Re: Vizio P50 HDTV20A
The menu looks great and just as a follow up there are two of those resistor style fuses in addition to the standard glass fuse on the xmain. The one that failed was the small resistor fuse located directly next to the glass fuse. I am watching Netflix on the t.v picture looks great and already have a buyer lined up.Comment

Please tell me you are going to replace the fuse with an actual fuse, not a piece of wire.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Vizio P50 HDTV20A
Hello, new to TV repairs and electronics in general. My Vizio 50 inch plasma TV from 2007 went completely dead save for the amber standby light. I was able to source a used power supply from a TV repair shop (a Sony power supply that was told is better than the LG that came with the TV). It still did not work until I bought and installed a main board. I now have 99 percent of the TV back. I have a vertical one inch line that runs on the left side of the TV. I was trying to decide if I damaged the PDP during the repair or if it is something else. The line appears to boot up white and then sparkles in areas changing into multiple colors. It does not affect the TV since it is localized within the vertical line. Thanks for allowing me to post to this thread, as I was unable to create a new thread.Attached FilesComment

Hello, i am working on Vizio M70-C3. It can hardly power on, it takes 15 power button presses or remote. Seems like eeprom problem that I seen before but all reading online says that this tv has power board or main board problem.

When it goes into tv mode it only shows good picture on left side of screen, right is all scrabbled up. pic 2
When i start youtube picture shows on left side fine, right is all scrambled. pic 2
When i click video to start playing picture goes black(like when you change... -
Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright... -
HI all,
hope someone point to the possible issue before I start buying replacement parts.
Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
Backlight stays on all the time,
Sound works fine.
screen keeps changing form black to full picture in about 1sec intervals.
Picture looks fine with no visible artifacts.
I have disconnected backlights and flashlight test confirmed that picture is still doing the same.
Disconnecting left and right ribbons on... -
I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off.... -
Hi,
I have a VIZIO E70-E3.
Symptoms: Black screen, no picture, but LED backlights are working.
I probed the power board and voltages are as listed on the board.
Main board appears fine, too.
I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
There are two separate ribbon cables feeding the LCD.
If both are connected, the screen is black.
If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...
