltage with low current and probabliy will not kill you, but it will hurt very badly, so just be careful and stay away from the big red wire coming out of the tube.) Then resolder all the larger chips, transistors, and capacitors. If still no luck, then resolder the hundreds of smaller joints.

Toshiba 37 inch tube tv wont turn on

Any set that won;t turn on is probably due to a power supply converter which has burned out switching semiconducors. The first thing to do with a set which will not turn on is to check out all the switching gear (ie switchmode converter circuits) and all associated drive and driver semiconductor devices. Once you've done this you will usually find the problem.
