Question about Insignia IS-LCDTV32 32 in. Television

1 Answer

Screen seems to dim and there is flickering while watching

I don't know if this went through the first time.

THe screen on our TV would flicker when you turn it on and then in about 3-5 seconds it went away and the unit worked great and is great viewing. Last night while watching the big game, the screen seemed to dim in contrast and then the screen started flickering. The flickering was not off and on, but the screen was fairly clear to watch.

    I have the same model TV, but in a 27" size. I'd like to replace the capacitors on the power supply board, but I think this board is different than the one you wrote about above, there are no E919 - 921 caps on my board. Most of my board notations start with the letters C or R, followed by numbers in the 500 range.
    I do see 4 caps labelled "+105 deg C", might these be the ones? If so, I need to know the ratings of a cap to replace them. I don't see any color coded rings, just labels like "CD286" and "CD263". Any tips?

This is both a common and fairly easy repair in this unit. Remove the back, but not all of the back needs to be removed to access the power supply area and locate the power supply board. You might find that all three E919,E920,E921 of the 35v/680uf caps in the upper left of the PS board are bowed and/or vented. Replace all three of them even if they test good...
Next, esr the remaining caps. Last one we did here in the shop there were 16 total that we replaced, many were orange in color but I don't have any notes on their value. The orange color of the cap is a lesser temp range we used 105 degree or better as replacements. Some we used a higher rated cap (higher voltage) same uf rating. Gave it a greater reliability.
Good Luck!
Bill

My LG 55LE5400 TV will not show a picture. The screen is black. I was watching a movie and it just went off.


Hi,
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.

Samsung LNT4669F Pixcels Flicker


As long as you only see these artifacts while watching certain broadcasts, the TV is fine.  If these lines are present no matter what you are watching, then you have a problem. What you are seeing is signal related and there isn't much you can do to fix that. Think of it like a scratched DVD; you will see strange things on the screen at times and many think it's the TV when it's only the signal from the device to the TV that is corrupt.
I have thought of one possible solution and this will depend on your TV's ability to slightly stretch the picture in vertical/horizontal directions.  If your TV will let you, you may be able to raise the top of the picture a cm or so to hide the flickering.  Check the TV's onscreen menu for anything to do with picture alignment.  This is nothing to do with aspect ratio though so ignore that.
