My LG tv (Model number: 32LS3410-UB) has sound, but no picture. When I do the flashlight test I can see a very dark image on the screen. Will replacing the LED driver fix this problem?

If you already tested with the flashlight which is the first step in the blank screen with sound fault then you have to test the LED Backlight supply voltages if you are familiar and good in the electronic repair. First you have to check if bulging capacitors for the LED Backlight drive voltage circuit, replace them. If capacitors are good then you have check the backlight LEDs. The flashlight test proves that the power supply is good and TV is working fine because the sound is ok and picture is fine. Attached videos and links may help you for the repair and replacement of backlight LED strips or LEDs itself depending on the type of LED strips used in your model.

There is sound but no picture. No backlights but can see a picture in dark with flashlight test. LED panel # is D460D3-6Y43-COX. What part would I need to purchase? T

You have check the power supply first .To know how to check the power supply watch the following video. Normally led tvs power supply contains the led drive circuit too. Bot are integrated in the same board. The led drives circuit should have between 30 to 120 volts from the power section depending up on the brand and model number of the TV. If the the voltage is ok then you have problem with the Led driver section section. Either you can try to repair it or can buy a new power board.

I have pictures on my 50" but sound

Look up the model of your tv. A lot of the problem on these 50 inch tvs can be fixed pretty quick. If you know how to safely use a multi-meter the first thing I would do is unscrew the back of the tv and check all fuses. Only do this after you have checked all connections going into and coming out of the tv to make sure they are secure. MAKE SURE IF YOU DO ANY TESTING THAT THE TV HAS BEEN OFF AND UNPLUGGED FOR AT LEAST 5 MINS. once you get the back off check for any obvious burn marks, bulged or leaking capacitors and fuses. If all checks out you will have to test further (if capable) or take it to a TV/ Electronics repair shop. Also check you tube for your brand and model number. they usually have some good videos

OK. It sounds like you have an issue with the wire harness. Disconnect the sensor and with a multi meter check for voltage on the wires. You should get up to 4 volts. DO NOT TOUCH WIRES WITH A TEST LIGHT. This will fry the computer. follow the wire harness throughout the car looking for a damaged ares and repair it.

Battery is showing 13.5 volts on multi-meter but motor is not coming up to full speed turning light is ok. Joints. Wiring looks okjust not as quick as it was.6 weeks ago.chris

your battery may show the 13.5 volts but it is the amps you need to worry about in this will have to have the battery load tested,sounds like the battery has a weak cell or a dead cell.

When convergence out ICs stop working in rear projection TV, picture looks 3D affects.
Need to test/ check supplied volts on convergence out ICs on main board and if volts are OK, replace both ICs.
