1year 5 month old MacBook pro.
OS high sierra, version 10.13.5
No damage and no other issue, upon turning on had vertical and horizontal lines on screen an in the period of three days went from perfectly functioninfo machine to completeLu unusable, cursor doesn’t respond and the entire sc filled up with flickering lines. Is this a known issue?
Try an NVRAM reset:

Try it several times. if that doesn't work it may be a graphics card or CPU issue. In that case make a Genius Bar appointment for a free evaluation:
:-) yeah it’s beyond my capacity. I would like to be better versed with what the problem is before I approach an outside repair/support. Hopefully the service will be better. Also if this is a known issue then Apple is not doing right by customers like me. I reasonably expect the product to work for longer than 17 months. Thank you Macjack
The opt+com+p+r test was done with Apple call support, no result.
At the genius appointment, without any diagnostics tests I was quoted approximately USD500 fee upon site. So I don’t know what the issue is, what caused it, if it’s likely to repeat.. the ‘Genius’ kept repeating (15times)that I have to pay because I am out of warranty. I emailed about the experience to Apple store no response for a week. That was a hour spent with no solution presented. I insisted that he run a diagnostics test and he ran a software test which came all clear. Even I know that this is a hardware issue. Genius refused to run any other diagnostics, ‘it’s not my job’ and said to fix it I have to pay first. The machine is 17 months from purchase and has total malfunction, his response to that was, ‘it was your choice to purchase it’ so am now looking at community suggestions towards fixing it.
Sorry to hear how your issue was handled at the Apple Store, but unless you have excellent technical experience, it doesn't sound like an issue you can repair yourself.
