Strange vertical lines of dots started to fade in it was barely visible at first but within 3-4 days it became annoying as shown in the images. the problem effects all type of inputs even with no inputs at all still present on black screentried the hard resetback panel removed and checked all the connectors, cleaned it with motherboard cleaner, and reconnect each and checked that it’s properly connectedi only used the screen for 8 weeks just before the problem appearsi unscrewed the main board and tried to bend it a little just to see if the problem would disappear maybe it’s a bad soldering or something but nothing happened NOTED DURING INSPECTION ( Powered on ) High Temp of the heat sinks on the main boardAn untraceable noise i don’t know if it’s from the screen itself or from one of the boards ( sound like a faulty Coil or capacitor i don’t know ) even with the speakers connectors disconnected Before The Problem
The Problem
The Back By visual inspection every thing seems ok, no bad signs on capacitors, coils or any other components, no smell, burn sings or inflation , except the heat on the two heat sinks and the noise that i don’t know where it comes from.
I tried to cover the problem as best as i can, i’ll be very grateful for any help, if any more info, photos or even videos needed to help narrowing down the cause just ask, Thank You.
Hi! I would start by replacing that fuse on the yellow power supply board (it’s the cylindrical thing), as far as I know they need to be transparent and you have to be able to see the small wire inside connecting the 2 ends. They I’d check the capacitors and most other components on the powersupply using a multimeter and replace anything that seems not ok. If that doesn’t do the trick, I’d suggest replacing the motherbord (the green one).
