Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

TV keeps turning off.

The time of tv powered varies. Maybe about 15 - 25 mins. When the tv is turn on for the first time, last longer, maybe about 35-40 min, then it turns off and keeps doing it every 15-20 mins. The center light flash like two or three times. And do the same when I try to turn the tv on.

Could be a couple of things
first i would guess to be convergance ic then IC831S (STR-X6456).and could be loose connection.
you could try this to narrow it down, purchase a can of freeze at radio shock and spray it on these ic one at a time see if it stays on longer or just replace them

When tv is turn off and goes to standby it does not have picture when turned back on with remote or tv on off button. the set is 1.5 yers from purchase. what can i do to fix


the low voltage side is weak there is a 5 volt side on the main power this is where standby is and also is used for startup, it sends power to the startup switch if its to low even just by a few volts it may not have the power to turn on the tv fully and take longer for the screen to come on. on the power board check the capacitors there are a few 16v and one or 2 6.5volt types theses maybe weak. if you replace them. they also like to put inferia capacitors in the power board so that it will need repairing so buy a good brand 105c type black or gold type these last far longer and even out the power consumption in the board.

What do I do when my Emerson TV keeps turning off by itself?


This is probably due to dry solders in the power supply area of the tv... next time when it powers off give it a whack on the side and see if will just light up for a moment.. If it doesn't just open the tv and check for dry solders, loose contacts and faulty capacitors.. PS:I would not task some one without experience in electronics to handle this one. This shouldn't cost you much even if you hire a tech anyway..

Tv turns on by itself


Pull batteries out of the remote control and keep it that way, just to see if maybe power button on remote control is being pressed/faulty. Also check the auto turn-on option of your TV, it might be set to a specific time to power on/off. This would be noticable if TV is powering on at specific time of day.

My tv cuts off then it won't come back on when powered on the power button light just keeps flashing. After unplugging tv for 20-25 mins it will come back on


CRT screens use a vacuum tubes for displaying purposes. These tubes warn off through time and use, with symptoms like colours fading out, late responce on start and even quit doing what they suppose to do.
My solution is to replace the warn tube with a new one,if you really want to keep this screen properly functional, but this could get to much trouble and cost maybe.

T.v will not turn on


Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, it maybe something simple like a blown fuse inside the TV. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Projection TV turns off for a few seconds


Good Day, boattech1;
To my understanding the Model 53UDX10B is a rear projection, that uses no fans. I think maybe your LAMP may be getting weak.
Good Luck, big IRISH.

TV CUTTING OFF


Check this, for how long the TV is on? 30 min., 45min, 1 hour? because maybe you have accidentally programmed the SLEEP control. If so, go to the set up options or menu with the remote control and check the status of the sleep power off time. Or maybe the TV has the otion to power off automaticly set the same way that is the alarm turn on.
