Re: Westinghouse Service Menu ?

Winner winner chicken dinner!

Menu-0-0-0-0. Thanks neilc6.

I haven't went through all the settings yet but what's better (or what's the difference?) between eeprom_init and factory_reset ?

Westinghouse Service Menu ?

Model WD55UDR101. I believe this was sold at Canadian Tire here in Canada.

Want to limit the current to the leds - the standard Picture menu is useless for that. Trying to find it in the service...

Re: Westinghouse WD55UDR101 No Audio from Speakers

I have decided to keep this tv and as such the functioning of the built in speakers is not critical.

Thanks for your input.

Re: Westinghouse WD55UDR101 No Audio from Speakers

I did plug and remove several times and did not hear anything at all from the speakers not even the faintest noise or level change.

Did not try cleaner but I will inspect the jack itself a little...

Westinghouse WD55UDR101 No Audio from Speakers

I think this set comes in many flavours from the usual suspects, RCA, Proscan, other house brands etc. Main/Power board is CV6586H-A50 P/N 34020824.

The set has no audio from the speakers but if I...

Re: Nvidia Shield TV 2017 Dead

I removed U504, U505 and U506 which cleared the shorts around the last two but still a low ohm short in the area of U504 and now the MAX77620a is heating quickly and the board is drawing 270ma when...

Re: Nvidia Shield TV 2017 Dead

I found and removed a shorted mlcc under one of the shields. I still have a bank of shorted caps so still have a short somewhere else. Problem is I can't trace the vcc line because I can't see the...

Re: Nvidia Shield TV 2017 Dead

So I thought more about this and for anyone having the same brain block as I was I've determined you can use ground anywhere on the board since the shortest path will always be through the shorted...

Re: Nvidia Shield TV 2017 Dead

No, the esr meter also reads ohms when it doesn't detect capacitance. Since I'm checking a circuit with a short the caps don't charge up and it measures the resistance of the path to ground.

My esr meter reads low ohms. I'm going to read up on the method.

Re: Nvidia Shield TV 2017 Dead

When using ohm meter method do you use a common ground or do you measure across a device, like both ends of a cap ?

Re: Nvidia Shield TV 2017 Dead

Some caps are shorted to ground, yes, there is a short somewhere.

No it didn't boot with the 1054P removed. That ic is some current sensing chip or was acting like one, resetting every half second...

Re: Nvidia Shield TV 2017 Dead

There are more shorted caps along the back of the board near the ports, too many to start removing them. There are no shorted caps in the other areas including the cpu/gpu.

Would it be ok to...

Re: Nvidia Shield TV 2017 Dead

You can't see on the pics but those four pads that are shorted are all tied together. I didn't notice it myself until now. Q15 is a dual channel mosfet which I removed and does not test shorted.

Re: Nvidia Shield TV 2017 Dead

With Q16 removed I have 19v on pad 4 and zero on the rest. A continuity test shows pads 1, 2, 5, and 6 shorted to ground.

Nvidia Shield TV 2017 Dead

This is the one with the 19v supply with the proprietary connector. Looks like a USB-C but it is not. There are many complaints of this adapter failing. I cracked mine open and found a vapourized...

Re: Free TV- Repair Help Appreciated

Don't use heat - these will peel off like tape. There's a small chance afterward that some residue is shorting some of the address lines you can then go over the pads with a magnifying glass to spot...

Re: UN65HU9000 T-con

Does the tcon work without the cap ? You may have other problems beside it.
