Question about Samsung HCL4715W 47" Rear Projection Television
Posted by Anonymous on
I was just working on replacing my stk's and was wondering if you could tell me what value the resistors are? Here is my previous post if you would like to see it. http://www.fixya.com/support/t191186-blue_out

Usually if some parts on the board burnt on that model it can be caused by leaky tubes. Meaning the coolant from the crt's has dripped out. If burnt components are beneath any of the tubes, inspect very closely for liquid substance having leaked down from coolant chambers above. If this has happened you must seal leaky gaskets before going through any trouble of pcb repair.If burnt parts are not below tubes, most common cause is bad convergence ic's. At any rate, service info avail online or at samsung.com or 1800samsung. Hope this helps.

Hi again and welcome back to FixYa,
Appreciate the direct "Ask Me'.
Based on your original post, only the STK ICs were replaced. Presumably 392-040, the surrounding resistors and pico fuses could very well have been affected as well. Depending on the board revision (pls confirm location numbering on the actual board), the resistors could be:
RZ104 -RZ106 - 270 Ohm 1/2watt
RZ133-RZ135 - 27K Ohm 1/16 watt
RZ136 & RZ138 - 3.3K Ohm 1/8 watt
RZ146 and RZ147 - 3.9 Ohm 2 watt
RZ148 and RZ149 - 150 Ohm 2 watt
while the pico fuses would look like the image below.
Good luck and Thank you for using FixYa.
