A couple days ago when I turned on my set, I had audio but no video. Since this is out of warranty, and doesn't appear to be a cheap "replace the power supply" fix, is this worth repairing? Are there any potential inexpensive / affordable parts that could be broken inside or should I take this thing to the recycling center?

the repair is possibble. One cause for the above mentioned error can be:
no heating at CRT. Check R3466 (large signal panel). If defective replace following components: R3466 - 1R, L5466 - 10uH and R3467 - 1R.
The other cause can be the defective CRT(cathode ray tube) ir there is a high voltage.

If you have any of the following problems you may want to check the site www.TvRepairKits.com for a repair kit. Most of the issue below are fairly common with the older Magnavox projection sets. Symptom: Screen shrinks and expands - may or may not correct itself after the TV warms up. After a few days, weeks, or months of having the shrinking/expanding problem you may loose all audio/video but the power light will remain lit!
Symptom: No Audio or Video but power light is on
Symptom: Audio works but no Video. Power light still work

I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.
A set that has only a 1/2 inch bright line through the middle of the picture, from left to right, has a vertical output IC that is not working correctly. If the 1/2 inch line is in the middle but going up and down, then the horizontal yoke circuit has stopped working. These are problems which should be looked at by a qualified tech, but if the set was purchased 6 months ago then it should still be under the manufacturer's warranty.
