The first time I turn on my Samsung HLN5065WX/XAA each day it works fine. If I turn it off and then turn it on again without waiting a few hours, it tries to turn on three times and fails, and blinks all three lights (timer/lamp/temp). I have replaced the lamp and cleaned out the dust on the fans and boards, but still have the same problem. Any ideas on what to try next?

Thank you so much for the advice. I took apart my TV again and looked around. I'm not sure what exactly constitutes the power supply, but here is the board that the power cord was connected to:
![Electronics Passive circuit component Circuit component Electronic component Technology]()
![Electronics Inductor Passive circuit component Technology Circuit component]()
Nothing appeared to be wrong with the capicitors on it, what do you think?
Power then went to a board with some large heat sinks that was near the front of the TV, making it hard to see from the back. I was able to slide out another board that was in its way, but I couldn't get this board out. Do you know where the screws are that hold this board in. I would appreciate any help you could give me on removing this board so I could inspect/dust/replace it.
Finally power went to a board connected to the lamp, which I assume is the ballast. Here are some pictures of it:

Again, I don't see anything obviously wrong. This board does have a very large capicitor, and I assume that since my problem takes hours to go away it would probably be a problem with a large capacitor. Am I thinking correctly here? Would the ballast be the next logical thing to replace?
Thanks again for all your help :bigsmile:
