Question about LG RU-17LZ22 17 in. HDTV-Ready LCD Television
Yes, my lg-17lz22 goes black after use on all inputs....cable tv, dvd player, playstation 3......changing channels reveals picture for a few seconds and then it goes black.....changing channels has latency......so does changing inputs from video 1 to video 2 up to video 5.....
Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

In the menu go to CC and set the TV to CC1 as this is a text box appearing for captions. Hope this works!

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.
I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!
