Component slowly going bad...perhaps a capacitor. Or just tube going
weak and now something different...chirps usually mean a short in switch
mode power supply - tries to start and stops because of to much current
being drawn...again and again....chirp...chirp...chirp...
If you are not scared of HV, you might wanna open it up, look around
carefully for swollen. leaky or discolored capacitors or exploded
components.... You might see something obvious. If not, well...unless
you have experience in fixing monitors...it will be tough...
Most monitors have slow HV discharge. If not use proper HV discharge
procedure...
Search the net for that model no...some sites have repair briefs that
talk about common problems for certain models...

I almost always blow compressed air into anything I fix when I open it
up - that includes most of the vintage systems I restore/fix/collect.
