SOURCE: red power light keeps blinking and wont come on

The first thing to try is to unplug the unit from the wall for about 15 minutes,if this does not work you will need the assistance of a servicer to diagnose the problem,if you are familiar with tv service you can check the horizontal output transistor for a short,sometimes it fails for no reason and other times it goes bad along with the horizontal output transformer also know as flyback.Be careful if you decide to check this yourself.

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).

SOURCE: TV turns off and power light blinks unpluged andd still does it.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

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.

My toshiba 50hm67 has no sound


If you still have picture, and the sound was working before this--you may have lost the audio amp chip. I hope you are not running a bunch of external speakers on the tv here--this WILL kill that chip !!

I have toshiba 50hm67 replaced lamp...tv worked, then quit working again, and giving blinking yellow lamp error light when turn on...after a few moments tv tries to turn off and back on


OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.

Black Screen


Ok, this is probably what has happened, you say that you have played games on your tv, well the thing is with HD and Plasma Screen tv's is that when you play Hi-Res games on them the games backdrop will burn itself into the screen, causing the screen to turn dark and not reveal the correct picture it should. People need to learn about this!!!!! Playing games on HD and Plasma tv's will screw up your resolution!!!
