No picture, no sound, no lights, faint clicking sound, fuse ok

TV appeared normal, and had been working normally earlier in the day. Switched it on, had a nice picture but no sound. After about 10 minutes, the picture went dark. The red light indicating power also went dark. I removed the case and checked the fuse, but it seemed fine. With my ear close to the main circuit board, I could hear a faint clicking sound, about 2 per second. When I disconnected the power cord, the clicking sound stopped, returning when I reapplied power.

    I'm based in Ghana at a U.S. embassy. If I purchased a part mail order or thru a tech shop in the States, do you think a basic TV repair tech here in Ghana could install it? Is it worth the trouble?

LG 32LB530A Tv sound ok faint picture Led backlid off

Hi,
Back light led driver or the led array is faulty. check and confirm the voltage to the led back light from the power supply. normally 35V to 100V according to the brand and model of the tv. Check the voltage if the voltage is somewhere around the above mentioned voltage the then the tv have problem with the led array behind the screen . If the voltage is missing then the led driver is faulty. Normally the led drivers is found integrated to the power supply board. If so then you have to replace the power supply board as a whole.

How do I get the picture on my tv back?

It's could be one of two things (well, generally speaking).

1.) inverter board. You can check this by putting the TV on something that's broadcasting or playing (a channel or an input playing a DVD or something like that, where you can hear the sound) and then take a flashlight and put it directly on the screen so the light is pointed at the screen. Put it as close as you can, it should be touching the screen so you can't see light coming out the side of the flashlight. Can you see the picture faintly moving normally? This usually works on something that's brighter and has lots of onscreen action, I wouldn't choose a documentary on deep space or something like that for this test. But if you can faintly see the picture moving as it normally would it's most likely your inverter board gone bad.

2.) main board. If the other test fails it's probably the main board that's gone bad.

Either of these you might be able to find a replacement on eBay with a tutorial on how to swap out the components on YouTube. If you believe this may be beyond the skillsets you posses, then you may just consider buying a new one as technicians can be expensive and these TVs are getting cheaper and cheaper every day.

good luck!

TV turns on sound but no picture

Turn the tv on and get close to it and see if you can see ghost images. These will be normal images but will be very faint and look like shades of grey. You don;t want to do this in real bright direct light but a normal light or day light works. You can also hold a flashlight up near the edge and see if makes it easier to see.

If you can see an image and have normal sound then your problem is the back lighting system. This can be the lights bulbs or leds or the power supply for them. Repair cost should be under $150. I don't think you have any warranty left but check ASAP if you do as it may not last much longer.

If you have no picture and no sound then this is usually a problem with the receiver section. Can't suggest what cost would be as it can range from cheap to a bunch depending on what is wrong.

As always with any lcd tv or monitor make sure you know what a replacement is worth before you spend repair money. Repairs can sometimes cost close to what a new tv will.

Hd56w58yx1 no picture, sound for only a few seconds

There are capacitors on the power supply board that dry out with age. You can identify them by observing the tops of each of them. They have to be flat, not domed. Some of them may be discolored from heat. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Use a flashlight to shine light near the screen in a 45 degrees angle when the TV is ON, press menu to see if you get fainted dark video in the background. fainted video indicates that the backlight is defective.
This type of failure could be due to a lower backlight inverter voltage as well.

Television

Is this a Toshiba or an RCA? The problem description does not seem to be right. From what your saying though it sounds like there isn't any high voltage. If you are not qualified to work on TVs you probably should take it to a shop for repair.
