Question about Samsung HCM4215W 42" Rear Projection Television
Press power botton power light flashes a few times then nothing
replaced the red PCB and converg board with NEW parts, TV turned on for a min, long enough for me to start the perfect focus deal. went to 4% and got stuck, so i turned off the TV . turned it back on and now the light flashes but nothing happens. when you normally turn on the set it clicks,, well theres no click now and no little tones from the speakers , but you can hear something actually charge (for lack of the actual term) then nothing , if you unplug it and hit the power button it goes BEWWET.. then its silent once again.
i was really hoping to just replace the STK board and red PCB that caused all the problems to start with, and was pleased that it didnt explode when i was done installing the new parts , but now i need help with this new issue.
Check the convergance board for open pico fuses located near the stk amps if they are open the you may have a yolk problem as well. also check the blue gum for cloudy fluid this may be the reason the perfect focus got stuck. if you should get the tv to fire up go to the menu then select reset factory in the convergance menu of the customer menu. this will pull the convegance back to tollorance. the trouble is that when the convegance amps fail customers tend to perfect focus the set and each time they do the convegance memory goes further from tollorance. thus failing the ICs once again. check the pico fuses 1st this is a tell tail sign of those two conditions (yolk, or out of tollorance).
