SOURCE: No picture, sound ok

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

SOURCE: DVD plays only in black and white

Hey, I had this problem on Thanksgiving Day, trying to watch a dvd on my mother's HDTV. You should be able to hook up most standard dvd players to hdtvs. First you have 3 cords, mine were red, yellow, and white. The connections go as follows:

HDTV:
Audio| Component. The white cord should be in a white audio slot. The yellow cord should be in a yellow component slot (video) and the red cord should be in a red video component slot labeled Pr/Cr. Make sure you match the component numbers. For instance, if you want to use component one, then hook all of the cords into the slots for component one. Most hdtvs have multiple component hookups ( think multiple "channels" for your game system, dvd player, etc) so it's important that the corresponding cords go to the correct component slots.

DVD:
Match the yellow and white cords to the appropriately colored slots. The red cord should go into the slot labeled component video out Cr/Pr. Not the red audio out. This worked for me. Hope this helps.

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).

It sounds like your T-Con board went out again. You might re-seat your ribbon cables just in case you didn;t get them in good from the last repair. If that doesn't help I would say that your T-con board went out again.
