I have a Spectroniq PLTV-3250 that is missing the 5 volt side of the power supply. I was following a post by plain bill but never seen him again after the first few post any help please

Re: Spectroniq PLTV-3250
In the spirit of the season I will NOT tell you my opinion of those who cannot take instructions. A simple search on PLTV-3250 brings up 5 hits. One is this thread. Another is a thread in which retiredcaps suggested using the search feature.
IF you had done so, you would have found a long thread which gives a lot of information on repairing the power supply. You would also have found a shorter thread which also has some information, as well as another thread which mentions similar problems on a set that uses the same supply. Somewhere in those three threads it mentions that the power supply is available on eBay. Instead of following retiredcaps advice, out of some misguided perversity you started another thread!!
NOW, if you are actually interested in getting your TV working, I will point out that buying a complete power supply may be the easiest way. If you wish to repair yours, I will help. First, read the links in my signature on the suggested way to take and attach pictures. Attach good, clear pictures of the top and bottom of the power supply to the long thread I linked above. I will reply when I have free time. Because of my plans for today I may not be back here today.
PlainBillFor a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

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.

I 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... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.
i know that in linear power supply the noise will be very low comparing to SMPS supply.... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
