screen gone dimmer. LG tv 2014. Can't Post

LG 55LA620V. 2014. Worked well and am reluctant to scrap it.
Recently the screen image and brightness went darker but still viewable. Have reset it back to manufacture. All picture adjustments work as they should and even image across the screen. Some loss of definition. All adjustments are on maximum.

Internet searches revealed; faulty power panel to supplying enough juice to LED's etc?

All help appreciated and yes I am fairly competent to repair it. John.

If I can repair it it will be donated to a local charity'Save the Family' where they have been displaced to temporary housing.

I would recommend replacing the power supply board or LED driver if yours is separate from the power supply although they rarely are in LGs. Tvpartstoday usually has cheap ones & shopjimmy.com is reputable also but more pricey. Be sure to order by part number and not model number. That’s how a lot of diy’ers mess up. T
