Can't find out what the rating of this cap is

[audiofreak19]

So I got a free proscan tv and it has two buldged caps but I can't look up the rating. Only thing written on it is cd288h(m). Any insight is appreciated

Can you post a picture of the capacitors and the location on the board? This can give us a good idea of the value you will need

Did you look on the other side of the caps? You might need to remove them to see their value. They're most likely 1000uF 16V, or 680uF 35V, or one of each

You will need to remove them to see other side, it will be printed on them.

Lol wow I had a blonde moment. I was looking all around the cap while it was on the board and didn't see it. Took it off and it clearly says next to the ground strip 100uf 35v. Lol thanks guys

Of course the only cap I don't have. Do u think I could use a 100uf 25v

Re: Can't find out what the rating of this cap is

It probably has ~24V going through it, so it would probably work fine but it would be pushing the capacitor to the limit and might not last too long. Are you sure it's 100uF 35V? It looks huge for that value

Re: Can't find out what the rating of this cap is

Its a 1000uf 35v

Sorry for my typing

Re: Can't find out what the rating of this cap is

If you have a 1000uf 50v It will work. Using a lower V rating when replacing a capacitor is asking for problems.

Re: Can't find out what the rating of this cap is

That's what I was thinking but wanted to make sure. I will see if I have something I can harvest from another board lying around

Re: Can't find out what the rating of this cap is

1000uF 50V is probably too large for that area. I know it sucks but it's always better to order the proper parts so that you don't have to do the repair again.

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

diodes im not sure of i just lift one side clear of the board and retest them.

Re: Can't find out what the rating of this cap is

Can we get good clear pictures of the top and bottom side of the board and model number of the TV?

[audiofreak19]

Re: Can't find out what the rating of this cap is

yea i will get the picts of it tonight and the model number.

[audiofreak19]

Re: Can't find out what the rating of this cap is

Here is a pict of the power board. The model number of the tv is 42LC55s240v87

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.
