Excessive brightness and/or washed out picture

There are a number of possibilities including incorrect screen (G2) or bias (G1) voltages, or a problem in the video or blanking circuitry. Any of these could be the result of bad connections as well. A short in the CRT can also result in these symptoms.

First, check for bad connections/cold solder joints by gently prodding with an insulating stick. Check voltages and bias levels.
