Entertainment Center: TVs, Stereos, VCRs and DVDs - Panasonic TV, No Picture but Sound

My Panasonic TC25V50R picture has gone today. Although every thing was fine few hours ago when I turned it off.
There is no problem with sound. I can hear all channels sound even from my DVD player but the screen is completely black. Menu, sound bar and channel numbers are also have gone.

I opened back cover and found there was no red light in the end of picture tube. There was some dust that has been cleaned.
Is there anything I can do to fix this problem?

It's a common problem with this set. It's caused by a bad solder connection in the horizontal drive circuit.Without a scope and diagrams you'll have to "shotgun it". I would start by resoldering the connections on and close to the H. O. Transistor,try turnining the set on .If the picture does not come back ,then resolder more connections in the same area until the picture comes back on.These bad connections are normaly very hard to see with the naked eye , so could take a lot of resoldering before you find the right one.

Thanks craftsman_50 for your kind reply.
I am afraid some connections are too small to resold for me.
If it is the only way, I'd like to assign a technician to do it.
