Samsung PN58C8000 Plasma. Picture changes from full color to a blue tinted picture. Logic board replaced 2yrs ago when TV would not turn on. Inspected all boards, no swollen capacitors.


Hi T Quinn.
Does the TV behaves the same way in all the inputs?
Does the color chances when the TV has been on for a while?
This failure could be in the main board, all the video info gets into the logic board from the main board itself.
I would suggest to check for proper voltages from the power supply to the main board, if all the voltages measure as expected. I would suggest to use a small cooling fan and place it near the main board.
Let me know if you require further assistance..

Hi i have a 42 baird tv the light is on red goes green but i have no picture.could u please tell me why


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

VO37L HDTV10A backlight on, get sound, no picture


TV sets that have been exposed to significant surges can have multiple boards that are damaged. If the backlights are indeed firing, and you get no picture, you may have a problem with the T-Con board, assuming the main board is working properly. This is exactly why I steer people away from repairing sets that have been hit with large surges. In most cases it will be cheaper to buy new sets vs. repair them.

I have two Panasonic PT-LB10VU projectors doing the same thing. They project find with RGB, but when trying to project a VHS tape through video, the image rolls or has multiple lines running through it. ...


first of all you replace the present video driver VHS tape and try any other dvd driver or any other video device if problem exist then the main board of you projector is faulty.

Solution: open the upper over remove 5 screw back side of projector.
disconnect the panel ribbon cable.Remove lamp cover with 3 screw remove main board with 4 screw and 8 connector. put it face down on a table and use a table lamp for more light.
check very carefully the area I show in the picture with red arrow there is a resistor no.R041(on resistor 750) is burn out or black replace witch 75ohm resistor and check around the resistor if burn any other component replace with the same after repair of main board fix the all part of projector as you open. Power on and use any video device other than your VHS tape maybe the high voltage comes on video output.
if fault exist then need to be replaced the main board. good_help_11.jpg

AKAI Plasma TV PDP5016H


See I cant cross that part number and I have all the boards sitting in front of me. That number is the akai part number, but not the actual number of the board. There are 2 boards that they call main in the service manual, the main control board which actually drives the panal, and the "main video board" which handels the video inputs and on screen displays.

PCB failure analysis
1. MAIN CONTROL : a. Abnormal noise on screen. b. No picture.
2. MAIN (video): a. Lacking color, Bad color scale.
b. No voice.
c. No picture but with signals output, OSD
and back light.

If you can determine which of the 2 boards is the problem, I can sell you a new replacement for $125 shipped.

Basicall....Control board is no picture at all.

Main board is no picture, but on screen displays work.
