Again! Turn On Turn Off and it's the T-CON Board AGAIN

by BooSamSung / October 15, 2011 6:20 AM PDT

Bought my Samsung LN52A750R1FXZA late 2008. TV started the on/off problem in Aug 2010 but it would stay on. Eventually it went into the endless on/off loop and I had to unplug it.

The first one lasted years. The new board a few months. It sounds like your tech didn't find what was causing the tcon board to fail. I'm not a Samsung service tech so I have only my electronics design experience to draw on that your first tech didn't find the cause.

Thanks for the reply. The t-con board was replaced in Aug 2010. It just went out again last week, so it lasted for over a year. I'm wondering if the capacitors could have caused it to go out earlier than it would have normally. I posted a picture of the capacitors. Only 2 of them look like they have a slight bulge.

But there is only one criteria for those caps. "Perfection."

If you haven't done the BAD CAPS research it's found with google, what companies made them and we see them all over. If a tech does not change imperfect caps, I'd get them to or change techs.

Qualified Samsung field engineers are only required to replace capacitors on affected model tvs that have been authorized by Samsung for replacement and if the capacitors visually appear faulty or if they fail a capacitance meter test.
If the capacitance value tolerance is within 5uF +/- for any electrolytic capacitor at room temperature, then it is acceptable and does not need to be replaced as temperature levels will affect and induce different capacitance levels when tested.

As an electronics designer I know what you are writing.

But you can do much better by doing the BAD CAPS research. When you send technicians into the field you give them orders and the better ones are in a word "better."

The techs that only follow orders are cruising.

authorized technicians for Samsung have to follow the company service procedure rules set forth in the contract by Samsung or face contract termination.
while many authorized service technicians go above and beyond standard service for the customer, we cannot start replacing parts/components "just because" and especially without upper level approval.
every part/component ordered and/or replaced is tracked and accounted for by Samsung.
if a part/component is replaced that has nothing to do with the issue(s) at hand, the authorized service center may be responsible to pay the cost of the part(s) replaced.

Let's hope you get a better tech than that!

There are great techs and there are ones that only follow orders.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
