Hello, I can tell you from experience that this is an inverter issue. Both the master and the slave have several transformers and sometimes you can't tell if they are damaged or not. I would recommend testing the leads from the inverters to make sure which one of the two is the one causing the dim picture.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

Hello.
Normally T-Con board have nothing to do with powering up of TV. It's only affecting image when TV is on. So we can discard T-Con as a suspect for now.
Remove "new" main board and install the old one. If TV powering up and back light comes on - you've purchased defective Main Board and you should return it for exchange or refund. It happens all the time, boards that they sell most of the time are refurbished and sometime nothing was done and they send defective board to the other customer by error.
In case that TV is not powering up even with the old main board - look for something that you have done during replacement (like forgotten or overlooked connection, broken/bended pins etc.).
Good luck!
Russ.

Hi,
Basically it is problem of LCD Panel (screen) however some times T-Con board replacement fixed the issue (T-Con board is part of lcd panel but some part shop sell it separately). Main board is not related with this kind of problem.
Required T-Con board is available in ShopJimmy.com (click the link to view available boards)
If T-Con board replacement does not solve half screen vertical lines problem then LCD Panel will be replaced and it would cost approx new tv price.
Hope this info will help.
Thanks.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Why is the t-con board in my Toshiba Reza 42HL67 LCD TV repeatedly dying?

Could be just bad luck! It seems unlikely to me that the power supply would take nearly a year to destroy the T-con board!
You could get in touch with Toshiba to see if there is some kind of problem that is cropping up on this model that might cause failure in on the T-con.
