You can contact PTS and see if they rebuild those boards otherwise I would suggest replacing it. The cost is well below that of the set $252 from Sears parts.

Toshiba hyper module. Vertical lines on screen.


change the 10 or so surface mounted bad filter caps in the Hyper module this set uses--the board is no longer available--it can be sent out for rebuild (not toshiba) but that is rather costly (200+)

There are 3 vertical lines on either side of the screen. How can I get rid of them?


This can be a defective T-con module or Control module. Best to have it diagnosed by your local service center. It's to costly to play a guessing game.

50HDX82 rear projection Flicker/Fuzzy and Vertical Purple Lines


The hyper module itself is not an expensive repair about $70 to $100.00 dollars. The tech will simply be replacing about a dozen 16v/10mf smd caps and re-installing it on the signal board. But that doesn't address what he has to do to get to it and get the hyper board off and back on the signal board and that is a bit time consuming.
What I would suggest is to call around to the various shops and ask what they charge for the hyper module repair and see if you can get an off the cuff estimate for around $250.00 dollars.
If you need help finding some reputable shops try TVrepairpros.com for help in finding some of the best technicians available.

Verticle hold transistor?


The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.

Good Luck!

Samsung rear projection tv have vertical black linens up and on tv


you have a bad dmd module and it cost around $750-$800
Happend, because a bad soldering connections in that module. Lines will come on and off. Probably 1 day will stay on. For last 2-3 years im seen that only on hlm and hln series. Probably
happens on other models. but, i never seen that.
Is not that hard to replace that module. You have to remove 2 screws from left side and 1 screw from bottom righ side of module and 4 of them
from around dlp unit unpulg all cables ( i think
3 cables ) that it. Same way install new one in.
but you will need to adjust a module position to get picture to fill whole screen.

Picture has horiz. lines


There is no vertical hold in the tv circuits now adays. You may find a vertical center or a vertical height. Your problem sounds like (if it has PIP Thats Picture in Picture) its in the PIP module and its a small module that stands up and most models of Mistubishi this module is no longer availabvle. The problem with the module is the small pana caps are leaking and ruins the PC traces. I have heard that theres a kit available on E-Bay to jump out this module. Now if its not the PIP model then it could be a few capacitors in the vertical sweep circuit. Also the B+ feed off the Flyback that supplies voltage to the vertical output IC could have a bad or leaky capacitor in the circuit. If your not a tech or solid state troubleshooter theres not much you can do and SHOULD take this set in to a repair center. Good Luck
