Hello, my name is carlos, I am new in this forum. I am sorry if I am not doing the right way to post over here. Please let me know if is wrong in that way I try no to do it again or let me know the correct way to do it. I have a dell plasma tv with no sound and no picture. I replace all the boards, but main logic board and the tv still no sound and not picture. When I replace the power supply board the tv work for about 2 weeks, but after I had lines on the bottom of the tv, so I ordered the y-sustain board, nothing the lower and upper boards, etc. still nothing. If you need more info, please let me know. Thanks in advance

Re: Dell 42" Plasma tv
The main board is what tells the power supply to turn on and controls the audio.Comment

Re: Dell 42" Plasma tv
Sounds like you need to start with the basics.
Disconnect Z and Y boards check for VS voltage coming from power supply first. Also check for stand by 5v to the main board from the power supplyDid I leave the soldering iron on?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,
I'm Working on replacing an Inductor on this Dell's board and I need to come up with a compatible replacement. As much as I would like to smash a comparable 2R2 in the same spot I'd like to confirm the specs before confirming a killed board. For my purposes I'd be happy with a second opinion on the replacement inductor or the actual schematics/board view. As this is a commonly used Dell Rugged in my local service area, schematics would greatly help in the future.
Thank you in advance for any assistance you can render.

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).
I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).
Looking on google I found this:...
