2 Answers

Hello, After I've changed the stk's on a rear projection SAMSUNG TANTUS 42" it worked fine for a couple of weeks, then started to had a convergence issue during the first 1 or two minutes after turned on. Now it simply won't turn on jus makes a constant funny noise. It could be a wrong stk's model? thanks

    Thanx curtis, I´am not familiar with tv´s and to be honest I don´t know what do you mean with "the lamp" I can do a little more research but I still appreciate your guiding here.

    Best Regards and thank you very much.

    well, the new STK´s i´ve just installed are 392-040. I will check those resistors then the stk´s.

That noise is the lamp trying to turn on but it is probally burnt out so you may need to replace the lamp.

You could have STK IC that is defective causing problem, Set will shut down if you have Bad IC.

    This Model does not have a Lamp , it is projection that has 3 Tubes Red/Green/Blue.
    You have installed the correct ICs, So Where are you at Now? I have 3 pages of problems and solutions for the Fix in my Index Manual.

you need to general service the whole unit. this will include re-soldering and changing some defective components from the board, which has been damaged through using from past years. my advice is to have a quotation from service tech and then think about repairing it..if it is better to buy a new one..

My hcp4752 started smelling hot now the colors are


It looks like you have a problem on your convergence panel. Look for burned resistors near the STK-* IC's. One or more of the STK-* IC's may be bad. When the resistors get hot they smell but so do the IC's. You can replace the bad parts or you should be able to replace the entire panel then go thru a convergence alignment.
