Re: Vizio SV422XVT blinking amber/white power light
Thanks Nomoresonys, I checked them off board and I got no reading at all on the ESR or on the multimeter for 3 of them and dead short for 2 of them. Thanks for your input.
What?

Re: Vizio SV422XVT blinking amber/white power light
I tried to replace the teeny tiny capacitors with standard soldering equipment and buggered the board. The tv is too old to find parts for, just gonna hang it up and go home.Leave a comment:

Re: Vizio SV422XVT blinking amber/white power light
Thanks for the response retro. I checked all the caps with an ESR meter, I am pretty confident they are ok. I think the 2 caps that were bulged was because I overheated them trying to see if heating the board would make something happen.Leave a comment:

Re: Vizio SV422XVT blinking amber/white power light
I think I am pretty much screwed on this one, the main board is not available anywhere, I can't locate a schematic, I have no idea what the ratings on these tiny caps are and if someone did have the board they are priced way too high.Leave a comment:

Re: Vizio SV422XVT blinking amber/white power light
I was poking around with an ESR meter and discovered 3 tiny smd caps close to connector J1 that indicate they are open. Would 3 tiny smd caps keep the tv from working?Leave a comment:

Vizio SV422XVT blinking amber/white power light
Good day, hope all are healthy and cozy. I could use some help with my malfunctioning Vizio with a blinking power light. I have narrowed the problem to the main board but not sure what to do next. I guess it would be good to start with what I have done.
Problem:
I have no image, no sound, blinking power light. (left it plugged in overnight and it was still blinking the following morning). I tried the Vizio recommendations (hold power button for 30 seconds, press reset button, check the outlet is live)
Power Board:
I am getting 5v only. I have unplugged... -

Thanks budm and CapLeaker for responding.
Something bad meaning proprietary chips?
Can it be fixed or should I just toss it and look for another Main Board?

Samsung UN50EH5000F No Image, No Backlight, No Sound, No Standby Light
A friend brought this TV to me 'cause he knows I like to tinker. No stand and no remote control. I have taken some measurements so what would you like to see first.
I plug the TV in, no apparent activity. Push the on/off button nothing happens.
Took the back cover off, plugged in the TV and it looks like the PSU is working because there are voltages at the connector going to the Main board. When I unplug the Main board from the PSU the backlights come on but nothing else happens. Still no sound no standby light, no image.
I have already replaced the eeprom chip with the ShopJimmy...Last edited by What?; 11-02-2019, 01:34 PM. -

ivtec,
I found mine on Craigslist for $20 and found the diode problem thanks to this forum. It ran great for 2 1/2 years or so and then this main board problem. Best TV I ever had, great picture, 4 hdmi connectors and the usb connector, which reminds me I successfully updated the TV software by using the donor TV model number for the Philips software search. Thanks again!Leave a comment:

Re: Philips 46PFL5505D/F7 blinking power light no pic no sound
OK, guys, I got the A01Q6MMA-002-DM Main Board in the mail yesterday and installed it today. I hooked it up, plugged it in and to my surprise, it worked!! My TV is back up and running on the wrong board I purchased from eBay for $94.
A quick update.....
My Philips TV is model 46PFL5505D/F7, my main board is A01Q5MMA-001-DM (A01Q5UZ on the board sticker).
The replacement main board came from Philips TV model 46PFL5705D/F7, the main board is A01Q6MMA-002-DM.
The only thing I have noticed is the...Last edited by What?; 11-14-2018, 12:11 PM.Leave a comment:

ivtec,
yes I bought it, thank you very much. The specs are identical to my existing board except a couple things like it has Netflix connection. I bought another board the day before yesterday, it is not going to work, I guess I will have to resell it.Leave a comment:

Holy Moly ivtec, I think you just pulled my bacon out of the fire!! I saw that this morning and passed it up....I thought it was for an LED version. I will check on it, thanks a bunch.Leave a comment:

How close does the PCB assembly number have to match?
My tv is a 46PFL5505D/F7, MFG Date is May 2010, silk screened board #BA01P5G0401 2_1, board sticker #A01Q5UZ (A01Q5MMA-001-DM).
Donor tv is a 46PFL7505D/F7, MFG Date is Feb. 2011, silk screened board #BA01P5G0401 2_1, board sticker #A01Q7UF (A01Q7MMA-001-DM)Last edited by What?; 11-08-2018, 06:52 AM.Leave a comment:

CapLeaker,
I don't detect anything getting really hot, there are a few components that get hot but not so hot I can't touch it.Leave a comment:

Re: Philips 46PFL5505D/F7 blinking power light no pic no sound
I have found main boards for different size tv's (40 or 55") that look exactly like mine. Same product series, slightly different part number on the boards but exactly same board number silk screened on the board. Would they work on my 46" tv? The only difference I can see is one capacitor on my board is not on the other boards even though there is a place for it, same part id number (C3024)....Last edited by What?; 11-07-2018, 10:18 PM.Leave a comment:
