I own an LG 42 inch LED TV. Using it with a Videocon HD D2H. What stabilizer should I use? Would the V-Guard Mini Crystal suffice for daily use?
 
Have you measured voltage range of supply at your place. Buy the one which gives higher range of protection if in case there is an issue or under voltage or over voltage. I have used this product and its good.
 
Voltmeters are less expensive I think. And with no attitude issues.

Jokes apart, Wouldn't Crystal Plus just do the job?I live in Bangalore and there are no fluctuations here in Voltage. Only power loss some times.
 
I dont know. You tell me. what's the difference. Isn't UPS for backup when the power is down while the Stabilizer saves your electronic device during power fluctuations? I dont think I need a UPs in this case.
 
I'm not sure, that was my guess. But my idea was that UPS have better power control logic and will be better in these situation. That is also why we use them with PCs. May be someone here have better explanations...
 
Just check your voltage(simply purchase a multi-meter, which is around 150-200 rupees). Check at different times, i mean in peak hours,midnight,afternoon etc....If its giving voltage in a good range no need.
Instead of Stabilizer you can go for a UPS, it also give surge protection. Now a days Electrical meter are also digital in Bangalore, so check the voltage there, it should not cross 250V. At the same time check your ground voltage also.

If UPS is better than Stabilizer, always go for a UPS; the price difference should be minimal. Whichever the city is, Indian conditions require electronics devices to be protected.
 
I used to use a UPS with busted battery for my LCD TV. logic being that I wont have to spend money on the stabilizer as I had UPS lying around. and Usually UPS will have a better circuit protection where instead of trying to stabilize the current, they simply cut off. and in case of low voltages they wont turn on.

stabilizing voltages requires big ass coil hence the cost of stabilizer, in UPS everything is controlled by mosfets. I think...:bag:

LG website claims that I dont need a stabilizer for the LG 42LB5610 that I own. I talked to the guy at Croma and told him I use a Belkin power stripsurge protector. He said that it should be enough and I can claim for damages from Belkin if somethings happens to the TV.

The conventional offline UPSs are not voltage stabilizers, nor are they better. The only voltage stabilizing they do is switching to battery backup if the voltage is outside a pre-set range. To avoid switching to battery backup too often and shortening the battery life, this range is usually set pretty wide, like 180 - 260V. Only online UPSs continuously convert AC to DC to AC and keep the output steady at 230V. They are not cheap - the SmartUPS range is the online type I think and prices for those start above 10k.
Electronics these days (like LCD TVs) run off lower DC voltages and use an SMPS (similar to the one we use in PCs) to convert AC to DC, and these have a wide input voltage range (IINM mainly so they can function in both 110V and 230V supply countries), so you should still be ok.

However lightning/surge protectors are sacrificial, i.e. they protect other components by absorbing all the energy themselves, and getting damaged in the process. The varistor mentioned in the LG brochure above is one type. Think of it as a one time fuse. So you're better off keeping it external to the TV because it's cheaper to throw away a surge protector than to open up the TV and replace this component, or worse assume its still functioning and not have it protect your TV the next time there's a surge. This is another flaw with surge protectors because most of them do not indicate if the varistor is still functional.

UPS is required for purposes where a safe shutdown to protect the system state is required. This is not needed for TVs.

A 2 layer protection - fused power socket + V-Guard will be much more than adequate.
