Re: LG 32LX1D will not turn on
OK, finally!, VIPER22A.
Check to see if it has DC voltage (set meter to 200V range) between Source and Drain pin, be careful not to let the probes slipped.Last edited by budm; 01-06-2014, 11:26 PM.Never stop learning

Re: LG 32LX1D will not turn on
The IC requires 14.5Vdc to start. You can try replacing that start up cap (sooner or later that cap will have to be replaced any way, just like in post 20), it may have leakage and not allow the startup voltage to rise up to 14.5V, or bad IC.Last edited by budm; 01-06-2014, 11:33 PM.Never stop learning

Re: LG 32LX1D will not turn on

Re: LG 32LX1D will not turn on
Hi guys, I didn't get a new TV like Captgrail suggested in post #77, I put this aside due to my mother becoming very ill and going to hospital. Spent the last 3 weeks at the hospital and then her house where they placed her in hospice. Unfortunately she just passed away on Monday and dealing with her funeral arrangements this week. Hopefully I can get started back up on this TV soon to get it repaired. I'll post soon what I get on my new DMM.Comment

Re: LG 32LX1D will not turn on
Both my ST5.0v readings are 00.7 when set on 200v DC on my meter. Everything else just reads 0.Comment

Re: LG 32LX1D will not turn on
If I have it on 20 it fluctuates between 0.78-0.83. Ok I just heated up C126 with hair dryer and plugged TV back in and it powers up for about 1 minute and shuts back off. TV screen comes on. I hooked up a dvd player and I get sound but no picture.Comment

Re: LG 32LX1D will not turn on
So it seems I probably need to replace that C126. Would I need to replace anything else? What would cause it to have no picture. I did what Budm suggested in post #91. Now what.Last edited by Crrose; 01-11-2014, 02:07 PM.Comment

Re: LG 32LX1D will not turn on
Ok so now I unplugged my dvd component cables and replaced them with just a red/white/yellow video cables and now I have picture and sound, plugged in a computer and have picture (unknown if sound yet since I need keyboard and mouse). Originally my problem was sound and no picture from HDMI cable. TV sat unused for a few months and when I went back to try to figure out what the problem was I had no power either.Comment

Re: LG 32LX1D will not turn on
I think change that cap and if you want to justify paying the postage buy some more
to replace caps of the same make on that board. That one has to work hard so has failed sooner. It will give a better base to work from if other faults become apparentPlease upload pictures using attachment function when ask for help on the repair

I'll try that, it could hurt unless my soldering sucks.Comment

Re: LG 32LX1D will not turn on
Well, I haven't done a thing since my last post and TV still running. Have an old Mac G4 hooked up to it using it in the garage for time being. It's what I am using right now for the monitor. Afraid to turn it off for fear it won't come back on. Think I should still try my hand at soldering and replace that C126 cap.Comment

Re: LG 32LX1D will not turn on
After 5 hours it finally shut back off and lost power again. Will be replacing that cap when I get it.Comment

Re: LG 32LX1D will not turn on
Ok C126 cap were Sam Young 105degree KMG 47uf 50v, the one I just bought is Jackson 47uf 50v 13A LHK...No one at Frys Electronics could tell me if they were in fact compatible. Not sure if the 13A makes a difference.Comment

Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited... -
Hi all,
I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.
Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line.... -

Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -
Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.
Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.
There's some logic behind it. As soon as I select an input I get only left...04-23-2025, 10:09 PM -
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the...
