Recently bought a 36" Toshiba Cinema Series (36AX61 I believe). On some stations there is a strong ghosting effect - it was very noticeable on ESPN or FOX football games. I had the cable company come out and they changed cables and the two way splitter located from the wall to the TV. Not much help.My next step was to make sure my cable run from the main feed was clean - that is, minimize splits, keep the cable away from electrical wires, and use plastic fasteners rather than metal "U" nails. Is this worthwhile or a waste of time? What should next steps be - call a Toshiba service man or get the cable company back out?
Thanks for any suggestions. This has been disappointing considering my expectations when switching from a 13 year old 25" Magnavox to a 36" supposedly good quality Toshiba Cinema Series.

Sorry, I didn't have a chance to work on this problem until this past weekend. I learned a few things (unless I was BS'd), but mainly I should have thought a bit before jumping into running new quad shielded cable, avoiding power lines, avoiding wall plates (by drilling through the floor), and upgrading to splitters that handle over 1000 Mhz. All these were supposed to help protect the digital cable signal I receive from Comcast, but I still had the problem.In hindsight, I should have carried my 19" TV out to the grounding box where the cable comes into the house and plug in there to check the picture! I didn't do this because I had a Comcast guy come out and he proclaimed the signal OK. Then I launched in to the above efforts with advice from the local Radio Shack manager, with whom I was impressed.
Exasperated, I had Comcast come back out and this time he declaired it was a main line problem somewhere in the neighborhood, but I was the only one to call in a complaint. So, they will start the troubleshooting this week. Oh well, I hope the investment in running new line, etc will payoff with an improved picture once it is resolved.
Thanks for the suggestions. I wanted to post this in case someone is faced with the same issue in the future.
This is what happened to me. My reception in my main tv room was very poor. My cable co came out and boosted the signal (internally), which improved the reception greatly. About a month later, they came out to upgrade my outside connections. After the upgrade, I had terrible ghosting due to a to strong signal. The cable co had to come out and remove the internal boosters. Problem solved. Just a thought.
have you tried connecting your old TV up and seeing if the ghosting is gone on those channels??? if the ghosting is gone, you may have a ground loop caused by the cable which may be more noticeable on some channels than others..... in such a case use a ground isolator for your cable ..... a really good one is from www.jensentransformers.com-Sam
From what I quickly saw, it seems to me these products are for cable only - I think his ghosting is inherent to Directv packing each transponder with too many channels (ie: compression). Although I'm assuming he is using Satelite vs. cable - I may be wrong.
hello
.
Hi,i use DirecTV also, and if you are refering to the cable from the receiver to the TV then the Isolation device will work fine! if you are refering to the cable from the Dish to the Receiver then the device will work for ground-loop, but WILL block the signal from the dish to the receiver....
If you are grounding your dish, then your ground-loop is probably coming from that! you can run the ground to the same outdoor ground used by your mains or you can purchase a device like the one below that will brek the loop, but not affect the signal!
great product meant for passing signal via glass, but will work pefectly to break a ground-loop induced by your dish!
