sony vph1031 brightness problem
 
Hey all, I have a sony 1031qm every thing works good exept the brightness knob. I cant adjust it up or down. I took it to a technition and he told me it was the pix tubes, done nothing and charged me $100. Im sure its just a board as the tubes dont have any wear or burn marks and the picture is perfect other than you cant adjust the brightness.
Has any had this problem or know witch board needs replacing? "HELP" :-(

Have checked with the Pj lamp it might be low. In most cases the problem lies in Bulb.

Applogize for bad advice? Look at the models again.
