MSI GTX 970 4G V316 1.1 Loads of lines across screen suspect memory??
Recently purchased this MSI GTX 970 Gaming 4G graphics card and card shows plenty of lines when booting up to bios and into Windows.
What are your thoughts memory issue as I don't have that much experience repairing graphics cards?
I have checked before plugging in card for shorts on the 12V power rails, PEX etc otherwise I wouldn't have plugged the card into the motherboard.
The screen shuts down if I load the drivers on the card.
See attached pictures. [ATTACH=JSON]{"data-align":"none","data-size":"small","data-attachmentid":3647383}[/ATTACH]...

The issue with these sets is the TV gets stuck in standby until you power cycle the TV. This is down to firmware which there is a German site which has the download links for all these Toshiba sets.
If you searched on this site you would have found it!

I don't have the model now it was sold on ebay a while back! I cannot see what you say would work as I did remove the black plastic cover and did try to pull apart the unit, it didn't budge under a lot of pressure. The only way I would see it working was if you were to push a metal or strong pin into the hole possibly releasing the red plastic somehow. Too late to try now.

A bit of common sense would be to download the service manual for the TV! A quick google will show a free download for it here [url]https://elektrotanya.com/samsung_un40es6100_un46es6100_un55es6100_un60es6100f_es6500f_un46es6600f_un55es6600f_un40es6820f_un46es6820f_55es6820f_chassis_u76a.pdf/download.html[/url]
Then start reading and checking for voltages on your power supply, ensuring that you are fully aware of the risks when working with mains voltages! If you are not then leave it to someone who does.https://A bit of common sense would ...A quick google

Good news I have managed to track down a high ESR Samxon 10uF 50V capacitor that was causing the issues
Picture attached for location of the high ESR capacitor around 2.2ohms, replaced with a Panasonc FR capacitor. I guess it was cooked with the heat inside this small unit especially as there was dust build up by the fan furthering the build up of heat inside the unit. I did also notice another 2.2uF 50V capacitor that did also have a slightly high ESR (circled in red), however I didn't have a suitable Panasonic capacitor to replace it with. The yellow circled capacitors were the ones...

Dell XPS One 2720 AIO Liteon PS-3261-9DA not starting up immediately
I suspect the issue is with the power supply Liteon PS-3261-9DA as apparently they are notorious for issues with them. Has anyone else had similar issues where the PC tries to boot up a few times before finally booting up. Now I have opened up the PSU which shows no signs of any capacitors failing. I did remove one capacitor that looked to have an issue however with my peak meter it showed it was within the limits with good very low esr values which was somewhat disappointing!
I am going to put a Meter leads across the outputs to see how stable they are when it occurs to see what they are...Last edited by cheeky2; 11-20-2024, 06:56 AM.

Thanks I thought as much but just thought it might save me some time taking the flash ic off and programming it.

Thank you Lotas
Is the Fuego 40FG4505 a USB file as well as it is only 6748kb and not 8192kb?...Last edited by cheeky2; 09-30-2024, 12:47 AM.

Looking for working dump for a PROSCAN PLEDED4022-UK with mainboard TP.SIS231.PT851 with screen V390HJ5-XCPE1 or a working dump for the same screen and main board.
I have looked on the web without any success for the dump of the Proscan TV.
Any help would be appreciated. Thanks in advance.

I suggest you learn how to use google translate to put your language into English! This is an English language forum. Don't expect answers if you write in Italian....

Let me explain a little further the switches have when this fault occurs has a resistance within the switch ( call it leakage). The solution that I have found you need to physically clean contacts I use wet and dry sand paper first inside the switch (replace the switches if you wish however finding suitable dimensions for them can be tricky to find). As good measure I then use electrical contact cleaner inside the switch. Reassemble the switch and on to the next one. All of them must be done to prevent any reoccurrences.
I have found it is very tricky to determine which of the switches...

It's certainly not static electricity that Davi.p suggests! It is not a touch sensitive board but a switch button board BN41-00989A As Lotas has stated it's the buttons leaking continuity. I have done this repair on this board many times before. You can carefully disassemble the buttons and clean them with WD40 or equivalent Contact Cleaner spray, I usually clean the contacts with wet and dry inside the switch and on the round contact inside. Be patient taking apart all of the contact switches with a small flat bladed screwdriver. If your not capable replace the BN41-00989A or just remove it from...

I agree the yellow plastic part needs to come apart from the main red part. I have looked carefully inside the battery compartment to see if there are any screws that would allow removal, unfortunately nothing obvious as you can see!
I have also removed the black cap on the front of the unit to see if there was any screws under that. No joy there either.
The whole you refer to is only a plastic cutout to allow the black probe to be stored inside as pictured in the last couple of images. There are no screw holes there either or blanking pieces!...Last edited by cheeky2; 06-05-2024, 03:47 AM.
