followed Larry's instruction to disconnect all plugs going into the
convergence board and VIOLA, the TV turned on, obviously, with
convengence problem on the screen.

Samsung HCN653W would not turn on
I replaced the 2 convergence ICs last night. When I turn the TV on,
the RGB colors are completely OFF! The screen looks just like when
the convergence board is NOT connected. The manual convergence
control in the TV menu can only adjust the B and R only and the G is
not adjustable..... When i tried to play a movie on the DVD, I also
noticed the R is "bowed" on top and bottom. I made sure the 2
convergence ICs are replaced properly. All pins are checked for
accidental shorts.
Do you think the ICs I bought are fakes? I paid $15 each.
Any help is appreciated.
Does anyone have the service manual for the Samsung HCN653W? --THX
Like the article said my friend "IF you have a service manual". You will need to get it and check the supply voltages and make sure you have everything connected correctly. If all the voltages are good, you may only need to adjust the set in the service mode. this is why I recommend that you have the manual. The manual gives you step by step on the correct procedture on the convergence alighnment. Also did you not buy the IC's from the source I mentioned in the article? Also if i am not mistaking I think I also state to replace the entire board. as it was only less then 90 bucks. Let us know how you make out when you get this straghtened out.
