Typical failure for all plasma tv's is a blown Y-sustain board. Another high failure for all tv's is dried out bulging capacitors in any of the power boards. You likely have one of these problems.

Audio but there is no picture or brightnessThis is a common issue in many LCD or Plasma sets and it does not have a common solution. In most cases you need to first check for missing voltages on the power supply board and for damaged filter caps there. If good voltages exist then look elsewhere.LCD (not projection) sets often use a back light to provide the light source for the screen unit (display panel) so confirming that the voltage for those is first-if the back lights are being used but not on it is either no voltage, not being turned on by the set, or bad light unit/s.In these sets there are also boards that "Drive" the panel itself. Usually the set will use two boards (some combine both into one large board---names vary but are Inverters, Y-boards (Y means video) T-con boards etc. Usually in this case only one half of the screen will be black but it is possible for it to cause a total loss of brightness also.Plasma sets are similar to some degree but with no back light in most cases.Trouble shooting can be tedious and expensive-Taking one of these sets apart requires some skill as one wrong move and the Display panel can be instantly damaged which is fatal from a repair cost point of view.Other possible solutions include but are not limited to physical problems---loose plugs or connections between boards (look for any plugs held down with tape where they plug into a board). A lot of people with problems play the guessing game-buy and try a board after research which can get expensive and may not fix the set---To gamble or not?I have seen sets where every single board was replaced and set still did not have a picture-means display panel is the problem.The problem can even be the "main" board in some cases -it controls the communication with the panel and if faulty can cause issues.Aside from checking voltages, connections etc. there are a few other considerations---The problem can be the display panel itself---Part cost for that is more than the set cost when new.The panel connects to the boards that drive it with either a multi-pin conventional plug or a RIBBON CABLE.The worst case is if the problem is a ribbon cable etc. bad or damaged INSIDE the panel where it cannot be got at.That means if the case set would cost too much to repair.The connectors where the cable attaches outside of the panel can also develop dirty or loose connections.Fans in units that use them can be an issue if dirty or not moving.As you can see (or not if no brightness) the problem sounds simple but has many possible different causes.Let me know if you have questions as I am here to try to help.SD TECH

I can't find an original replacement stand but there are universal ones available as shown at the link below.

These are easy to fit and use the same mounting points as a VESA Wall Mounting Bracket.

If you need any further assistance then please just ask.

dont understand the ?, sure there are better units than others and better suited units for someones needs, ex. btu rating, if you want heat bigger btu,

it is a a/v hook up not a component hook up
try that like av1 av2 av3
should work a lot better

try this simple test i know its kinda weird, but it helps to know what seems to be the problem.tap your unit three times, while tapping look at the screen, see if it flicker or the screen has picture.then, check all connection, if its all ok. then, you'll need a tech to do a manual troubleshooting.
