Question about Sylvania LC370SS8 Television

1 Answer

Sylvania LCD TV Model # LC370SS8 has bad picture on left side of screen 7" wide from end, but goes away after 3-4 mins. The video is gone or messed up on that whole 7" strip, top to bottom. Looks like two 3.5" strips actually. I need to know what board to order do fix this.

    When you say LCD controller board, do you mean what some people call the T-con board? This is the little board in the top center with the small ribbon wires to it.

    If by "LCD Controller board" you mean T-CON board, then I agree with you. Thanks.

Half your screen having lines can be a couple of things, one of which you can attempt yourself (well you can try it all, but only one costs zero money).
Being intermittent I would think it is pretty likely a dirty LVDS cable connection which may just need to be reseated and cleaned (we can only hope), or possibly replaced.



Please understand that by opening a TV you are exposing yourself to many dangers. Be sure that the set is un-plugged and keep one hand behind your back whenever possible to avoid a shock through the heart as this CAN KILL YOU. If you have zero electronic experience I would not attempt this repair.



Otherwise, this is a rather simple procedure, and safe if the set is unplugged and you use common electrical sense (which you probably have). Color abnormalities could also be a bad LCD controller, which translates the digital signal into one readable by the panel itself.



Take the back off of the set and find a 30 pin connector (there should only be two or boards not counting the scalar.) Usual orientation for the connection to reseat is the top, middle circuit board. be careful as it is easy to damage.



You could either use contact cleaner (on both ends of course) or you could just reseat it first (I recommend just reseating it without cleaner).



If that doesn't work then it is either the main signal board OR the LCD controller, main board is probably going to be $250 or so, LCD controller about the same if you can find it.

Let me know how this works out.

My Sony BRAVIA KDL-46V3000 Television has messed up colors on left side when first turning it on.....after 5 or 10 mins the picture is normal.. Also without turning on the receiver (only TV) can't select...


This also happened to me and may continue to get worse... If it goes away for a while after warming up, then it is the same problem... The LCD panel is probably going out, when that happens the cost to repair it is more than the tv is worth... If it is in warranty then you can have it replaced or fixed.

Well I have a Mitsubishi WS-65413 65 in.

If so how does anyone know how much it would cost to repair/replace & What is a "Convergence Module"?? I don't know if my T.V has one of those or not but if it doesnt is that the problem perhaps?? Please help me or ill be forced to go outside... :-( ..... thanx 4 the help ppl!! -
