@edgarblythe,
If that's the case (lack of $$$), I'd call a good TV electronics repair place and see if they would give you and idea of the cost, but typically they charge anywhere from $50-$95 for diagnosis which would apply for towards the bill if you said yes to repair.
Personally, if I thought the repair place was not an option, I'd look at the used market on Craigslist classified ads. You can find a decent one for $250-300 instead of say a $500-$700.
If that's something that sounds plausible, let me offer you my assistance in selecting a potential worthwhile one...just private message me and I'll help however I can. I'm pretty knowledgable about stereos and home theater etc.
