I recently upgraded to HDTV and carefully moved my Sony Wega Trinitron to another room. After the move, I can't get the picture back on. Sound comes on, but the red "standby" light continues to blink, and still no picture. What could be the problem aside from jealousy?

Re: Picture won't turn on, but sound does...
Yes i beleive you some stuffs do have a feeling. anyway, the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.

Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.
The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.
The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.
If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.
I think you had an arc in the high voltage circuit which zapped the blue drive circuit to the picture tube. This could have been caused by the high temperatures the your set was subjected to.
