please explain to me (i'm sure bonez will) why in BC's SX280 premade kit, you're replacing 16V 1500s with 16V 330's? I know voltage is better if its the same, but taking the capacitance down that much?

Re: less then half rule?
There is no rule.
The reduction in capacitance is only specific for VRM circuits and their controller ICs, and only applies when using a polymer capacitor with significantly lower ESR than an aluminium electrolytic.
I believe that this comes straight from the application note of the controller IC itself.
I don't know if it applies to ALL VRM ICs though or just some specific models, but I'm sure PCBONEZ can clear that part up."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
Hi,
I have a MSI Optix MPG27CQ screen to fix, only half screen is working, I found a burned chip on the right buffer board (S270DP01V00_HF_SR) but I can't read the model. Can anybody help?...04-08-2025, 05:53 AM -
I have a 65" W Box TV, model 0E-65LED4K that most of the times it is turned on, the right half of the backlights flash on and off in a split second and remain off while the other half lights up and stays on just fine. I thought it would be the LEDs, so I checked all of them and they're all good, no direct problem with any of the LEDs or any of the connections. One thing I noticed was that when I disconnected one of the LED strips from the left side (the working side) the backlights now switched and the half left side flashed and stayed off while the right side lit up and stayed on. I then...05-22-2021, 11:25 AM
