Hi, I saw an ad for BenQ LCD TVs that looked affordable considering their size and Full HD capability. What do you think? Are they worth it?

The cable guy doesn't know what its exactly called, and says its called a power stopper at the place where he buys it from, an electronics market.

Attaching a picture, sorry about the quality. though, there is an adapter between the insulator/power stopper to fix it to the old type hathway STB.

Edit- There is something like this that came with the set too. Its called an antenna isolator in the installation guide, to connect it to the RF input of TV or STB.

No problem. Glad I could be of help. Though, I forgot to add that the cable guy had to got a couple of insulators which differed in size. The small ones didn't work, this was the largest one.

This could be a signal attanuator which is used to attanuate extra signal level from cable line. Usually amplifier output is set at 100dB and TV/STB needs 60dB. Branching from main line for your TV, attanuates 10-20dB. Some sensitive equipment needs further decrease. That's why they are of diffrent types. [I was cable wala from 1990-2003]

Power Isolator - This contains two 102kpF/1KV blue colored capacitors in ground and signal path of cable input. This also looks similar as in picture. You can test continuity by using multimeter. Let me find one I will post picture of same. This isolate SMPS reverse static from 2-pin powered equipments.

In this case it may create some ground loop. So just try one thing, connect component+audio RCA cables between TV-STB such that only one ground connects towards TV. DO this with all equipments turned OFF and then turn ON after changes are done. It will break multiple path for ground loop. Let us know result.

Actually i thought ground loop is causing this issue and removed earth pin of my TV's 3-pin plug. Now its fine, but i need to ask my cable guy fix this by means of some insulators as suggested by gendarmee/you. But still my doubt is why this is not happening when it connected through RF and also its happening only if there is direct connection(high signal level?) to my STB from outside.

If ground loop is an issue, then while connecting through RF also i should face the issue and similarly if high signal level is a cause, then the issue should persist even after removing earth pin from the 3-pin plug of my TV,but??? :(

You answered it ourself. It is ground loop. "This is because your Cable TV's ground voltage is different relative to the house electrical system ground. This difference causes hum/noise in picture".
  1. If you remove isolator then STB is grounded through Cables ground.
  2. If you connect RF to TV then only one ground wire comes into use between TV & STB and that is of RF wire shiileded ground.
Now for components, multiple ground connection between TV - STB (R,G,B and audio L&R). Unless you remove earth ground difference in ground which persists or single ground path made between source and destination, hum appears.
  1. So either make sure only one ground connects TV-STB
  2. or there is no ground difference. (Which you are following currently)

Quick question everyone:

I had the Panasonic brand shop guys at home an hour back. Here is the deal details offered. I am quoting prices from another shop for comparisons:

42C10 Dealer Price : 44K , down payment 17K and 15 EMI of Rs 1833 ( processing fee of Rs 500)

42X10 dealer price : 49K , down payment 181875 and 15 EMI of Rs 2042 ( processing fee Rs 500)

Radhika Sales : 42C10 Rs 39.5K

question is why the difference in price from a company dealer and whether its a safe bet to go with another dealer? Both have a packed unit available and are ready to delivery it today evening.
To add to the confusion, I have given up on LG PQ70 since its not available anywhere. I have been waiting for almost a month and no dealer in the area has any clue about it. The LG local office had committed to get the PQ70 models in shop by 18th Feb but that hasnt happened. I wanted to go for PQ70 but have to go for the Panasonic C10 or X10 -- both above my budget

42C10 Rs 39.5K , looks good to me. Ask for 3 years warranty for this TV (Panasonic is already offering)

42X10 has additional HDMI input at side, apart from 2 at the rear. Otherwise, no difference between those models.

No idea about options in NCR, but 31K sounds like a good price of that TV. I bought it in Oct 09 for 33K.

Overall pretty good TV.

This means version of sales person always keep changing. As I heard that backlit LED more light passes through pixel so brightness is more as source is inline to sight. Disadvantage is that back light leaking is more. That's why they invented edge lit LCD TVs. Now they say previous was better?

IN my view LCD is LCD whatever it is.

^^ as far as i know - pixel illuminated LED LCDs are the best and can easily rival plasma in contrast ratios and blacks (individual pixels can be shut)
Edge-lit is as good as regular LCDs today and nowhere comparable to plasmas, just thinner!
Never heard of backlit LED LCDs
