Ok, i will do that. Is there a possibility that only the power board that is bad?

Re: 40" Philips 40pfl4706/f7 No Power
More than likely you'd be looking at replacing both boards, but there's a small (unlikely) chance that the P-ON signal is meant to be LOW (0V) and the main board is doing a self-test which fails... since you have no power LED this is unlikely.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: 40" Philips 40pfl4706/f7 No Power
That's the problem replacing multiple boards ain't worth it given the prices of these units in working condition (used and even new). I have several Philips HDTVs -- 42PFL7422, 19PFL3504, and couple others all with power related issues. It seems Philips TVs usually have that as their weakness.Everything, including my Philips TVs, are subject to birth, disease, old age, and finally death.Comment

Re: 40" Philips 40pfl4706/f7 No Power
Good news. I got the power board, and after installation the TV works great. Well, the service center diagnostic was wrong. Thank you Tom very much, you saved me lot of time, money and hassle. They wanted to charge me $390 for replacing the wrong part. I got it fixed for only $35. I really appreciate your help Tom. Blessings.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello partners.
Could someone tell me how to make this Philips TV source work without the mainboard being connected? The model of the board is EAX65423701 (2.1) and the model of the Philips TV is 40PFH40009/88.
The TV is dead, there is no standby light, however there is a voltage of 12v on the pins ( included 12v VAU ) and 3.2v on the PS-ON pin (see photo) when the power board is connected to the main board. If I disconnect both boards I only get 8 volts on 12v pins. I would like to rule out a fault in the main board by making it work, but so far no one has been able to tell... -
Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
