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

Power but no picture


the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com
---------
if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.

This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.

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.

Picture gone.


You have bad conv. ic's.On these sets when the ic's go bad it will usually pop a fuse or burn up a few safety resistors,causing ith video to go away.

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..

Blue screen with no picture


THERE COULD BE A PROBLEM WITH YOUR SCART LEAD OR AERIAL,CHECK THEM BOTH NORMALLY A BLUE SCREEN WOULD BE VISIBLE IF THE SCART WAS LOOSE OR YOUR CHANNELS HAVENT BEEN TUNED IN.
