Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
By not full I assume you mean the picture is reduced in size all round. If this is the case then you most likely have a power supply problem. Check the HT voltage, if this is low then check all electrolytic capacitors in the power supply for reduction in value.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.
