My coby flatscreen comes on and works but strobes flashing light but works good just with strobing light ! whats going on?


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Flickering Sanyo LCD TV


There is some dry solder/leaky or dry capacitor in the board. I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

No temperature digital display in refrigerator, light working, but loosing temperature in fridge & freezer


if its a G.E. make first check the PTC overload on the compressor to make sure compreesor is operating, if this isnt,check voltages on ptc,if no line voltage here,then check for the motherboard in the rear behind a panel as this board when bad will make digital readout go out and lights strobe and you may hear a clicking noise from there also as the lights flicker or strobe this board failure can be caused from a surge within the unit by a light bulb burning out or a power surge from outside too

FLICKERING BACK LIGHT


Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.

Vizio television screen flickers like a strobe light


lcd sets use florescent tubes to light the display and, a ballast to power the tubes just like the lights in an office ceiling.
the tubes are called cold cathodes and, the ballasts are called inverter boards. replace your inverter circuit board it connects by wires to the cold cathodes so; isn't hard to find.

Voltages do not dance around and should be constant and within stated parameters.. The board producing those crazy readings is the issue.
