I was given this TV today by a neighbor and it won't power up or do anything. I'm very familiar with building pc's and replacing parts and troubleshooting them but have never opened a tv set before to repair one. I enjoy tinkering and I thought I would try to fix this one just for fun. Does anyone have a suggestion for me as where I can start? Replace powersupply? Or am I wasting my time with a 10 yr old tv and should just toss it to the curb? Thanks! firstname.lastname@example.org

It may be arching from the flyback. If you are familiar with tv's remove the plastic case plug it in and turn it on and see if you can see anything visual happening. Make sure not to touch anything and keep a safe distance when inspecting.
The tv has a high voltage problem, sets that last ten years or more have come to the point where a new tv should be considered, because even if you fix it there is good chance something else will go wrong, remember the parts are twelve years old.
Your TV must be equipped with AV inputs (RCA jacks - yellow, white, red) in order to connect this unit. If your TV does not have AV inputs, you will need a RF Modulator to connect the DVD recorder to your TV's antenna/cable input. RF Modulators are available at major electronics retailers such as Radio Shack or Wal-Mart and allow the 3 RCA outs from the recorder to connect to the RF modulator RCA inputs and then you can connect a coaxial cable from the modulator to the TV RF input and select channel 3 or 4 on the TV. The DVD recorder will not pass thru signals to the TV using coaxial cable as far as DVD are concerned.
You either have a bad CRT or a Shorted Red Output IC/Transistor. One other possibility is if
someone turned the Screen Control down if it is accessible from the back of the set.
Hope this helps,
If you have a VCR with RCA inputs and coax (cable) output to TV, try plugging the DVD players RCA outputs (L/R audio, composite video) to VCR RCA inputs. Then select the DVD input on the VCR and it shoud play just as a the VCR does. If you don't have a VCR, an RF modulator might be needed, but a VCR would probably be cheaper.
The horizontal (line) deflection circuit appears to be at fault. This circuit is responsible for the generation of high voltage (tension) that also drives many of the secondary circuits such as the vertical drive, tuner and sound stages. While the main power supply itself is running, a failed secondary stage will give the symptom that you've mentioned. Replacing the line-output transistor is likely to solve the problem. However, this advice is given with the understanding that you are familiar with TV repair. Otherwise please refer servicing to a qualified tech.
If you ONLY have an Antenna or Cable input, you are going to need a Video & Audio to RF converter.. This connects to ya DVD Video & Sound OUT, and then connects to ya sets Antenna IN.
This device converts ya Video & Audio signal to Radio Frequency Signal that can be "Received" by ya set. (Basically a low power TV transmitter)
This is the only way I know of, if ya haven't got any other Inputs into a set.
