Question about Westinghouse TX-47F430S 47 in. LCD TV

1 Answer

So we got our LCD panel replaced as there was some banding going on. With that said, I'm wondering if the Panel itself can cause the picture quality to drop. I'm seeing a much more pixelated picture (very grainy). Could this be due to the replacement lcd?

Yes it could be an "Inferior" one indeed.. However check all your resolution & settings on your TV.

The screen is showing green all over the images on the tV


This may be caused when your picture tube is magnetized and it should be demagnetized to return back to normal.
As a simple measure, switch off the television and UNPLUG IT FOR TWO TO THREE HOURS AT LEAST. The longer the better. Then switch it back on and see if it get demagnetized all by itself. This is just a try.
If it fails, try replacing your picture tube. Try to have undamaged picture tubes of old color televisions as they are of better quality than modern ones.

Hello,

 

Picture quality problems (such as lines, fuzzy image, or wrong colors)

  1. Check the cables and connections: Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
  2. Check the  display issue with  a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal. For example: if the image quality issues occur while viewing TV , switch the source to a DVD player to see if the image quality problems go away. If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and . If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Try to Reset the TV ( LCD) quality options. Please look in to User Guide to make the TV to factory Defaults..
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV . If the image quality problems still exists across all types of signal sources, the TV should be serviced.

I hope that this should resolve the issue. However, if the issue still persists then please contact LCD manufacturer for further more on the issue.

 

Bye.

My Westy 47 TV has a very strange power-up problem! First, I found that the power supply was bad, I couldn't repair it, so I bought a replacement from ShopJimmy. The replacement seems to be working fine, and sometimes the TV works fine. The little green LED near the bottom edge of the controller board lights up when you connect the AC power, as it should. There is also a small green LED near the upper edge of the controller board that apparently lights only up when the controller is working properly. I've replaced the 470 mFd, 16 V. 'Lytic on the controller board, as everyone says to do. I still observed about 0.8 Vp-p of digital signals on the 5 Volt buss with the replacement capacitor these signals looked kind of like a 300 kHz clock and some other misc. digital stuff, so I added a couple of 0.1 mFd disc ceramics directly across it on the bottom side of the board. That reduced these signals to about 0.4 Vp-p, but the TV still won't turn on. The orange pilot light on the front is lit, but neither the buttons nor the remote will turn it on. The only way I can get the TV to turn on is to do the following: 1. disconnect the two power cables going to the two lamp inverter boards; 2. plug the AC power cable in. The 2nd green LED on the upper portion of the controller board now lights up when AC power is applied. 3. plug in both power cables to the two inverter boards while the power is on. The TV now works fine - all of the lamps light up, good picture, blue LED on the front panel, the remote works, etc. However, if I turn the TV off, and try to turn it back on, the small green LED on the upper controller board goes off, and the set won't come on! I've tried holding the on/off button down for over 10 seconds I read that this might re-boot the controller to no avail. The only way to get it back on is to go thru the 3 above steps again. I've read that there appear to be several versions of the firmware, and I wonder if this might be a firmware problem. If so, how/where can I get the proper firmware to install? Any suggestions? HELP! Please If someone would like to call me, please do at ************. Thanks, Gary W3DTN
