hitachi 50ux14b has shrunken picture on the bootom of the screen. I got one response that said vertical IC and/or 100uf@35v and 220uf@35v capacitors. I cant find any capacitors of this size on the board. Are there any available board location numbers to find these capacitors?
I have a lot of schematics on file but not the one for this model---ap33 chassis--usually if you remove the front speaker grill and inspection plate behind it---you will see the vertical output chip near dead center and just a little to the left on a heat sink with fins---It should be an IC with 9-13 pins---usually a LA7838 or something similar on the front of it; the caps you are looking for should all be very close in front or behind it---there is another site where I can try to find the location numbers but it is shut down today and if you cannot find them let me know and I will check tomorrow.

IC 601 (LA7838- mounted on a heat sink )Is the vertical O/P IC and there will be capacitors (C658 and C656)near that IC that need to be replaced also (usually around the value stated earlier ). Let me know if you find the IC

I have a 50" rear projection Hitachi TV. After power is turned on, the sound comes on only ,no picture. I can see that not one of the three lamps turn on. I suspect no power to the tubes but don't know right where to start. Any suggestions?
