Hello
Welcome
Thanks for using JustAnswer

If you could just answer the below info requests please this will help me a lot thanks!

If you use another input like a dvd does it also flicker on here too please?

Is the flickering rather like a blinking effect ?

Haven't tried it with dvd. You might say it is blinking.

Hi

The problem is either a bad invertor (this controls the backlight) ot poor grounding of the invertor or a bad backlight itself (not good news), the invertor would need to be replaced just to eliminate this as this is the most suspect
If I am able to locate one do you think you can replace it yourself?or do you need a cost on repairs?

Anthony

Customer replied 334 days and 18 hours ago.

Not sure I could do it myself. What is an invertor, is it like a tube, or somekind of chip.

 

And what would be the cost of it (invertor) if I decide to take it on.

Hi

The invertor controls the backlight its a board I would estimate the cost of the invertor to be around $100 from a board pulling site could be less (if I can find one)dont forget you could have a bad backlight in which case you may be able to send the board back but their will be a restocking charge ,if its the backlight then the set wont be worth repairing due to cost however the majority of the time it is the invertor
