    Is main system memory IC is costly.. is there any problem in Tuner?

    The Knight Jan 09, 2013

    No. It is a cheap to buy, and easily available at most of the electronic spar part shops

  • sinu Feb 27, 2013

    sir can you tell me the IC number as the picture you had given, is not veiwable

  • The Knight
    The Knight Mar 01, 2013

    No. It is cheap to buy. Is a very small IC, having only 8 solder terminals. Even though its physical size is very small, the function of it, when the set works is great.

  • The Knight
    The Knight Mar 02, 2013

    No. The IC will have a number printed on it. You should give that number to them. It usually starts with somewhat 24C XX.

    The Knight May 23, 2013

    Hello The memory IC [shown before] must be defective. This IC is responsible to store the tuning voltage data to different stations. Even though it looks small, its function when set is switched ON is great. Replace it with same number used in your TV. OK?

  • The Knight
    The Knight Jul 04, 2013

    These few lines, that are seen across the screen's top part, is due to a vertical deflection out problem. Probably, a voltage smoothing problem to vertical output IC. Replace the supply filter capacitor to vertical IC's input supply. It will be best to replace all the electrolytic capacitors at the vertical output section circuit. 5 or 6 of them will be there. Change all with same capacitance value. Just replace the supply filter capacitor. It must make the set to work properly.

SOURCE: Options to auto-tune or manual re-tune are greyed

Problem solved!!
According to the Sony website I needed to get a software download in order to fix this problem. I found out how to do this from the manual and realised that the re-tune menu I was looking at was for analogue only. The pictograms onmy remote control are a blurred but the manual helpfully provided a picture showing the correct program "info" button (next to 0) which has options to look at other things, including a "detailed set up" menu on the blue tab, which provides options for software download and re-tune of digital channels.
Incidentally, I discovered that my TV model was not quite as quoted above - it is KD-28DX200U, but expect the same process works for other oldish models.

Some channels missing...


Try to tune the tv in manual search method. If you get means store it manually. Nothing to worry. This is due to malfunction in AUTOMATIC FREQUENCY CONTROL COIL weak. Even you won"t get channels in manual tunning method. Change tuner and afc coil. Problem solved.
