Toshiba 50H72 have blue and yellow ghosts


Sounds like your convergence circuit went out. It lines up the red,green and blue picture tubes so the colors are lined up. Usually these TVs all use the same type of IC chips called "STKs" both usually get replaced along with any resistors etc.. around these chips that may have burned up. Depending on who fixes it could be around $300-400 parts and labor.

Toshiba 50h72 wavy and jumping pic/hypermodule part numbr


Most Hyper modules are no longer available from Toshiba.
Hyper modules go bad due to problems in the power supply.
Which also needs attention.
We have developed a method of repairing the modules.
We are a Toshiba dealer in Milwaukee.
Note: What you read on the Internet is only a guess. You guess at you own expense and risk.
A dealer assumes that risk for you and provides a warranty.

The red seems to be out of place on my toshiba 50h72 projection t


Replace both convergence ICs they are stk392-110 you will also need at least the six 1.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link and they provide free installation instructions so you can do the repair yourself.

Toshiba 50H72 problem plz help!


ok well both of you have had the same problem i did... to fix the picture problem check the circuit board pd0074 its the yellowish looking one next to the green one which has the ic's on them... ok on the pd0074 board look for fuses f470, f850, and the f851 to see if they are blown the f470 is what turns the tv on and the f850 and f851 are what protect the convergence ic's chances are they are blown.... the sound i don't know how to fix that problem but i would check all the fuses on that board to find out if one more is blown that what i did but the only thing is that i could get the actually fuses for the tv i was told by a tv repairman in my town to just take 2 wires sodder them on to the fuse and take a glass fuse and put electrical tape around them and it worked like a charm... so i hope this helps you.... the most i spent was 30 dollars for the ic's and the fuses all together and i was quoted at 450 to do what i did myself

The Hyper Module Is Defective / It Is Located Behind The Jack Panel On The Signal Board.
More specifically the 11 16v/10mf caps on that board need to be replaced... Not expensive, I do them for under $100.00 dollars..
