Hi:
You need to have the solder connections on the vertical output IC. Also there is pump up capacitor that goes bad or leaky that need to be checked. Rework the entire vertical section of the set to make sure all solder connections are ok.

Both of those resistors are 3.9 ohm 2watt metal film resistors for the convergence ICs. The ICs will most likely need replacement as well.

this is likely a convergence problem, the convergence chips- stk-xxx-xxx would need replacement
along with the large wattage resistors connected to them-look for 1-3 ohms the exact value varies
over a number of models do an ohms check replace if out even a small amount

Hi,

There could be many reasons for the same ranging from convergence problem to faulty hyper module. This problem needs a tech to properly diagnose the board and the module. It would be worth repair. Do not try to get it repaired from a local shop as i have seen them overcharging for small parts.The best option would be to call Samsung and get it replaced.The repair would be anywhere around $250 - $350 depending upon the fault.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Your problem is do to shorted Convergence Ic's which will not let the set power up until problem is rectified. You have a very reliable set there. The Ic's will cost about $25.00 for the pair and a tech can install them reasonably cheap. I do recommend repairing it.

Hi,
Problem seems with convergence output section and there would be dry solder connections in convergence output section.
Re-soldering convergence output chips pins will be helpful to solve this issue.
If you have no experience of soldering work in tv circuit board then local tv repairman will help you.
Let me know if you have additional question.
Thanks.

You probably need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

In my case it seems that the board to the left is causing the problem ,

not detachable daughter board thet accepts the inputs or the center board with the flyback xfmr on it .

You have a bad convergence board. Replace two of the STK 392-040 ICs. And check all the resistors that are next to these ICs. Rplace the resistors as neccessary. This will repair your TV. Thanks for asking...sorry it took so long to find you!

Most likely what happened is that the lamp in your TV shattered and is going to need replacing.

Maybe theres a defect in switching botton,or your fuse is worn out so it cannot on the power , just check them all.
