You could very well have poor solder connections.

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

Tv turns on and off all by itself, all day long. picture is still perfect when it stays on long enough.


Good day..


That problem is usually cause of bad capacitors on the power supply section..

As you stated your TV works fine and after a minute the red light comes on...

That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..

This is the sample picture of bulged capacitors:

I keep getting a blank blue screen when I turn on my Mitsubishi 60 inch TV and then turns off by itself after about a minute. When I press "pip" on my TV remote I can see a small square screen...


there are 2 tuners in a rear projection tv. maybe the main tuner is faulty or the tuner's associated circuit has problem. if there is no signal these tv are programmed to turn the power off/stand by.

Sony KDF-46E2000 - Screen Goes Blank


The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.
