Re: Insignia ns-42pdp no power
also there is a red LED light on power board. when I turn Tv on and hear the buzz from the cap the blue light changes to red on front of Tv and the LED on power board lights up. I assume this means there is a problem on power board. LED is marked LED601 -

Unplug the two large connectors on the top left of the board then power it up again. See if it stays on.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Insignia ns-42pdp no power
with both unplugged the Tv stays on! I tested pin 5vctr at 5.2v if I plug in x601 connector then Tv goes to standby and red led lights up. but if i just plug in connector X602 the Tv stays on and I get a picture on half the screen. X601 run over to the right side of tv.. I guess it controls the backlight and the other half of screen?Comment

Re: Insignia ns-42pdp no power
You have a bad Z-sustain, I suspect.

A plasma panel doesn't have a backlight. It works entirely differently from an LCD. Each pixel independently emits its own light compared to an LCD which uses a uniform light source and blocks/allows through out the light at the pixel level.Please do not PM me with questions!

Re: Insignia ns-42pdp no power
Yeah. That's the Z-sustain. Picture now looks purple, or dim, and/or slow to update, with that board removed?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Insignia ns-42pdp no power
Remove the leftmost fuse from this image.
You should still have a dim/blur/ghosty picture but all of it should work now.

Re: Insignia ns-42pdp no power
Yes, or do the repair in the video if you have the equipment. If you can remove it, soldering a new one on is easy. But not everyone can as it takes a lot of heat.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Insignia ns-42pdp no power
Note you only need to replace the Z-sustain, the Y-sustain is fine for now.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Insignia ns-42pdp no power
I picked up a used sustain board from a television repair shop in town! and I'm happy to say that what's the problem. however I did notice that when the screen is black there are red speckles.. they only show up when there's a black screen other than that works fine. from what I read the voltage needs turn down?Comment

Re: Insignia ns-42pdp no power
It looks like LG plasma tech... Red sparklies can mean control board needs new firmware but sometimes you can get lucky.
Post a picture of the Y-sustain and power supply so I can highlight the adjustments.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Insignia ns-42pdp no power
OK, first you want to drop Vs slightly.
With the TV running, slowly adjust Vs and measure it with a multimeter. Drop it by about 5V.
If the sparklies do not go away, try "setdn" adjustment -- tweak one way, if it gets worse, go the other way.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI 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.

by PantherDaveHi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

by GLISITHi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
by cajoegHello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.
The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV... -
by sam_sam_samI have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... - Loading...
