Open the television and follow the power cord to the main power supply board the fuse will be near this cords contact plug check for blown 5amp fuse, if fuse is not blown then power supply took a shock and needs repair.
open the cover of your tv look for the sound IF using a plastic precesion screw driver adjust the IF counter clock wise slowly untill you reach a good sound or clockwise...if nothong happen solder a 0.2 ceramic capacitor to your sound IF at the coil of the IF under the board the IF has two terminals for the coil.sound if is located near the tuner section..there are two IF the video I.F and sound I.F
It may be too late for this advice, but if you live in a lightning prone area, you should consider having a 'whole house surge protector' installed.
The cost should be well under $300 (a lot less if you install it) and with the included insurance (most often for $25,000) it is a good investment.
If your house was struck, I'm surprised you don't have a list of things that no longer work.
It could just be an expired TV.
Looks like the flyback (high voltage transformer and probably the majority of the power board is kaput. It would be cheaper and probably worth your while to invest in a new TV rather than try to fix this one..
hi there, yes it can be fixed, hitting the unit means that you have a cold solder on the board. the sound is in the amplifier section, check some connection at the speakers and amplifier, a cleanning and a reheat of cold solder to the baord is required. ty
it might be due to speaker.
if it is ok then check for
1 loose connection in sound section.
2 speaker wire loose.
3 any capacitor in sound section might be faulty.
4 check supply to sound section
5 loose connector in sound section.
6 sound ic might be defective.
if not tech.person take help from tv tech.
hope this will help.
If it was struck by lightning, the surge would completely fry the insides of your TV. Your TV probably won't work anymore and you may have to consider replacing it. Some TVs have accident warranties so something like this could be protected, but if not, you will have to purchase a new one.
