    Thanks for the help.

    The sound is now distorted. Will the formatter board also help with the sound?

  • crzy4help Dec 14, 2007

    Do you have any idea what the cost is for a formatter board? Are we talking over $500.? We are considering just buying a new TV. What would you do?

Hi i have been researching your problem and it seems this happens alot on these types of telly the problem people have been having is with the pcb formatter board and once this was replaced it solved the problem but when you get this replaced make sure to tell them to check the resistors leading to the pcb board as a blown resistor can cause the problem with the pcb board so get these checked as well.

    Hi yes it will solve both problems but found out its not something you can do yourself as the faulty part needs repairing as they dont replace them it could a bad cable connection from driver ics but this is something you will need to call someone out as locating the exact fault without having experiance in fault finding and also having relevent equipment it will be difficult.
    This is a very common fault with all makes and models of this kind of telly hope this sorts you out and you can tell the person you ring the exact fault.
    Also if you take the tell their yourself it will save you money on call out charge and also charge for them to pick up and deliver the telly from and to your house.

    hi id say at a guess about 300 but depends on make and model you might be lucky though if you goto repair shop they usually strip down tellys and keep all good parts so they might have what you need might be wishfull thinkng but you never no best thing to do is ask around and see what prices you get offered but usually the repair only last about a year or so.
    So you could look into repairing and get prices then see if in the long run its worth doing or not sometimes people repair them and then never have another problem but every telly is different so you need to decide is it worth it at end of day.
    If it was me i would price up repair first you might be suprised and get it done cheap then its worth doing youll have to look into it a bit.
    Its not something the average person can do though so shop around and see what price you get

You have a bad LCD control board,It overheats and causes colored lines,screen to darken,or the color go floresent. Also check the power supply for bad caps.
when you have it apart.They usualy go bad on these tv's. It will cause the tv to take longer to come on.Or you have to hit the power button several times to get it on.

If the purple lines only appear when you point the lens INTO the sun or light source, that would be why they appear in the photo. If you have the sun/light source behind you and the purple lines still appear on the screen and in the photo, it's time to get a new camera.

Rolling lines on screen


Sounds like the power supply has a bad capacitor. This problem can inject excessive 60 hz from the AC line into the vertical stabilizing picture system. The hum also my come from the same reason, bad or leaking filter capacitors. Cheaper just to buy a new TV or borrow another TV and connected to your system to see if the problem still occurs.
