My lcd bush tv comes on bush logo comes on then black sreen

its shot

replace the inverter in your tv ............

HI,
Are you sure that there is balck dot on the sreen. Check one more time is it any dust on the screen.
Black spot Means pixel of the Lcd sreen is fault. There are thousands of pixels in an lcd screen. when any of the pixel or a group of pixels become faulty the black spot will appear. Its not possile to rectify the problem other than replacing the LCD panle if its avilable. The avilability of lcd screen is very rare.

Hello
There is some short circuit inside the circuit baord. Normally, T'Con board should be suspected.

Sounds like the backlight or backlight inverter is out on your TV.
You will likely want a seasoned professional to repair this for you assuming the TV is out of warranty.

Use the RCA AVI outlets on the side of the NES and not the RFI (cable) outlet on the rear of the unit. Tune your TV to the appropriate Video Input channel.

If still no signal, try another set of AVI cables.

Try the console on another television.

If no output from the NES, then it will require refurbishment. Click here for more information.

Please let me know how I may assist further.

sounds like your actual tv tubes blew causing no picture usually more expensive to fix than to just buy a new tv bad luck

Hi.

All you can do is leaving the TV unplugged for fifteen or twenty minutes, in the attempt to drain power completely and reset it.

Also disconnect all video cables when you restart TV. If TV is still frozen and does not pass POST screen, then the TV eprom must be reflashed, or the mainboard replaced. This must be done by a technician.

Try unplugging power and check video connections first.

Try pressing the F8 key at the startup (after power-on and before the logo comes up).
Choose "Fail-safe" mode using the arrow keys on your keyboard and press enter twice.

When windows is in failsafe mode there is a number of ways you can fix the problem.

Try this:
Open "My computer", right-click on your harddrive and choose "properties"
From there scan the drive for errors (mark the 2repair automatically") and fix them.
Reboot the pc...

Good luck
