Even if you don't have a scope, you can use your DMM to check all the power rails shown in the service manual to start. If you can verify those are good, you can start checking voltages around transistors associated with the circuits that might have an effect on the brightness.

However, I didn't even solve the problem with the resistor, I found two 516 ohm 1 w ones, I put them in series but it's still the same, but I noticed something that I had never stopped to look at, as soon as I put the white image and the decoder that uses the charge on the screen, the image is clearer, then once it goes to full screen it becomes gray, I also noticed that the white writing on the colored background is white, even the red overlay menus of the decoder when they are small are much brighter and more vivid, however, putting the menus in full screen turns off the brightness, as if it lacked power to keep the image bright at full screen, yet the voltages are correct, on pin 4 of the flyback transformer there are 122v, at the output of D805 near the flyback transformer there are 199v.
