Check the IC numbers used in it kit; and distinguish which company kit is used with. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
They ain't diodes because "R" stands for resistor! If you look at them they should have a bands of colour on them. If they are burnt or black they will have failed. Which means you will have to find out what value they are before you can replace them. If the coloured bands are present you can search on-line for a resistor colour code chart. They often have four bands. The last one (4) will be most likely be gold. Bands 1 & 2 are numbers and band 3 is the decimal point place. The Ohm meter might tell you the value, but it will be affected by them being in circuit.
You can try replacing the resistors. They are available using part number: ERDS1FJ100 from tritronicsinc.com for $1.10 each. Typically though, the reason for the silence is a defective output amp-pac. This too can be purchased from tritronicsinc.com using part number: RSN3305-P for $65.73. This is the amp for the front speakers. The rear and center speaker5s use part number: SVI3205B which is listed as no longer available.
