Replaced ics, no power

We ended up with a convergence problem on our Samsung Hc-p4752 television and so we replaced the ics as many people have suggested but now the tv will not power on. Any idea what could've gone wrong??

    Hi,

    How can I disable power to the STK convergence amps to see if my set will power up?

    Thanks,

    Dan

    I have this set also. The TV started having blue wavy lines across the top. Now the set will not power on.

I have one on my workbench right now please check the jumpers you unplugged especially the one on the far left corner (goes to front panel) the one behind the stk 392 010 you replaced (very easy to miss)
take good lighting and make sure every jumper is plugged in
skip this if your set was working but if it wasnt check the fuses and fusible resistors
third if all that fails check your soldering make sure the joints(on the stk's ) are all good and shiny and the joints on the heavier components especially the line output transformer the big black plastic thing on the right of the stk ic you could have loosened it [UNPLUG THE POWER CORD FIRST]

Tv won't turn on after repair


the first two things to check is to make sure none of the IC pins arent bridged with solder, and the other is to determine all wires are connected correctly and firmly.

Convergence issues


if youre having convergence issues with your samsung HC-P4752W you need to replace both convergence ICs numbers STK392-010 they are available at the following link and they provide free instalation instructions with pics so you can do the repair your self and they also give free tech support in case you need extra help. Its an easy repair takes about an hour from start to finish, Changing the convergence board wont help as the Convergence ICs are located on the sub deflection board and thats about 400 to replace the board compared to 50 to replace the ICs. Heres the link.

HC-P4752W - IC Replacement vs Convergence Module.


The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

Convergence Problem inSamsung HC-P4752W 47" Rear Projection


One of the convergence output IC's has burned out and needs to be replaced. If the IC opens up inside then it stops working without blowing any fuses or resistors. The IC should be replaced and the set realigned by someone with experience in convergence circuits.
