Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Fix the button.

Problem is with the supply voltage to chorma IC. Contact any service tech: In most cases, some soldering works will be necessary.

I have the same problem! Was you able to fix it?

Check and replace its main digital processor board.

Make sure the system is off.

Hold down the Power Button for 5-6 seconds - until you hear the second beep.
This resets the video settings to defaults (standard video output).
Power up the PS3 again and it should auto-detect the hdmi at this point.

If that does not work use the original audio/video cable that came with the system, power it on, then adjust the video settings and try the hdmi cable again.

Might be some loose solder terminal/s at its horizontal output section. The set should be checked.

hi all the black screen solution for me was this (this is assuming you have alba brand tvs and have the black screen BUT can still hear the sound) i after much fekkin around with it eventually found the solution in it (its the bloody backlight brightness in the settings you need to turn it from high TO LOW) ....... now this can be a bit tricky because usually when you have the black screen problem if u unplug the tv for a few hours and plug it back in you only get or should get probably like 30-1min of picture time before the picture goes black so u have to be reallllly fast with the menu button to get into settings before the picture dies (i learned the sequence for my alba lcd32880hdf) it was the following (for this part use the remotes arrows the one with the ok button usually in the centre of them) turn the tv on then click menu then press the up key 2 times then press ok then use the right arrow/button twice (although u cant see what ur doing ur navigating the menu hehe) then press the down arrow/button seven times before finally pressing the left arrow/button (once) <-- (now this bit may need to be done twice if you can remember setting ur backlight to max use it twice it will put it on minimum if in doubt only press it the once remember to totally power the tv off before repeating the steps to reset menus default posistions) remember thats the solution i found for my tv stands to reason (since i did infact buy another tv same brand different model which got the same problem) that this could be a solution for all alba tv users try it worked for me 2 times if ur not sure of the menu look up you tv models menu navigation online to find out the buttons you press gl hopefully it works for you too

I would suspect that the optical pickup is faulty. However Alba sets are manufactured in Albania therefore parts are not readily available.
