Tv come on but cant clear the picture from turning red and black how can I get a clear picture?


Without knowing anything about your Tv make or model this is hard; but there should be a reset button in your menues to restore all settings to factory default. Find and use that. However I am suspicious and think the set needs reapir.

My 55" lcd tv has a picture which is clear on the right and fades to black on the left. Which component do I need to replace???


Sounds like the backlight bulb on the left is out. May need to replace the bulb, but do all of them at the same time.

Hi. I have an ALBA LCD32880HDF television which I purchased in August 2009 so just outside warrenty. I have been on holiday for a week and had switched the television off at the wall and returned home...


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

Samsung LCD TV, no picture only sound


is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!

Screen/picture


Does the OSD come up "On Screen Display"? if not, it could be power supply related. Switch inputs and see what happens. do you get any video? How about snow for the tuner portion?
Keep me posted. Talk to you later. Jay

I had the same problem with my new TH-50PX60B. I turned the tele on then after 5seconds it would switch off. The standby light would then blink on and off 11 times, pause for a second then flash 11 times. This would continue until the power wasturned off. Note the TV would not turn on for more than 5 seconds.
I solved this problem by turning the tele on and checking the fans at the back. My tele had 3 fans. If one of the fans is not turning, this will be the cause of the problem and the tele will shut down under the Emergency Shutdown System. To clear the fan try blowing on it to free up any dust etc. If that still doesn't work try using a thin instrument (tie wrap etc) to manually turn the fan and free it. Then power off the tele and turn it back on. The tv should work perfectly.
