DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?

Hello. I have replaced many DLP chips, as I work for a repair shop. I have seen similar symptoms when the chip isn't seated properly in the mount. There is a gray screw that should be loosened to remove the chip, and tightened when the new one is installed. Most importantly, you must make sure that the chip is seated flat in the socket before tightening the gray screw. Since you have done it once, you should have no problem correcting the issue! ??

T-con board is causing all your problems. You are correct. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

This problems very common on DLP Tvs.This problems known as a convergence problems,it dead.Colors lines R,G,B mis alignment,have colors shadows or 3D pictures.The tv convergence board is dead.Require to be replaced on the tv convergence board 2 STK convergence ICS and some or all it resistors to solved the tv convergence board problems,to solved tv convergence picture problems.The shop,will cost about $300-350 for parts and labors.

The color wheels will never fix an issue like that. The only things that will cause that issue is a bad DMD board which is part of the light engine or the digital board which is not. Freak Squad need to replace the digital board.

There are at least two issues here. First you have bad buffer boards. Second Very possibly a bad X-Main bd and P-Logic bds. Have a trained Samsung tech troubleshoot the set.

Sounds like vertical collapse. Have tech replace vertical ic. Shouldn't be to expensive

needs a DM Board, prity easy to change yourself, if you order one, make sure you give them the version number off the Right side of the TV, will be somthing like SP01, To change - when you take the back off the tv, it will be on the left hand side, have to unplug 3 or 4 connectors, then take the plastic covering off, and it will slide out.

sounds like power supply caps or caps in the dm board

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
