    Thanks ginko,

    When you say inside your TV, are you saying the actual cable connections or something within the TV box itself? This TV is mounted on a wall.

    When you say ribbon cable, what does it look like?

    I'm headed to work in a flash. I may not get back to this until this evening.

    Check the lcd cable and cable connectors inside your tv, if ribbon cable is out of place you have similar problems

    I had the following post from a sharp rep. regarding your model on sharp avs forum. I do not know if it can be related to your problem:

    A capacitor was miss-marked from the factory. The stamp on the
    component said 100uf and it was actually 10uf. Caused all kinds of
    power issues. They come in 5,000 unit rolls for the auto insertion

    If you own a Sharp Aquos *D4/6U Model and have been having any of the following problems:

    1. Unit turning itself on/off at random times
    Unit locking up and fails to respond to remote or set-top butons, unit
    must be unpluged and plug in again to get set to respond.

    contact Sharp at 1-800-BE-SHARP (237-4277) and report the problem,
    Sharp will give you a Case # that you will need if any service is to be
    needed or done.

    Sharp has released a firmware fix/upgrade as
    of 2/27/05 to try and correct these issues. I have already received
    this firmware upgrade as of 2/28/06, from my local Official Sharp
    Repair Center but have yet had time to really monitor my set for any
    improvement. Below is a link to the AVSfourms where you can post on any
    of these issues you may be having with your Unit. The thread is
    monitored by a Sharp Rep (Mike53 The Sharp Guy) and he will be glad to
    help anyone as much as he can.

    Check first the lcd display connectors as well, if they are ok you may need tou upgrade tv firmware.

    You need to disassemble your TV (not the box) and the cable is a flat ribbon connected on one side to the lcd display. You need some electronic DIY skills, if you are not experienced in DIY electronics, I suggest contacting first Sharp, to check if you are affected from bug descripted above, and eventually ask them how to do a firmware upgrade, that should not be too difficult.

    Do also a hard-reset using a paper clip on the bottom hole next to the three coax inputs.

    If you have to work inside your TV ensure that you have proper skills and experience, it is a delicate, fragile (and expensive) device, consider calling in a repairman if you do not feel safe working inside your tv.

The light in the middle bottom of screen is blinking with no picture

These blinks [flashes] are fault indication. You can get an idea about the faulty stage circuit inside the TV, by the number of these blinks. Count it carefully, by switching it ON and OFF, more than 2 times at least, so that, you can make sure about the number of these blinks. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view.
