How do i fix my tv. it is a samsung LN-T4665F and i have no picture. it was working this morning and now i have only a white square in the lower right hand corner.

SOURCE: sound yes, but no picture on tv

If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

Look for bad caps (leaking/bulging top) in the power supply module. Make sure to replace them with good quality caps such as PANASONIC FM/FC series.
