ok i recently purhcased this paperweight in my living room, right now the sound works and no picture, the 3 small "tubes" that connect to the ballast are illuminated but no bright light coming through the ballast to the screen.i have checked the the main fuses that power the convergence board that so many posted have suggested,i double checked all the wiring, and found out the con. board (middle board i guess it gives the screen color balance)has been changed six months ago.i have the service manual. but dont know what powers the ballast. all the points i tested with my multimeter are good so far, the only thing i found odd was a resistor that had sum crust on it,possibly burnt.
if you have any info it will help
thx
bump.i doubt wanna miss the world series
there is no ballast in this set, you have picture tubes in this TV not bulbs, a no picture symptom can be from the convergence or the vertical deflection circuit.
i have the service manual, but have yet to find the vertical def. circuit on the schematic, can u point me in the right direction larry dillon?i the convergence board was recently replaced i tested the pico fuses that commonly blow on the power side of the board, like i said before the 3 bulbs on the bottom the piture tubes light up but by no means does it seem the projection side seem to be working.
