If the display is permanent one vertical or horizontal lines then it can't be repaired. If it deals with display problem then you can try to repair provided if you can find the lcd controller ic part. Inverter and SMPS of LCD TVs can be repaired and you need to visit this link https://www.jestineyong.com/resources-2/ to look for the LCD TV repair section. If you have no expereince in electronics repair I suggest that you get the Testing Electronic Components ebook first.

my name is belew i am ATM machine technician and also repairing power supplies, one of my customer bought Samsung LCD TV,model:ps43e470,41 inch, after it working for one month its sound output stoped,i reset it and tried to check all setting its OK but still it has no sound for temporary solution i took sound directly from the receiver to external speaker and also i suspect the problem is at main board tried to check components by digital multimeter all are good except ICs.

If all other output don't have sound most probably the mainboard MCU/Flash Rom could have problem.
