I just acquired this TV and the TV powers up has sound but no picture, looked inside all four green LED's are on and the one red led...not sure what is causing the problem. the red, blue and green bulbs have no glow to them at all...

thanks for any help

Pictures?

That's good sign. Look for orange glow in each gun assembly near the CRT socket in each CRT. If so, you have horizontal sweep running.

Deflection problem (the same board that has 4 green and one red LED glowing, this is power/deflection board) troubleshoot there.

Got scope and multimeter?
