I have a samsung projection TV HCL4715W. The picture went black while the TV was on and since then other than sound, there is no picture. I opened the TV and can't see any light in the CRT. Called in a technician and he said that the deflection board was gone and that there was no high voltage. Suggested $400 to repair it with a replacement board which I refused. Checked online for the price of the board and bought it online for $170.
I replaced the PCB SUB board AA95-00705A, however the TV just made a screeching noise when it was plugged in and the same problem exists again. Any suggestions? Larry D.. help..
Thanks,

So I know that this is a very old post... but my HCL4715W just did the same thing tonight... the picture went away but the sound is still working, also it smelled funny in the room after the issue started. I pulled open the side panel and it was very dusty so I have cleaned it up a bit with a can of air... I have never worked on a tv and really i have no idea what to do... im poor so I dont really feel like buying a new tv... anyone who can help me out?
Still no picture... the red light on the front flashes 9 (10 if you include the start light) times... and the 3 tubes glow a faint orange (you have to turn off the flashlight to see it)
