You simply replace electrolit condensator / elco in the vertical, ranging from 1uf/50v, 100uf/35V, 220uf/50Volt, 1000uf/50volt. elco among those already damaged. because it had dried the liquid electrolyte. to know which part of the vertical, you can check the PCB board. there is usually an area of vertical writing. or known from the IC vertical (standing) stuck to the aluminum cooling plate / heat sink. Part code to elco, with the inscription C. for example C231 etc. Hopefully helpful.

You have a problem in the vertical section of tv, take your fist and hit the top of the tv, if it flickers or fills out you have loose solder joints which is common in that model, if not you need a tv repairman. not to expensive to repair normally

Half screen is blank 42lg20 or 42lg50 when


This is likely to be the T-con board. If the entire screen glows but you have no picture on the second half of the screen then it is the main board, not the backlight inverter. If the screen is half picture and half gray it is the T-con board.


Replacement of one of the above will fix the issue.


Please rate if this helped :)

Sound stays on, but no picture- goes black and stays that way.


This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.

From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.

Please take this in for warranty service and update this when you find out the details.

Thanks,
Dan

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.
