I think you can still get them in some of the stores.. if they have stock, etc.. but online, yeah they seem to be gone 😞
If you only watch a few BASIC channels in that spot (the 1-60 range) the free DTAs are a good option.. but only say if you watch the news, etc only in that location.
With with probably 85%+ channels all in HD now.. i can understand them trying to move away from even needing the SD boxes.. but they still need to make them available, for people with older CRT non widescreen TVs and the like.
I ve made it work by chaning 2 capacitors in the power supply. Using a voltmeter, power was at 8.1v and it is supposed to be at 8.2 v as specs required. I ve found on the internet the culprit: Chinese capacitors. Long story short, Chinese put on the electronic market capacitors that did not had a long life expectancy. I had the same problem on a PC mother board refusing to power up and same problem on a viewsonic 32 inc LCD TV. It is easy to recognise them, the head of the capacitor is not flat anymore.

They are actually the same shape.
So using a scredriver crack open the power supply. You cannot remove the board from the case you will have to bend the case to access the 2 capacitors (near the power cord). Those are 2, 16V 1000 micro farads, plus is outward, minus inward the board. Be careful when desoldering not to burn the surface mounted resistor close to one. I ve payed 3 $CAN for 10 capacitors at the electronic store.
Of course you will void warranty and you will have to do it at your own risk, it was worth trying that.
Chinese capacitors, the story from what I remember reading: Japanese engineer steals the designs/plans for capacitors and goes to China to strike it rich. Chinese company produces said capacitors, but, didn't get it exactly right. End result, millions of failing capacitors in numerous products built by many companies. I have a few monitors that fall into that category.
I know it might might be worth a try but ask a Rogers store if they can test your Cable Box tell them u think the hydro adaptor may be faulty. My godfather had this happen to his and was not in warranty and the store didn't ask any questions and simply OTC'd the hydro adapter only, it was a straight swap as a good will gesture too, no paper work.
A lot of people assume the cable box is dead and end up being forced to buy/rent a new one.
