O.k then

Is the screen just blank with some background light or completely dark like when the tv is off ?
If you are not sure then darken the room and turn the tv off and on again while you observe the screen .
Can you see the tv`s own menu for example ?

By the way , this tv is a rear projection type of tv made in 2003 and with 3 color tubes , not plasma

Sorry but that phone offer did not go through and in any case it was automated from the web site ,not from me and we won`t need it for now anyway unless you`d rather do this on the phone , let me know.

No light. Volume Only
Expert:  Jack replied 1 year ago.

No menu either I take it ?

Is the sound coming from the tv or do you have a sound system beside that ?

Expert:  Jack replied 1 year ago.

Did it quit while watching it or simply would not come on today ?
Any electrical storm or power blackout in your area prior to this ?

O.k then , at this point without being there with tools and meters myself i can tell you that there are quite a few possibilities .
The most common failure points would be the power supply , high voltage and horizontal deflection circuits and possibly convergence circuit although less likely .
This will require some serious troubleshooting at the component level with test equipment to dig out the culprits and I`d say that its not exactly what i would call a "do it yourself" type of job and you would need the help of a local repairman on this one.

A failure in any of the circuits i mentioned above could cost in excess of $300 to have it done at home.

If i may be frank , considering the age of the tv at years old and the fact that you can get a new 50" plasma tv with all the bells and whistles for around or less than $500 .
I would think twice before investing that kind of money into this one.
