Ex TV Maintenance Eng., now retired and not up to date with flat panel, LCDs. Would like o have an idea what I'm getting nto and how to go about lamp replacement in my Vizio that I'm quite satisfied with.
Thanks for your response. I don't actually have any problem. It's just that occasionally some program will seem to have less brightness and I'll start wondering if the lamp is getting ready to go. At least I think there's a lamp that could go. Have to admit my understanding of LCDs, Plasma, DLPs, etc. leaves a lot for me to study. Was hoping there might be an available service guide that might prepare me for that eventuality.
Nice to know you're here to help when the time comes. I'll be doing some reading in the mean time.
At one time I was confident I could fix anything in our studio or transmitter. Too many years ago.

Screen-shots to defctive LCDs are given. You can see and compare it to that of your TVs' and can get an idea about the fault.
3320-0032-0150. Question - is this board in other 32" LCDs? I see the entire LCD all over EBay w/cracked displays for CHEAP (since the LCDs are so pricey the unit is parts only). Thanks again! cheak out them on ebay try new board
Check the back-light is present. If not, check and replace back light inverter board. http://electronicshelponline.blogspot.com/. If you wish to get more details, check this link. It has details about Panasonic TC-26LX series LCDs. Pull up older posts.
Please clarify whether the entire tv powers off or only the screen turns off and you can hear the sound so that we can continue with the diagnosis. Sony LCDs are notorious for backlight inverter failures.
Make sure your tv is on the right input first of all. The newer flat panel lcds combine the componenent video (red , blue, green) with the composite video and audio (yellow, red, white). If your tv is on the component input then you hear audio from the composite input since the audio inputs (red, white) are shared. Look for a source or tv input button on your remote or the tv itself and try pressing this button unti you see a picture with sound.
Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair
disconnect the x and y sustain boards from the power supply. then check the flex connector to the screen and reseat them. check connections on c boards at bottom and screen connectors. reconnect the power supply only after all flex cables are reconnected or charge from supply will burn flex cables. if still preent replace correcsponding c board. if still no fix replace panel.
Hi am roshan...the one who was chatting with you (TV)...there was drop in the server thats why we lost contact...the best chioce is buying a LCD.This is the reason
Apart from being price competitive, LCD has the edge over plasma in several other key areas. LCDs tend to have higher native resolution than plasmas of similar size, which means more pixels on a screen.
LCDs also tend to consume less power than plasma screens, with some estimates ranging that power saving at up to 30 per cent less than plasma. LCDs are also generally lighter than similar sized plasmas, making it easier to move around or wall mount.
i lost by payment due to that problem...at least if you can PLS rate as FIXYA...for my help..catch you later
