Question about Toshiba 50H71 50" Rear Projection Television
I have a toshiba 50h71 and I just changed the convergence chips last night. I tried to power it on last night and it is giving me a red blinking light. I checked all of the connection on the board that I had to disconnect in order to solder the chips and they are connected correctly. I know that this sometimes means that the TV is in "safe mode" or something like that so I left it unplugged all night and it still wont work. What could the problem be now?
I have the exact same TV and problem. I can't fine resistors R931, 932 etc, but I found 3 open fuses F850, F851, F852 (pico fuses I think) so I am going to change those but must assume they blew for a reason, right???
Wish I could find those specfic resistors.

Ok thanks I will go buy a ohms meter tomorrow and try sometime this week to find out what the problem is.

Did you check to be certain none of the resistors were burned or open that power the ICs ? This is fairly common for one or two of the convergenvce resistors to be open when the ICs go out. Also double check the iC pins to insure that none of the pins are bridged with solder. If you need more assistance please let me know.
