I put in 20 new caps on the power board & it works great but I can see a bunch of burnt in "no signal" spots on the screen when screen is darker.
Do you know of a way this can be fixed? Thanks

Re: LG 50PC1DR Burn In - Help Needed
Have you checked the voltages to the label on the back of the panel, Va, Vsc, Vs, etc? -
Re: LG 50PC1DR Burn In - Help Needed
Yes, if the "no signal" leaves image retention then it is not burn in and it is fixable by adjusting the panel voltages closer to specification, in most cases.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection... -
Eventually discovered a burn mark near lower corner of LCD. Here is a summary- Backlight on, no image
- Disconnect right buffer board (view from front), left side display comes on
- Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
- Buffer board is pretty simple

Hello all!
Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .
I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next.... -
Schematic needed (and boardview if available).
Thanks. -
