You most likely have some resistors that are needing to be replaced its not uncommon for Samsungs ICs to open a couple resistors when the ICs go out and installing new ICs with the old ones being open can cause more of the convergence resistors to burn. Post the model number of you set and I can let you know which resistors you likely need to replace.

Convergence problem


The convergence board is bad in this set. Samsung no longer has this board in stock. You will have to take the board out and rebuild it by replacing both of the STK convergence amp IC's These IC's are soldered to the printed circuit board. They will be standing up against a metal plate, called a heat sink. They are black in color and are about 2" by 3" . They have white lettering on them that start with STK and the some numbers. You get those numbers and go to mcmelectronics.com, enter the exact number of the IC and order two of them. Before you install the new IC's you will need to apply some heat sink compound onm the back of the new IC's. This heat sink compound is avaialable thruogh radio shack. Good Luck

You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

Likely to be the convergence power supply module. If you fix yourself it is simple provided you can get the module. Take the back off AFTER unplugging set The module is located above the main board on the left and the dynamic convergence board on the right. and come out by about 4 quarter inch nutdriver screws and has only two plugs one on each end of the module. You may find a good used one at your local tv shop or get them to order a new one or fix the existing module by changing the chip on it where the metal heat sink is. Chip number is STK 730-010 or STK 730-130. Either will work. Chip will usually fix it. If not the entire module must be replaced

HCM4215W Green convergence problem


Hi Greg,
Sounds like you have a bad convergence chip in the convergence board. Unfortunatly, about 80% of the rear projection sets I work on have this similar problem. I suggest that you change both chips ( there are 2 of the same ) and remember to use heat sink compound as this is why you not have the problem ( excessive heat destoys electronic components). Good Luck
