Re: Can't find out what the rating of this cap is
ok thanks. I found two 35v 1000uf from another power board i had. I am also checking the diodes in the tv because the tv will turn on but no picture or sound. I checked the power on the power board and it will power up the 12v line and then after like 4 seconds will drop it then charge it and then drop it again. I checked the voltage on one of the resistors that was for the AC side and it would go up to 120v then drop to 65 volts then go back up to 120v. so im not sure what component it might be causeing that i was wondering if it was the square transformer with the two coil windings that you can see cause i think its making a humming noise when it has full power then the humming goes away when it drops voltage. Any insight? Also when I was checking the diodes i would hook up my dmm one way idont remember which side red was hooked up to anode or cathode but it would go up to like .278 on diode check and then if i reversed it it would show .238 and start climbing. A few of them did this and then i checked another and one way it read .378 and then the other way read OL. does that mean its no good?

Re: Can't find out what the rating of this cap is
C841 is a common fault on this model (red poly cap centre of board), I would suggest replacing it too.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
