Answer
The number of blinks on the standby and/or power LED is a code that indicates what the general problem with the TV is. Generally speaking, though, even if you knew what the codes were, these aren't the kinds of problems that a consumer can correct. You have to have a TV repair technician look at it and troubleshoot the problem.

VIZIO LED TV cable signal problems?




Pat


We have owned a VIZIO 55" LED TV (model M550SV) with no problems for almost a year now. The day before yesterday, the cable TV (which is connected via coaxial cable through a cable box) suddenly stopped working while we were watching it. For the last two days, I have beat my head against the wall trying to fix this.

This is what we have done so far:

- Tested the cable box on a different TV. It works.
- Scanned for TV, Antenna, Digital, Analog channels. Nothing.
- Reset TV to factory defaults. No change.
- Changed every cable going from the wall to the cable box to the TV. Tested again.
- Everything suggested in the user manual under troubleshooting. Nothing.
- E-mailed customer technical support. No reply.
- Called technical support. Telephone number goes to a phone tree with no option for support.

I am about at my wit's end. I'm very technically savvy and have NEVER had such a problem for such a length of time. This is the first time I've not been able to fix something myself.

I am hoping someone out there has had similar problems and can save me some time and aggravation by telling me what the problem actually is. Please help!
We did try a separate TV on the same setup and it worked fine. Similarly, anything running into the TV via HDMI, Comp or through wireless internet works fine, too. Unfortunately, the cable setup is coax only.

I'm fairly convinced it's a TV hardware problem. Believe me, I'm going to raise hell until Vizio makes this right (especially while it's under warranty.) Thanks for the answers, everyone. It was eye-opening.



Answer
Analyzing with the info you supplied.......

1. "...the cable TV (which is connected via coaxial cable through a cable box) suddenly stopped working... [and] "...Tested the cable box on a different TV. It works...." Therefore, your cable system is okay from the wall outlet and through the box. Whatever your problem is, it's not a cable problem.

2. ".....Scanned for TV, Antenna, Digital, Analog channels. Nothing....." Are we to assume that you do have a good antenna and that you previously received over-the-air channels with it okay? If you didn't, this is not a valid test.

3. Aside from the antenna test, have you tried another known good source with the TV, connected on a different input than the cable box? DVD player? VCR? Game box? The point here is to make valid tests with alternate sources to try to narrow down the culprit to a particular input or circuit on the TV.

4. "...We have owned a VIZIO 55" LED TV (model M550SV) with no problems for almost a year now...." That suggests that the set is still under its factory warranty. If you don't find a quick and practical fix from my or any other suggestions, start the warranty repair process.

On the phone tree frustration, if you don't hear an option for tech support, then pick another one until you get a human, regardless of the department. I've had to do that on occasion and was finally transferred to a customer service rep.
======================
Per your Additional Details: "....Unfortunately, the cable setup is coax only...." Given that the HDMI connections to your TV are okay, the fact that you are not connecting the cable box to the TV the same way, and can only do it via coax, suggests that it's a simple digital-to-analog converter, like the Comcast DTA -- the only output is analog on coax.

So, these questions arise:

1. Which output channel is your DTA (or whatever) optioned for: Ch. 3? Ch. 4?
2. When watching cable, do you set the TV's input to the tuner?
3. Do you select the channel that matches the cable box's output (3 or 4)?
4. Have you tried testing your tuner with another source? In your case, a VCR would be ideal?

Since I've only guessed above that you are using a DTA or similar, in the event you have a conventional cable box with the usual multiple outputs, why are you connecting to the TV with coax? The preferred choices would be, in order, HDMI - component - composite - coax.
