Hi there, I was watching my 42 inch LG Plasma TV last night, and I heard a click sound and then lost picture, the sound is working OK, what do you think the problem is
I was watching the TV and the image just went black. I can still hear the tv but not picture!
If its a plasma .Then most definitely you have a YSUS,ZSUS and or Y drive board bad..I could not find part numbers for you with model you gave in the LG servicer website..But even if you have only the Y board bad ..It is recommened you change at least both Y and X .unless the Y drive is also bad..Please verify correct model ..I work with LGs all the time and I can get you part numbers..
Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok
Hi sorry i think i miss informed you was thinking of other problem not your sorry.
The problem is deffinately the lamp needs replacing.
Its not expensive to do and is possible to do yourself.
If you think you are capable of doing this yourself then give these a try for the part you need okhttp://www.dlplampsource.com you should be able to get it from their.
But if you are going to replace yourself remember you cant touch the lamp with your bare hands you have to buy some gloves ask in any repair shop and they will tell you the best ones to get because if you touch the lamp and their is any grease or anything on them it will blow the bulb strait away so its not worth the risk.
Let me know how you get on ok.
Hi disregard my first post as this can sometimes be the problem but only usually when the telly is about 3 to 5 years old so dont worry about that it is deffinately the lamp gone ok
Hi ill have another look for you maybe the link i got of mate wasnt right link for your make and model ill have another look for you ill post back and let you know ok sorry for wrong info will post back looking now for you
Hi just spoke to couple of people for you who repair these units in uk they both told me that not lamp problem it is either :
scan drive pcb board or
video buffer pcbs.
Now they tell me both of these are expensive to replace they said it is either one of those or if your lucky then it could be the power supply to those parts ie the correct power not getting to them could be resistor or solder problem but it is usually one of the two problems with the pcbs whilst waiting for reply ill find out where you can get these parts and if it is possible to repair yourself.
Ill look now for you ok
Hi it deffinately wont be lamp problem as plasmas dont have lamps sorry for misinforming you but didnt check the info before researching your problem
Hi the problem will be either of the pcbs so either goto repair shop and ask them to get them for you as the parts are hard to source without sending back to makers but repair shop should tell you about supplier they use as i live in uk its difficult for me to locate in your country.
You could even try using search engine to look for parts.
Let me know how you get on ok
