Alba TV LCD4288DF 1080P Sound but no picture. On switching on get a very brief flash of the picture then screen goes blank, tried on all inputs with same results. It did sort its self out for a while but now nothing but sound. Any advice please.

Have you tried replacing the cable? They can cause all sorts of trouble.

YOU NEED TO REPLACE BAD CAPS ON MAIN POWER BOARD

If it turns off after a while that's a transistor going hot.
You need a technician to test it for you. If you want to do it yourself
let me know. Good luck.

I have a UA40EH5000M samsung led tv. Suddenly the screen went blank. only sound is there, no display. Which part may have the problem..please suggest..

Is the TV under warranty? If it is don't muck around, contact them straight away as you have a electronic problem with your screen.
Before that make sure the yellow chord is in the visual port and red and white into sound. 2) If thats all good try an experiment, as you know the sound is good, use one of the sound cables to replace the yellow. Is there a picture now? If so replace chord, if not make contact to exchange for warranty.

Ive got a albe Lcd32880HDF And the picture goes off 14 months old sound only?

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

Try unplugging for 36 hours. I had the same problem but with no sound and picture

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

dude just **** ****
