Hi @techbuzz
Try shining a flashlight at an angle close to the screen when you hear audio, and check if you can detect any images at all.
They will be very faint so trying this in a darkened room may help.
If you can see images then there's a backlight problem with the TV

Hi @techbuzz
Just verifying that you used a flashlight to try and see if there was a picture as I'm not sure whether you did or not?
If you see images there may be a problem wit the CCFL tube in the screen.

I have already tried. But no picture found.
I have already clean motherboard attatched ribons but shows same result.
Diagnosis 1-- motherboard power connection unplug result tv screen dark or flash light unavailable.
Diagnosis 2 - Power board fuse checked with multimeter beeping sound it means fuse is ok.
What should i do
The backlight should come on and normally I would say that if it didn't then it may be a power board or mainboard problem but the fact that there's sound and the channels can be changed etc indicates that the mainboard is working as is the power board so it may be the screen problem or a mainboard problem.
Can you try different input types just to see if any of them worked e.g. Component video or AV video by connecting a dvd player etc?
What is the signal source you're using now that doesn't work - RF (antenna) or something else?
Please "Unaccept" my answer as it hasn't fixed your problem
