Hi , I`m Jack , I will be helping you todayCan you please send me a reply when you are ready to proceed ?
It does look like your laser may have given up the ghost .
Did this get gradually worse in the last few days/weeks util now ?
Will it play commercially made discs/movies ?
I know you can see my replies (it shows on my side when you look ) but perhaps cannot reply so I will give you an answer and trust you will do the right thing by rating me positively after reading it.
You could try one of those dvd cleaner disc but i would not hold my breath on that one , you most likely have a weak laser that cannot focus on the TOC or data on the disc and nowadays you don`t get this repaired , there are no parts any longer like it used to be , with the prices going down all the time you just replace the unit .
Here is an example of such a cleaning disc ; https://www.amazon.com/Memorex-DVD-Lens-Cleaning-Kit/dp/B00008EM7U
Again don't put too much hope in this , that is a a last ditch attempt .
