    TFT LCD, and Plasma tv's are much easier to troubleshoot than conventional CRT tv's. And the circuits are far more intuitive which helps a trained technician troubleshoot a fault faster. All flat panels use "service software" for test-mode. Some need a PC for test mode commands together with OEM software. Other's require shorting out and couple of points on the circuit and/or hidden key commands from the remote control.

    Provide the year and model number for the Vizio tv and I can try an locate a vender for your part. I'll also search my shop to see if we have one.

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. Sincerely, Dave

Turn o n the tv and it has a loud static hum that is ever present. it dims out a little but never goes away.


This can be cause by the inverters arcing or faulty insulation within the high voltage section of the power inverters; associated with the screen.

Sony tv mfm ht75w tv doesn't stay on, works for 10min sometimes,, other times only sec. i opened it all the caps seem ok, any ideas


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.

My television screen went black, but there is has sound


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.

PINK SCREEN ON DAEWOO PLASMA TV


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

Flat panel tv


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
