I have a vizio Vp50hdtv20a with no picture. I replaced 4 2200uf caps on the power board, 1 680uf cap each on the x and y boards. There is clicking and 1 led lit onthe y board. Any more tests i can do


If the board is repaired and installed check the output is in accordance with the manufacturer's specifications

clciking is probably the sound of electrical discharge, i.e. something is not conducting but is shorting out
This is a generalisation but there should be no such untoward sounds present

I have a vizio model vp50hdtv20a the picture is slow to come on like it needs to warm up and i have no sound any suggestions to what the problem might be?


Could be the Tcons flex cable connections. If that doesnt solve it then the Tcon would be suspect. If you need a Tcon you can get one from www.tvrepairworld.com

Black screen with sound


My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.

Good day sir Thor!!!!


I already encounter that kind of problem many times..It looks like all normal even the green power light is not blinks or change to red or amber color but still no sounds or picture on TV..

Sometimes it will happen to plasma TV in all brands and model..It cause of faulty main board..

This is the sample picture of main board of your unit..Part # (3850-0142-0150)

http://modulesrus.ecrater.com/p/11497716/vizio-main-a-v-3850-0142-0150

Just replace the board to fix your TV and it works again..

Note: When you install the board make it sure that the static energy on your body discharge to ground to avoid corrupt of main board IC..

EXAMPLE: open the cover then find the main board..before you do that make it sure you hold the metal portion of your TV to discharge static after that you can now freely replace the board and also make it sure to memorized the connector to avoid damage to make it sure take a picture on it before unplug connector for future reference in case..

again discharge static please!!!..Only few tech or other people know this that's why when they install new boards its not works even it is new..I discover this base on my experience and study..

Hope it helps..

Please don't forget to rate!!!!

Thank you using fixya..

I have a vizio model # VP50HDTV20A I have sound but no picture and checked all the fuses on the power supply board and the Y SAUSTAIN BOARD all ckecked good caps look okay.


more then likely you have a bad sustainer board. Do you light coming from the panel. Sometimes theres an IC chip under the heatsinks and that goes bad causing the screen to go blank. Let me know if that helps at all.

How to reset tv. Have sound but black screen


LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.
