    I didnt mention the picture is washed out also.

  • kupila Jul 23, 2009

    Well I thought that I would give this a try by asking your panel, but after the first individual I am not so sure though I am willing to give someone the benefit of the doubt. The key was that he told me to check the convergence board. Any technician should no there is no convergence board on a LCD.

    thanks for that. It was the same direction I was going but liked to have it verified. I phoned SHOP JIMMY and yes they have one in stock. thanks for that.

Hi,
Most probably LCD Controller Board (T-Con) is bad in that kind of symptoms.
You can get T-Con Board from Shop Jimmy on reasonable price if its in-stock and T-Con board is not available individually in Sony Parts Store so Sony will supply entire LCD Panel along with T-Con board mounted on it that is of course costly item.
Thanks.

    Then you are probably right if is washes and colors are faded but you still get a picture, then it could be a bios or processor

Streak along edge of paper, Canon MF8380Cdw


Print quality issues on these models is usually if not always down to the cartridges used. I bet you are using compatible cartridges. If so just buy a set of genuine ones and I bet the quality will be perfect again.

How do i fix a sony trinitron kv-27526 tv with no picture?


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience.

White horizontal streaks


This sounds like some kind of lens flair. Make sure there are no bright light sources at about 45 degrees to the lens and it should correct this problem. If it is not that then there may be a problem with the CCD, the part that receives the exposure. Without knowing if this is a point and shoot or digital SLR this is the best answer I can give.

No picture


This type of problem may be caused by a dirty video head, people some time try to adjust tracking to take care of this problem this is a mistake. Now to clear up this issue first you put the tracking control mid way in its setting, then you clean the heads of the VCR you can use a head cleaning tape (follow the instructions on the cleaning tape box)for this or if you have experience you use a chamois swab type cleaner (follow the instructions on the package of swabs and liquid cleaner). one the heads are cleaned you acn then try to adjust track to obtain the best picture. If you can not you may have video head problems or a problem in the drum motor (servo) mechanism. In which case I advise taking the unit to a TV repair shop.
