Dark screen with weak sound

Hi my tv is lg 32LN5100-TA was working ok power went off then when power came back later after about 4hrs I switch it on and only black screen appears with sound. I use it via a voltage regulator so the power is well stabilized . Thank you.

Same TV. Display visible, but very dark. I assume backlight problem caused by faulty backlight converter. Is it a plug-in module that you can just replace. If so, what is the average cost of such a module in South Africa

@otipet when you say voltage regulator, are you referring to a transformer or a UPS? What is your native voltage? Have you tried a reset? Unplug the set for about 10-15min. Hold the power button down for a short time. After 10-15min hold the power button while plugging the set back in. Let us know what you get.
