Question about Toshiba TP43H95 43" Rear Projection Television

1 Answer

I have a 1998 Toshiba TP43H95 I want to fix myself

I am unable to find a schematic to download for free or buy. Picture and audio come on and then it shuts down with the led blinking by the power button. I am thinking it might be 2 IC's STK 392-110 from some searching on the net. I can not find these without the schematic. Anything else it might be.

    the blinking light is a code as to what might be wrong or area to look in. could be the ics all right.What does the picture look like while it is on or is it on long enough for you to see. Like bow in colors. The ic are mounted on big fin heat sink should be black with about 9 or so pins out one edge soldered into board.

If it shuts off and then the power light starts blinking red that is usually indicative of the convergence ICs that you are refering to (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
Good Luck.

Dont have the remote to aline the colors toshiba tp43h95


You cannot complete the convergence adjustment on most TVs without the remote. You can usually use a good quality universal remote to complete the tast, such as a logitech harmony. If you know someone that has one then its free, but to buy the harmony is more then just to buy a new toshiba remote, which you can get here:
http://www.partstore.com/Part/Toshiba/Toshiba/23306269/New.aspx?ModelMfgName=Toshiba&ModelBrandName=Toshiba&ModelNumber=TP43H95

Its part number is: 23306269 so you can also seach around online for it.

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.

This sounds like a convergence problem. This is a common problem that is usually fixed 98% of the time by re-placing the STK392-020 ic or STK392-110, and check the fuse devices on the covergence PCB. I'm sure the actual parts numbers depend on the peticular brand. Good Luck!

TV has power but no picture.


If you know how to read a schematic diagram and have the proper tools then you should be able to fix the set. The first thing and most common for your symptom is a bad regulator IC in the main power supply It will be standind up on a heat sink and start with STR and have 4 numbers after it. Now it could also be a problem in the sweep circuit but not to many faklures there. I have seen once that a blow audio output IC shorting out cause the entire set to shut down and it did take out the regulator IC with it Too. A shop repair for a set like this can run around 250 all the way up to 500 bucks depending on what the fault is. Hope this helps ya. Good Luck
