Re: Vizio PE65-e1 Diagnosing help!!
I want to add the first time in the oven the TV worked for maybe a few mins but after i baked it a second more careful time and then new paste also i added an exhaust fan on the back USB type helps probably.
So glad to hear the news it works!
Oh and i immediately updated the firmware when the TV finally turned on long enough......Last edited by ajsterr4; 12-28-2020, 05:03 PM.Leave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
As of today the TV has been working for a few months after I baked the main board twice and re applied new thermal paste to the CPU after. I also mounted a usb fan on the rear of the tv to help exhaust heat inside - from what I gathered these octacore processors can overheat and cause the solder traces on the board to crack....Leave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
if anyone knows if a main board from the same model P65-E1 will work with another P65-E1 main board but with slightly different revisions.
Mine is 756XHCB0QK0300[B]10[/B]X Vizio Main Board, [U]715G7533-M01-002-005T[/U]
and i can find many similar like 756XHCB0QK0300[B]20[/B]X
Vizio P75-E1 Main Board (X)XHCB0QK011020X [U]715G7533-M01-000-005T[/U] +002
Vizio P65-E1 Main Board 756TXHCB0QK017
Vizio P65-E1 Main Board [U](715G7533-M01-000-005T) 756TXHCB0QK0100[/U]

Re: Vizio P-Series 4K tv with temporary sound and no picture P652ui-B2
Hey just wondering if the eeprom chip replacement on the main board solved issues as a permanent solution? I have a P65-E1 and put the main board in the oven for about 8 mins and the TV works now but only for a few minutes at a time. I even put a few fans with the back cover off to see if cooler temp would help but no avail.
How can one repair this main board if you can't find a replacement part?Leave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
I baked the board for about 8 mins at 380 and the TV works now... as others have reported. Can I install fans to keep things cooler and expect the board to last or can someone do a BGA board repair? I cant even find the exact board only different revisions within the P65-E1 model.
Update: Lasted maybe 10 mins while i was doing firmware the TV began to die displaying lines and blooming .... can i repair this board?Last edited by ajsterr4; 09-12-2020, 08:17 PM.Leave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
Well you were correct the +VM & +VA all read 18.95 volts with the TV plugged in and all the ribbon cables and connectors connected & PS_ON = 4.95 Volts
I threw the board in the oven i'll let you know if i get a picture
before the standby light wouldn't even come on just briefly when you plug it into the wall so i couldn't power the TV on and test i did have it plugged in though... good?Last edited by ajsterr4; 09-12-2020, 07:01 PM.Leave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
Thanks so much neil, just curious I thought 5v was the standard and you're saying 19v other people said if they seen more than 10v it's a bad power board. I'm a bit confused exactly what should the reading beLeave a comment:

Re: Vizio PE65-e1 Diagnosing help!!
Nvm got the heat sink off, the backside of the main board is a little sticky?? is that normal it feels like flux maybe covers alot of the back of the board. no burns tho.... Also my model and part number for the board 756TXHCB0QK0300 Vizio Main Board, 715G7533-M01-002-005T, (X)XHCB0QK030010X, P65-E1
but i found 715G7533-M01-000-005T will this work?? maybe a different revision?Leave a comment:

Vizio PE65-e1 Diagnosing help!!
Guys I have a 65" with no power/no standby light - nothing. Im in the midst of testing the boards right now to see which is faulty and looking for the STBY/SB/STNDBY (not sure) on the power board i don't see it anywhere like i expected. I would like to check the standby voltage could someone take a look at these pics and tell me what you think?
ALSO, how do i get the black plastic heat shield thing off of the main board - it has push in tabs but it won't come off?
The green circled connector in the photo is the one that runs back to the main board....Last edited by ajsterr4; 09-12-2020, 05:52 PM. -
Re: Vizio P-Series: P65-F1 "Standby Light Flickering 1 Second"
I should mention the standby light only flickers when i plug the device into the wall and then it goes off completely - other than that the tv is completely unresponsiveLeave a comment:

Vizio P-Series: P65-F1 "Standby Light Flickering 1 Second"
I picked up the TV and here's the symptons:
user said screen started going purple or green then went out, he hard reset TV and i guess it just stopped working completely.
When the TV is first plugged in the standby light briefly for a second flickers then stops... The rest of the TV is unresponsive... I havent taken it apart yet
What are the odds of changing out just the power board and other components are ok?
btw sorry for dupe posts i deleted the old one. -

Vizio P-Series: P65-F1
Hello BC it's a pleasure to be back asking for your help again
I've tried fixing TVs in the past with either mild success or at least recognized what was wrong and gave up if it became out of my reach to repair.
However yesterday my home tv got cracked so I'm looking at a P65-F1 for $150 - seller says it "receives power but will not turn on" and the power source needs repaired.
Right off the bat what would you suspect if anyone has experience with this TV? My logic is that I can buy main board and power board and possibly fix it for a good budget....Last edited by ajsterr4; 09-11-2020, 09:15 AM. -
Re: Wine Enthusiast wine cooler, no power. Model # 272 03 29
Alright will someone answer me once and for all how can I do this and not get killed? I have to test alot of components and would like to do so with the power unplugged, or rather if it needs to be powered then how can I do it safely?
So far I need to table top the board and check t5,t6,t7 transistors, resistors on the snubber network, (pretty sure rectifier is bad 0 reading) and I guess while I'm at it check the secondary side capacitors.
I'd like to do it on a table, why...Leave a comment:

Re: Wine Enthusiast wine cooler, no power. Model # 272 03 29
I'm pretty sure I'm not getting a reading at all at the rectifier. Also fuse on the power board is blown after the spark incident.Leave a comment:

Re: Wine Enthusiast wine cooler, no power. Model # 272 03 29
Which large capacitor? Both?
Btw I plug in unit and theres no lights and no button to power on but I imagine its "powered on" in circuit. I'll test it in DC this way....Leave a comment:

Still works.. reading a 3v cell @ 3.12 voltsLeave a comment:

Re: Wine Enthusiast wine cooler, no power. Model # 272 03 29
I checked before spark with correct meter setup with no readingLeave a comment:

Re: Wine Enthusiast wine cooler, no power. Model # 272 03 29
I checked the rectifier ac voltage and it sparked twice... should my multimeter be the other way? Spot looks burnt now
I tried multimeter with red in the other slot and it didnt spark, no reading or rather went from ~50 to 0 quickly.
Fuse looks good...Leave a comment:
