Good point, but to elaborate...
When a radio comes in, and has "no output"
What is one of the first things you SHOULD do?
Answered in post #18...
Lift the legs of the power amplifiers and clean underneath them - e.g - clean and verify your work is not causing this condition.
That step is almost a requirement with Silver soldering (Pb-Free) these days - ranks right up there as a Requirement like 10+ year old radios recapping.
The rest of the mess was answered by Voltage readings, changes and operation.
No power? But seemed to operate as expected...
Bad parts blown shorted, usually pulls down the power thru excessive current draw, Radio goes Dim.
... or ...
Blown open parts keeps power too high because there's nothing there to draw it in and use it - no power flow. Radio just sits there and idles.
That is the Why I asked about voltages - no sag, little power - hardly any current draw - open parts or open lines to the parts that would take power and pull down those voltages you need to set for, would show voltage variances (none to little voltage drop) while bad soldering, or shorted parts would show up has heating, or very strong power draw and still low voltages.
So - open - or blown parts leaves higher idle voltages and little power draw
Shorted parts lower expected voltages thru higher current demands dimming displays...
Either way, low or little to no power out...
A short between two stages to ground (blown cap to ground) gives the same thing - both sides just sit there waiting to work - produce a signal. But, one side would produce power - pulling voltages down thru the short until it failed.
So since he had it working to a degree - variable worked - voltages seemed high but not excessive - best to review what was done, do the best you can to clean up the work - then try again.
Remove all doubt...
