I got this tv from the trash opened it up, and found this sub board taken off the power board. I want to clean it up but I don't know what one part is. Any help would be appreciated.

Re: Panasonic etx2mm704mgh
It will be MC201 or MC301 module, common fault on this PSU. Boy, that is pretty bad!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic etx2mm704mgh
What I really need to know what is the tiny component I pointed at is. Its black and has ?20 First number could be a 1 .When I get done this thing is going to look like jumper city. LOL Thanks againAttached FilesComment

Re: Panasonic etx2mm704mgh
Looking at the video( 8 minute marker) it looks like a diode, has a white band on it so you should be able to test it but I just did one of these a little better than yours and did just the 1uf ceramic cap and all good. witha bit of care and some neat links I reckon you'll salvage it but a full strip of that ic and clean all the solder debris and excess.
I had 2 blink so just did the 15V module.Comment

Re: Panasonic etx2mm704mgh
2 blinks can also be bad power FETs & fuse for VSUS tract, if that is the case replace TEA1611T at the same time.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Once I get this to power up I will post some voltages,and take more pictures . The videos were very helpful. ThanksComment

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.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

My old plasma died when one night recently. When I got to it it was giving a 3.3v sos (3 blinks).
I chased my way through the PSU, and a board, with no results.
Replacing a few bulged caps in the PSU, I eventually got to the SC board that had piles of shorts, a quick cheap replacement from china and the tv powers up again, except
I only have the right half of the picture.
Left half is completely blank.
now the c3 board running this side of the screen has its 3.3 and 5v onto the buffer ic and its got the 60v, so that all seems good.
all the other voltage rails...09-24-2024, 04:39 AM
