Thatâs a heartwarming story KB nut

The same thing happened to me a few days ago. I confirmed the power supply was working, but still no lights. To make a long story short I determined that the circuit board power was shorted out. I opened it up and found that a capacitor (1C37) had shorted out, and so I removed it. This fixed the problem.
This power cap is one of many like it, and any one of them can short out due to defect or poor quality. But in most cases the offending cap can be removed and not replaced.
I have test equipment, but you can usually find a shorted power cap with your finger as it will get hot. If you are not skilled with electronics repair I recommend you return the unit as you will need skill with a soldering iron to make this repair.

Regarding Tablo suddenly dying.

I looked in mine to see if I could see a burned out part (sometimes there is visible scorching) but no luck. My electronics skills donât match yours.
Where on the board was your burned out cap? Maybe I will look again. I donât think I put it in the trash just yet.
Failed capacitors do not necessarily show burn marks. I would also look for split sides or bulging top and swelling. Does opening and removing a failed capacitor void any chance of warranty? According to this forum Tablo has been giving a little leeway in warranty support.

Did you try replacing the power supply. They do go bad from time to time. Maybe using the new one on your old Tablo to see if it comes back to life.
So, there has been reports about the 4th generation power failures, unit lasting only about a year and the led light dying, wouldnât this make the Tablo folks take a closer look at their units and come out with a better product instead?
I have the HDMI version and have none of this issues, I have only owned the 4th generation for 2 months and would hate to have this problem some time in the future, I think the Tablo people should do better

In my case the failing cap was a SMT at 1C37 near the RF shield on the top side of the board. It showed no visible sign of damage.
I measured 0 ohms on the power plug so I knew something was shorted. So I used a bench power supply to pump power into the board to locate shorted component. When a short occurs in a component and you give it power long enough the shorted component will either get extremely hot or blow all together. in this case, I just used my finger to feel for an overheated component. After removing it, I confirmed it was indeed shorted - and the Tablo has worked since then.
This was a generic power bypass cap, one of dozens like it on the board, and simply defective or poor quality.

My unit is about 6 mos old. I suspect the root cause is the use of a low quality/cost manufacturer of these caps.

The first thing I did was test the power supply and it worked fine. This problem was caused by a shorted component and is resolved. There is no guessing involved. But this case doesnât mean that all power failures are bad components or that all supplies are good.
unless youâre a nerd like me, I recommend taking advantage of the return policy.
