Re: Wharfedale LTF37K1CB Picture problem
Hi all,
Well I finally managed to get those 2 Panasonic caps (what a pain that was getting only 2 and cheap - ended up paying £3.78 for the pair, even though I had found them elsewhere for about 50p each) and replaced them today. TV's been on for an hour with no drop out and have turned it on/off/on/off/on/off a few times and starts first time every time and stays on every time (not like before)
So THANK YOU to EVERYONE that helped me out and I will certainly return for any future help I may need.
Also if anyone ever needs help with iPhones please PM me

For some reason I'm just not going to let this 19" TV defeat me. I guess because I have a schematic to work from I feel like I'm oh so close.
History- while adding a turn-on circuit I let a small screw roll under the power board. Worked through all of that circuitry, probably replacing a MOSFET and PWM controller that were not bad but I was following the service manual. Finally figured out that the power supply is in working order when the inverter section (for the backlights) is disconnected. When the +12 supply to the inverter is disconnected the +12 and +5 will come up... -
Hi all,
hopefully someone on this board has an idea on how to begin with troubleshooting this problem.
The monitor AOC AGON AG273QCG (curved 27" QHD monitor) has problems refreshing every 1 to 2 seconds or so. A line appears in the middle of the screen and the lower half of the screen is shifted to the right.
See attached picture.
I am leaning towards an issue with bad soldering of the graphics chip, because the problem used to go away after some time (minutes) but now it is here to stay.
However, this could also be related...08-12-2023, 02:36 AM -
Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected... -
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
Hello gurus, hope you can assist me...
I have a Sony KDL.40P3600, with an issue on the left side of the screen (pictures attached).
I think the problem is the panel, but before send it to trash, i would like to get a second opinion.
Thanks in advance.
