TV KEEPS TURNING OFF AND WONT STAY 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.

Turned my TV off and now it wont come back on


Possible bad capacitors on the power supply board which is a very common issue with most LCD televisions. Just check the tops of the capacitors on the power supply board if they are puffed up on top they are bad. They should be completely flat on top.

My toshiba tv 32rv530u wont turn on


Replace the damaged capacitor and check first. If it do not help you, replace the power supply regulator board as card. It will be best, rather than trying to make the present one get repaired.

When i turn off tv it wont go back on for hours


The most likely issue is your power supply is failing. Most likely issue that would cause this problem is bad capacitors on the power supply.
What happens in the above situation is:
After the Tv has been off for some time the electronics and capacitors are cool and supply the correct voltage so the TV turns on.
After using the TV the electronics heat up and the material in the capacitors expands causing the power supply to supply incorrect voltage. With the TV the power is flowing and is close enough to the correct values for the TV to stay on, after being shut off the TV will not turn back on because correct voltage is not present until the components cool down and the voltage at power on no longer engages the protection circuit.

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!

Samsung LCD tv wont turn on


what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

pls rate me!
