Vizio VF550M - Standby light only

[zdsh07p9]

So yesterday I bought a 55" Vizio that I plugged into the electrical outlet (Vizio Orange standby light comes on) - I press power and nothing. Press power again, same result - over and over. I have been reading a lot of places where people bought eeprom for this board and was wondering if you guys really think it could be that?

The main board number is 3655-0022-0150 or 0395. They don't have one on ebay /shopjimmy / tristate module

You need to do some voltage readings first.
Good clear pictures of the back of the TV so we can see how all the boards are connected will be a good start.

Re: Vizio VF550M - Standby light only

At the beginning I was thinking this is the main board problem but a friend and I were discussing this - It could possibly be the power board as well. The power board gives power to the main board (I am guessing for the orange light to be on) and then the main board sends a signal to the power board telling it to kick on ( I think that's where maybe a problem is) But what do I know.

On the Main board, above the HDMI's on the left, there is 2 black squares, one of them is not hot, the other will burn my finger off, if this means anything. Also, I get STANDBY Voltage of 5.11 coming from the power supply to the main board.

"there is 2 black squares, one of them is not hot, the other will burn my finger off," That is not normal. Do you know if this TV was hit by surge or lighting?

Re: Vizio VF550M - Standby light only

The one on the left is hot, reallllllly hot. (like the description?) I can not confirm whether or not it was hit by lightning. Let me know what you would do from here, or what I need to test boss!

There is not much you can do for the bad IC, you will need new main board.

Have been looking for weeks! (not really, a few days) Thanks Budm! Wish I could help you out with something.

The main board is not cheap, over $100 dollars. I have a feeling that the TV got hit by surge or lightings which will typically damage the HDMI section which is connected to cable box or SAT box.

has anyone been able to find the main board for this model? I am having the exact same problem and we just had a major lightning storm so I assume that my TV was hit. I am no able to find the main board for sale ANYWHERE! If anyone can help me find one I would appreciate it. I already changed out the power board with no success, still stuck with the orange standby light. Please Help!
