Re: Sony KDl-70R550A bad screen or backlight??

Seeing as this model is edge-lit it would seem one or more of the LED's have shorted.

Re: LG 50PK550 EAX61392501/10 EAY60968801 clicks and shuts off immediately

Check for cold solder on the underside of the board, pretty common.

Re: Repair LG 60UF770V

It's not the LVDS cable you want, it's the flat ribbon cables that go from the Tcon to the panel boards.
Swap left for right.

Re: samsung un60j620dafxza backlight led smd diode

I haven't yet found a way to know precisely what LED's are without stripping the TV down.
When you find out let me know.
Best to buy an assortment kit off AliExpress vendor.

Can use packers or...

Re: LG 65uf7690-uh picture problems

This is the Mainboard, I did one recently.
Common fault for the UF series.
Notice the menus are still okay.
There are revised boards available from LG suppliers.

Re: Dick Smith GE6992 Flashing Backlight every 10 secs

I should be clearer, the backlight stays on, it flashes off for a brief second about every 10 seconds.

There is no Backlight option in any of the menus, only the greyed out 'video' which is unselectable.

It is a budget TV, from memory I had another Dick Smith that had no backlight option as well.
