Hi. On Saturday I bought this Vectrex. According to the seller he had lost the brightness adjustment knob and had the sides open. He claimed that they were the only defects. After I paid for the product and hr  put it in the mail he sent me a video of the console running, apparently there is more to it. Someone could explain to me what is going on. Thanks.

first advice is to stop using that vectrex as you run the risk of damaging the screen (screen burn) because that vectrex has the brightness set to maximum.   you need to figure out a way to turn the brightness down.  it should be set at a level so that the white dot in the middle of the screen, just about disappears so then you can no longer see the white dot in the middle of the screen.

 

what u should do next is take the back off of the vectrex (5 screws) and then inspect what is left of the brightness control.  you may get lucky and the brightness control can still be turned from inside the vectrex.  once you set the brightness down so that the white dot in the centre just about disappears, then you wont ever need to touch the brightness control again, so it's not the end of the world that the knob is missing.

u can see the brightness adjustment control in the pic above.

even if the knob is missing i expect it can still be turned using something else, eg. small screwdriver or piece of plastic etc

note: it might be possible to adjust the brightness without removing the vectrex casing,  by instead inserting something through the hole in the vectrex rear casing, but i havnt tried that myself so dont know for sure.  good luck

The level adjustments inside should be set to their correct values as measured with a meter. There may be other issues. You may be able to adjust the controls to get a good picture but it should be set correctly to avoid future damage. The information about correct values is all over the Internet.

It is also possible that the brightness knob is actually missing. Could be it was pushed really hard inside the case. I know this is possible as I was able to close up the vectrex after working on it and forgot to make sure that was poking through the hole. So..there is enough give on the leads off the brightness pot for it to bend back into the case.

Many thanks for all this help  :) .

I have not received the Vec yet, but being a brightness adjustment problem, I feel more comfortable knowing that the seller has not acted in bad faith.
