No Useable Signal

[Nuke]

I've got this 10 year old RCA TV f19426 that I had hooked directly to my cable connection (no box) that not tells me "no useble signal". Other tvs work fine on it. Is the tv no good anymore? Recently had a big outtage here. Maybe surge fried it.

have you tried reprogramming the channels (auto-search). Also, make sure it is on the proper input.
During setup, if it asks if you have a cable box or VCR, tell it no, otherwise it will lock on to channel 3 and appear to be stuck.
What Chassis # is it?

Are the sets that are working newer models that can decode digital QAM signals on the cable? Perhaps the cable provider has recently switched from analog to digital, and the 10 year old RCA can't decode the QAM signals.

Try hooking up a VCR or a DvD player to the set using the RCA jacks. I won a new RCA F27628 at a Christmas party through work one year. Had the set 2 weeks and had the same problem you had. The antenna/cable connection went out on me. Since I had won the set and had no clue where to return it nor did I have a reciept, I couldn't return the set. So I've been using the rca jacks and a VCR ever since. A shame too since this set has the built-in program guide that I can't use. And after 13 years it still has one of the best pictures of any tv I've ever owned.

I've been following this thread with much interest. However, I wonder what all this talk about something called "Q A M" is? There is a radio station in Miami with those call letters (all sports, 560 kHz), but I'm sure no one is getting an AM sports station in Miami on a TV that may be a thousand miles from that city. Maybe it's WQAM-TV?

QAM is the digital modulation method for cable TV, while ATSC is used used for over the air digital TV.

QAM stands for quadrature amplitude modulation, the format by which digital cable channels are encoded and transmitted via cable television providers. QAM tuners can be likened to the cable equivalent of an ATSC tuner which is required to receive over-the-air (OTA) digital channels broadcast by local television stations; many new cable-ready digital televisions support both of these standards. Although QAM uses the same 6 MHz bandwidth as ATSC, it carries about twice the data (38.47 Mbit/s @256QAM per 6 MHz channel) due to the lack of error correction; however, this requires a significantly cleaner signal path, such as distribution through hybrid fiber-coax digital cable.
