Question about RCA RT2350 System
It acts like it powers up then it powers off right after the power button is pressed i removed the second fuse on the main board and it turned on but will not put out sound when i put a new one back in it blows

I had the same problem! My fix was replacing both fuses and both 6800uf 16volt
capacitors. You can get the fuses at radio shack and I found the caps on ebay

This is an indication that the convergence amps are drawing too much current which has an effect on the power supply and thus killing your sound by removing or lowering the voltage supplied to that stage, finally this results in the blowing of the fuse. I would suggest that you change the convergence amplifiers and the biasing resistors (All of them) and then see if this corrects your problem (I believe it will). Also get a schematic of the TV and try to find out how the power supply relates the sound module and the convergence module, they might share a common power bus, or the voltage regulator for the sound also feeds the convergence board.
I hope this helps,

Based on your description, we can limit the fault to the power supply board and in particular to possibly 3~4 components:
As Jaime867 has suggested, in the absence of a readily available replacement board, component level might be the best alternative at the moment. Having posted the most likely culprits further narrows down your troubleshooting. Could you pls post back the part number of the smaller IC either 4 or 8 pins?
Alternately, pls check for the presence of a VDR, it would look like a coin (often green in color or something else) with 2 pins. They have been known to short out also and cause fuse to blow. One possible indicator is chipped or flaked of one side or a hairline crack on top. If it is chip, there would be a silvery color on the inside.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
