Digital Cable Problems

Digital cable offers plenty of options to viewers in terms of more channels, on demand programming and crisper audio and video. However, you may have come across a few problems such as bad reception, poor picture quality, and interference when using a digital cable tuners or digital cable boxes. While some of these issues or digital cable problems can be fixed on your own, others may require the help of a professional. Listed below are a few questions answered by the Experts on issues related to digital cable problems.

Why is it that whenmy digital cable box is attached to a 32” Polaroid HDTV and is the cable is turned on, after 15 minutes the power finally comes on?

The problem you have stated above is one that has been found on many LCD and Polaroid LCD TVs. It usually indicates an issue with the power supply caused by electrolytic capacitors that have been worn out over time. If this is left untreated, the problem just gets worse till you reach a stage where the TV doesn’t come on at all. However, this can be fixed by replacing all the bad electrolytic capacitors on the power supply board. A TV repair shop should be able to do this for around $150 to $200.

I have hooked up my Sony Bravia to a digital cable box via an HDMI cable. But the pictures and sound are fractured across channels. What do I do?

The first step that you can take is to change the HDMI cable as this could be the cause of the fractured images. If this doesn’t work, it could indicate that either you have a faulty HDMI input on the TV or that the digital cable box is faulty. Get the cable company to switch your cable box to diagnose the problem correctly.

I had vertical lines across my 52” Samsung TV and the technician who came and looked at my TV said that the digital cable board needed to be changed the problem is still not solved after replacing the digital cable board, what could be causing this?

Unless you test the circuitry of the TV, you can’t be sure of how to repair it. It can be expensive to replace parts if you have not correctly diagnosed the problem and can also lead to new parts getting damaged. You may need other outside Expert help to troubleshoot the underlying issues.

My Zenith model L23W36 is connected to a Comcast digital cable and when I switched it on, it displayed a snowy picture. Changing the channel with a remote didn’t change anything and when I used the TV buttons, the display showed a "Key Lock" message. Now I can’t turn it off despite trying with the remote and the On/Off function. What should I do?

The most important thing to note here is that the On/Off button is not responding. This typically happens when the microprocessors fail. At this point, you can switch the TV on but it can’t be turned off and needs to be unplugged to switch off. The key lock problem and the fact that you can’t change channels are also controlled by the TV’s microprocessor.

However, you could try and unplug the power cord of the TV for an hour, plug it back in and see if it works. Occasionally what happens is that the microprocessor gets scrambled. When this happens, you need to bleed off the power and let it reset properly before it begins to reload software and and operate properly. This may sort the problem out if the microprocessor has not been completely switched off prior to this and the system is operating with scrambled software. While you may have come across some of the problems mentioned above, there could be other issues that are related to your own unique digital cable box. For example, if you have used extra long cables and there are several cable splitters that divide the incoming signal you could receive poor picture quality. Or you could experience interference as a result of placing an electrical device too close to the television. Whatever your problem, direct it to a TV technician or Expert who can help you find a sensible way to tackle the issue that is both quick and cost-effective.

  • Re: Model #RTD317M, Serial # ***** Folks: This

    Re: Model #RTD317M, Serial # *****
    Folks: This unit came installed in my new Brookstone (made by Forest River) Fifth Wheel trailer that I bought in March, 2011. Until today, I have used the unit only for listening to Sirius Radio, using the "Aux 1 In" feature. Today I finally hooked it up to my TV set so I could watch DVDs with great sound. Everything looked OK until I inserted a DVD. The tray won't stay closed. After a few seconds, it just reopens. I've tried it with several discs and the same thing happens. Am I doing something wrong? Am I not doing something I should be doing? Please advise. Thanks.
