I am not a tv guy. I have no idea how to check the fans or the filters. I have changed the lamp and would be ok with doing the work if i knew how.
You mentioned a filter? Will the filter be visible at the time I remove the back cover? And I did see two fans were spinning freely... especially the large one on the left.
And finally, if after cleaning the unit and the fans (that appear to be working fine) do I need to be looking to replace the power supply? If that is the case do you think I can replace the power supply or should I take it to a tech at that point?
I did sign up for 30days unlimited promo - if I replace all the fans and the problem does not go away, is the power supply the problem. If the power supply is then the problem is that something I can replace?
Once I open the back panel will I see all the fans and the power supply?
