Re: Vizio bp50-hdtv2a
According to this post, if it's the same Y-Sus, those resistors appear to be 10 ohms: http://www.fixya.com/support/t124065...tv20a_am_going -
Re: Vizio bp50-hdtv2a
I'm working on 2 of those same models, if you haven't got the answer, I can make measurements for you.Comment

Re: Vizio bp50-hdtv2a
Thanks capkid plasma Ron do you no what mosfets to replace
There's a kid on eBay that says you need to replace 6
Of them but my board has 10 also I'm getting 5.2 ohms
Each on my resisters should the be 10 ohms each or together
ThanksComment

Re: Vizio bp50-hdtv2a
The resistors are 10 ohms each. Did you lift at least one leg of each resistor from the circuit to check the resistance? If they are in parallel, and you didn't lift a leg, the 5-ohm readings you got are correct.Last edited by capkid; 11-28-2013, 02:27 PM.Comment

Re: Vizio bp50-hdtv2a
Ovalking, Sorry I really can't help much with component repair. I pretty much just do board replacements. The set(s) that I'm working on are the VP50HDTV10A and I see that the Y boards are EAX34151601. I don't see any resistors labeled like that on my boards.Comment

Re: Vizio bp50-hdtv2a
Is the screen totally black? Do your buffer ICs have any burns?Last edited by capkid; 11-28-2013, 03:27 PM.Comment

Re: Vizio bp50-hdtv2a
Yes one on top board has pin hole in it I think I found
One bad cap and 6 hidden mosfets does any on no
Part number for mosfetsComment

Re: Vizio bp50-hdtv2a
What do you mean by "hidden" mosfets? A pic or two might be helpful. This TV sounds very similar to the infamous HP-T50 series TVs, where the K2837 and B20NK50Z (this one sometimes fails) mosfets fail: https://www.badcaps.net/forum/showth...t=24844&page=7
The repair kit you referenced earlier is probably this one: http://www.ebay.com/itm/SAMSUNG-Phil...-/130975615950. The buffer will obviously have to be replaced or repaired.Last edited by capkid; 11-29-2013, 11:46 AM.Comment

Re: Vizio bp50-hdtv2a
They were below heat sink behind blue resisters I think
I'm new but I'm learning thank everyone here for the help
Thanks capkid ill look at other thread when I get off workComment

Re: Vizio bp50-hdtv2a
You are correct capkid that's the kit there is 4 that are the same
And 2 that are the same do you no part numbers ?Comment

Re: Vizio bp50-hdtv2a
On my board, which is LJ92-01490A for the three 50" Samsungs I worked on awhile back, I had to replace these mosfets on the lower bank:
- 88N30W (four of these)
- K2837 (one of these)
- B20NK50Z (one surface mount mosfet)
I'm not sure what's included in the eBay seller's kit. Also, I've purchased from this eBay seller (SLP5188) numerous times without an issue: http://www.ebay.com/itm/AP88N30E-88N...item2ecbb5a1e9Last edited by capkid; 11-29-2013, 04:48 PM.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
vizio e650i-a2 (LWJAOZBP Serial) led backlight flashes then turns off, has video (via flashlight) and audio.
panel: au optronics T650HVN05.4
72 led total on 12 strips, 6 led per strip wired in three groups of 24 (led driver board has three anode and three cathode pins)

Hi.
picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED... -
Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.
It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....
