The trouble ive found doing this is a lot of boards may use slightly smaller capacitors under heat sinks etc some diameters also varies on boards where capacitors are close together. Im not sure if there is a list of common volts uf height diameter capacitors you can use maybe budm or tom or someone who repairs sets very regular has a list they use to order.

Re: sceptre x420bv-f120 lcd tv wont power on

i always buy 35 or 50 volt and modify mounting when needed.....

bud ..vnce....can using the 47uf to replace 33uf during short term testing have any negative effects on board?

Great, yes bad cap can look normal so you need ESR meter to verify them.
