SOURCE: No picture, hear sound, television will shut off after a few seconds.

Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).

You now have a defective lamp ballast board. It sometimes is the root cause of lamp failures in these sets. The problem here is that Toshiba does not sell the ballast board independently from the larger, more expensive light engine assy. Call Best Buy back and get a servicer out there. He may have to take the ballast board out of your TV and send it out for rebuilding.

SOURCE: toshiba TP43H95 projection tv has power but no picture

If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: missionelectronics@sbcglobal.net The cost is 375.00 and that includes parts.
Good Luck.

Does this happen on all inputs such as component , S-video etc.,? I have seen this happen only on HDMI in most of the cases. So please verify this and let me know.
