42" HP plasma

I got this tv to try and see if I could fix it. When it is turned on the screen starts out black then develops spots that expand to cover the screen and will not find a display source that is supplied.

I think the panel is physically broken, hope I'm wrong!

Re: 42" HP plasma

the panel isn't cracked but might have the power source for it might be shot, or a leak of the fluid in the screen might be the problem, I don't know.

There are no fluid in a plasma panel it is vacuum with bit of mercury vapor in there.

Without casting aspersions on your intelligence, I have noticed some people have problems distinguishing between Plasma, LCD, and DLP displays. (Recently someone was trying to sell a "42' LCD plasma TV with DLP".) Posting the Model number will go a long way toward eliminating confusion.

To my inexperienced eye, the problem looks more like a cracked LCD panel than any fault possible with a plasma panel.

the back panal states it is a plasma, and the whole fills in with the staticy picture, unlike a cracked screen the will only show the screen until the crack.

Re: 42" HP plasma

Checked the model #, is plasma panel. Way it looked, confirm you have correct voltages as it is marked ont he panel itself on the power supply and the two side boards between the power supply. You have digital multimeter?

If correct, panel lost it's gases/vacuum.
