Angelo, I've been in electronics more than 20 years and I still use the shake, rattle and roll method of testing. :) From what you've described you probably have a poor solder joint somewhere on the CRT board or in the vertical deflection. Turn it off, unplug it and leave it sit awhile. After a few hours you can remove the back and carefully inspect the CRT board. That's the little board you'll find plugged onto your picture tube. Be careful NOT to touch the printed circuits. But with your glasses on look at the solder connections on each of the components. If something looks like it has a tiny crack all the way around the solder connection remove the board and resolder that connection... if you find nothing there you can remove the main board and do the same in all the area around the IC's that have metal heat sinks attached to them... If you find something that looks suspicious carefully solder it up... With all that you should find the problem and if not button it up and take it to a repair shop. It isn't too expensive to have some poor solder joints repaired.. In our shop here it would be about a $60 dollar job plus tax. Hope this helps Bill

Hey If you have tried Using remote and side pannels Have you tried another TV to see if its the Cable? Also The clicking sound is normal its the TV's Power-source starting. The fan light I am not sure of but if it happens every-time it should be normal. If the screen gets warm Instantly (Hotish) Then you TV is dead D:

Cannott get a picture on my tv from my DVD/VHS COMBO

Your DVD player should be connected to either the Yellow White Red connections on your TV set (same color to same color -- dvd OUT to tv IN )

OR it should be connected using the RF cables and connected inline AFTER the Direct TV Box....the box would block the DVD; and possibly the Direct TV Master box would apply 19 Volts to the DVD modulator....destroying the modulator.

Always OUTput to INput on the connections...

Also try with a new set of connections. make sure all the ports are ok.

Hope It's resolve all Problem,

Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock.
