3.LG 42ld460 kaso takot ako ab0ut backlight bleeding issue

4.SANYO 42 INCHES worth 35k yata yun full hd din cya
which this 4 ang mas ok and madami cons
I have seen and evaluated these models and these are my initial findings:
TCL 40F10, Toshiba 40AV700 and Sanyo 42K40 are using S-PVA (VA) LCD panels. The LG 42LD460 has IPS LCD panel. Through the TOUCH and PRESS the screen method that I do, I can only tell if a panel is TN (Twisted Nematic), VA (Vertical Alignment) or IPS (In-Plane Switching), but can't particularly differentiate from their variations (MVA, SPVA, S-IPS, etc.). Ang TN ang pinakamahinang type of LCD panel na ginagamit kadalasan sa mga PC monitors kasi cheap to build. Ang IPS naman ang pinakamaganda kaso mahal. The VA type naman ay in between sa dalawa and this is widely used by most brands (SONY, Sanyo, Samsung, Sharp, etc.) but implementing the most superior SPVA variation.
All models are with CCFL (Cold Cathode Fluorescent Lamp) backlights. For me and based on years of observation, the CCFL backlight is far superior to the LED backlights. The WHITE is WARM for the CCFL, while BLUISH WHITE ang sa LED backlights. Ang mga CRT (Cathode Ray Tube) at Plasma ay may WARM WHITE pag dating sa WHITE BALANCE.
Ang AGING ng CCFL ay gradual at lakas lang ng BRIGHTNESS ng backlight ang affected. Sa LED backlit TVs, abrupt ang AGING at affected both ang BRIGHTNESS and WHITE BALANCE (the screen becomes even MORE BLUISH resulting to impaired PQ). Paulit-ulit ko na ho na witness ito all those years from all brands using LED backlight.
Con sa CCFL na LCD TVs, they consume more power compared sa Edge lit LED backlit LCD TVs by approximately 40%.
The four models ho na type nyo are all 60 Hertz refresh rate. For me maganda at preferred ko ang native 60 Hertz na mura pa compared sa mga 120 Hz or 240 Hz models. Take it from the experts here and abroad, the 60 Hz native refresh rate ang preferred nila. Read the articles/reviews of Dr.Raymond Soneira of Displaymate, David Katzmaier of CNET, and others and you will be surprised how we ordinary users misinterpret the TV's specifications lalo sa CONTRAST, 120/240 Hz, judder, etc.
The Toshiba has somewhat grainy or noisy video reproduction. Probably because it has a wider video bandwidth circuitry to make the cable reception similar to the plasma and CRT TVs (Plasma and CRT TVs have grainy video signal) for SD clarity. Ang Toshiba ang may pinakamagandang TV/SD reproduction. At proper viewing distance, like the plasmas and CRTs, unnoticeable na ho ang noisy or grainy screen at very sharp nga ang antenna/cable signal.
Ang Sanyo at TCL maganda rin. Ang hindi ko lang maunawaan why the TCL big screens do not employ the better IPS panel they used for the 19-24 inches models.
When it comes to RELIABILTY (durability), mahirap masabi maliban na lang we rely on the forums. Pag kasi ho may nasira na TV from a certain brand hindi naman pwede na we immediately conclude na sirain nga. We need exact percentage kung ilan ang failure rate kaso this is very hard since RELIABILTY is time dependent para mapatunayan. So in this case, I will go for the LG because of its renowned after sales support lalo na ang tungkol sa mga feedback na even after the warranty period LG still gives 100% free service (AMAZING !!!!!). Experience ko sa servicing, SAKIT sa ulo ang mga vendors pag tapos na ang warranty period (dapat samahan nila ng sang dosenang paracetamol ang box ng TV).
The other +/- factors are already discussed in some forums/posts kaya no need to mention.
For me, this is my choice :
LG 42LD460 > Toshiba 40AV700 > Sanyo 42K40 / TCL 40F10
