Question about Sova Digital DS205-S32 Television
I have a Sova DS204D-S26 flat screen tv. At first the problem was intermittant, but now the screen is black-no picture- but the sound is ok. All of my connections, including the power cord and supply are fine. Is this problem fixable or does the cost make the repair not worth it?
That type of problem is becoming all too common with plasma and lcd flat screens 32" and above. There are two boards inside the plasma tvs that are called the y-sus and z-sus boards. From my experience the z-board has been the most problem producer with that no picture and sound ok problem. However, the one issue here is that the power to the to the y board goes through the z board. Most techs I know recommend replacing both. The reasoning being that whatever caused one to go bad would also weaken in some way the other. I am not fond of this type of thinking but since I do not have the tv in hand to take signal and voltage measurements I would start with the z board. On the internet you can probably find those boards and through e bay at a good price. They are not hard to spot once you take the back cover off the tv. The y board is usually on the left and the z board on the right. They have like 6 to 8 screws holding them in and three or four connectors that are keyed so you cannot plug them back in wrong. They are also clealy marked on the board itself and usually with a white sticker of some sort. New these boards can cost from $100 to $200 depending on the source. Shopping around you can find it worth fixing in my opinion if you can replace the board your self. Always disconnect all power when you take that cover off. Good luck and God bless. Roberto
