    Do you have a range of what it would cost to fix? I live in Indianapolis, IN, USA



    TV is approximately 4 years old. I am trying to figure out if worth fixing or buy a new one.

Hi Peter,
Power on the unit in the dark room then shine with the flashlight directly in the screen after the picture disappeared, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

    If you are going to send it to repair shop they will charged you $300 more or less (service fee) depend upon the shop plus parts. Your inverter board if faulty will cost you $70 or less. Power supply if faulty is repairable and will cost you much less than the inverter board but they will charged you $150 if the entire power supply board is going to replaced. Backlight also cheaper than the inverter board.

Broken tv


I had problems with channels on my Olevia LCD TV. My problem was solved by updating to the latest firmware.

Make sure the USB flash drive is formatted with the right file system, or the set will not see the updated firmware.

Good luck!
