Hi,
As welcomejee has earlier posted, the exact model number is required to be able to give you specific repair advice. Anything else is generic and therefore might or might not be addressing your concern. Some of which are:
I am tempted to think that you have a CRT conventional TV rather than a PTV. The model number of course would confirm this.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
Regarding your problem: "When I turn it on the audio is fine but the screen only shows about 20% of the picture in the center of the screen"
when this happens on a rear projection TV, the problem regards the light tunnel, probably the mirrors on the light tunnel had moved, or one of them is out of place, and the light beam projected generates picture on part of the screen only.
This is easy repair for any TV repairman that can work on DLPs, he will just need to take apart the back of the TV and inspect the light tunnel.
Well, to repair this tv you need to mention correct model number to get proper service manual, contains all necessary technical information inside.
looking in service manual is like map of city, where to go.
you also need to have screwdrivers, tools, soldering iron or soldering station, volt meter like that.
The convergence feature is used to align the picture tubes inside the
television so the image is projected on the screen evenly without
ghosting.
YOU NEED TO HAVE CHECK ON THIS AREA.
AND ALSO ON THE VIDEO OUTPUT MODULE THIS IS NEAR ON THE CONVERGENCE MODULE CHECK ALSO FOR ANY BURN RESISTOR AND CAPACITOR ON THE VIDEO OUTPUT MODULE..
CHECK FOR ANY BAD SOLDERED ALSO THIS IS VERY COMMON PROBLEM ON TV SETS.
I WILL ADVISED THAT YOU MAY NEED SOMEONE TO DO THIS WORK FOR YOU, IF U HAVE NON IDEA HOW TO DO IT.. ITS TO DANGEROUS TO WORK AND REPAIR THAT AREA.
KEEP ME UPDATED..

I have an older 50" projector tv and it has no sound and will not except a remote. The problem is the pc boards are burnt, I have a picture nothing else. In the back on the bottom is an access panel that can be removed to access the pc boards. MAKE SURE THE TV IS UNPLUGGED!!! To clean the boards use a contact or pc board cleaner. This comes in an aersal can and you can spray the boards literaly saturating them. If this doesn't work one or more boards are burnt but repairable.
No your tv is perfect and it can be definately fixed but as u said you dont have technical knowledge about tv. just take it to the repair center as its the problem of your convergence ---ics--- and allignment problem on the main board.
it will not cost u more then $200 plus service charge of the technician to get it repaired

If I have a friend who can work on TVs what will I need in the way of repairs to get the TV to work normally.
The answer was not to my problem. It concerned a 50" tv without sound. Please refer back to my 36" Toshiba.
The answer I received did not apply to my 36" Toshiba TV. Please review my original question and give me an answer.
