Question about Philips Magnavox 51MP392H Rear Projection Television
I took the screen and the furencil off yesterday to clean the lenses then i found that if you look in the blue and green lenses that they looked like they had saw dust in them. how could that be? because i took 2 of the 4 bolts that holds the crt to the lenses on the red one that a clear liquid came out so obiviously it is liquid cooled. well after a little came out i tightened them back up. so i was still puzzled. then i wiped the chip boards down and put everything back together and we watched t.v all last night til about 2:30 in the morning. well i just turned on the t.v and i have no pictue. i took the screen off again and looked in the lenses and i couldn't see no picture. but as you change the channel you can see the time and channel number but no picture. and the fuses underneath the crts don't look blowin so what can i do? can you please help me with my questions. thank you for your time
I will say that you probably still have the clear liquid (Glycol) still on the board. I recommend cleaning with a degreaser spray and brush it off with a clean 1inch paint brush. You can get the spray at Radio Shack The glycol is hard to remove and is conductive to electricity.
