Question about Samsung HLP4663W 46" Rear Projection HDTV
How can i check whether the ballast on my hlp4663w is good or not? i need a new lamp for sure, but i suspect the ballast is bad too. can a bad ballast damage the new lamp (i don't want to buy a new ballast without knowing it is bad for sure)?
The transformer can't damage the new lamp. Faulty transformers normaly take out the driving transistors or the fusible link in the power supply, if these are good then just replace the lamp. Espacially if you know the lamp is bad (test it by swapping with the others if unsure)
