Questions & Answers about Sin garantía, el arreglo del televisor sale caro.

Why does sin garantía come first, and what does the comma do?

Sin garantía is a fronted prepositional phrase that sets the condition/context for the whole statement: in the case where there’s no warranty.
The comma signals a pause and helps the reader hear it as an introductory phrase. In everyday writing you might also see it without the comma, especially if the phrase is short: Sin garantía el arreglo del televisor sale caro.

Does sin garantía mean “without a warranty” or “without the warranty”?

In Spanish, sin + noun often omits an article and is understood generically: sin garantía = without warranty coverage (in general / in this situation).
If you want to be more specific (e.g., without the warranty that came with it), you can say sin la garantía.

Why is it el arreglo and not a verb like arreglar?

Here el arreglo is a noun meaning the repair / the fixing. Spanish often uses a noun phrase where English might use a gerund or infinitive.
A very common alternative is the infinitive construction:

• Sin garantía, arreglar el televisor sale caro.
  Both are natural; the original sounds a bit more “noun-y”/matter-of-fact.

Does arreglo definitely mean “repair” here? I thought it could mean “arrangement.”

Yes—context makes it clear. Arreglo can mean arrangement (e.g., un arreglo floral = a flower arrangement), but with something broken like a TV, el arreglo is understood as the repair.
If you want a less ambiguous word, la reparación is also common: la reparación del televisor.

Why is it del televisor and not de el televisor?

Del is the mandatory contraction of de + el:

• de el → del
  So el arreglo del televisor = the TV’s repair / the repair of the TV.

Why do we say televisor (masculine) and not televisión?

In much of Latin America, televisor is very common for the physical device (the TV set). Televisión can mean the medium/service (television), and sometimes also the device depending on region.
Both exist; televisor keeps it clearly about the appliance being repaired.

What does sale caro mean grammatically? Why sale?

Salir has an idiomatic use meaning to come out to / to end up costing. So sale caro is like “it comes out expensive” / “it ends up being expensive.”
Grammatically, sale is 3rd-person singular because the subject is singular: el arreglo.

Why not just say es caro instead of sale caro?

Es caro describes something as inherently expensive (a general quality).
Sale caro focuses on the result/total cost once you do it—often implying you might not expect it, but that’s how it turns out. For repairs, sale caro is very natural.

What exactly is the subject of the sentence?

The subject is el arreglo del televisor.
Sin garantía is just an introductory phrase giving the condition; it isn’t the subject.

Why is caro masculine singular?

Caro agrees with what is “expensive” here: el arreglo (masculine singular).
If the subject were feminine, it would change: La reparación sale cara.

Could I move sin garantía to the end?

Yes, and it’s still natural:

• El arreglo del televisor sale caro sin garantía.
  Fronting it (Sin garantía, ...) emphasizes the condition more strongly.

Is there any nuance between sin garantía and fuera de garantía?

Yes:

• sin garantía = without warranty coverage (maybe it never had one, maybe you don’t have it, maybe it’s not covered).
• fuera de garantía = out of warranty (expired warranty period).
  If you mean “the warranty expired,” fuera de garantía is often the clearest.
