Question about Samsung HLN4365W 43" Rear Projection HDTV-Ready Television

1 Answer

Loss of Power

After the TV has been on 10 or 15 minutes, it just turns off. It will not come back on right away, you have to wait a few minutes. After you turn it back on it will only stay on another 10 or 15 minutes before the power goes out again. The problem seems to be getting worse.

You might want to unlpug the powercord for the night, then plug it back in the next morning. Some times that can help reset things. If that still doesnt do the trick, you might have a faulty power cord. If it does this with every source you hook up to your TV then that would be a sign that its something in the set vs. your external source.

I have a Haier TV 55DA5550 It does not turn on sometimes unless you unplug from power for a few minutes

start by trying to reset your TV. Disconnect the power cord from the outlet, then press and hold the power button on the TV (not the remote), for at least 10 seconds. Then wait a few minutes and plug the TV back in and press power once. 2 blinks on Samsung TV's usually indicates a bad power supply.

We have a NS-LTDVD 39-09 flat screen tv. Try to turn on and it trys but goes blank right away and turns back off.

Unplug it from power completely. Wait 15 minutes and plug it back in. If it still does it, you'll probably have to have the power supply replaced.

When I go to turn on my Vizio 32' Model VP322 HDTV10A, it half turns on then back off, repeatedly for 3 minutes before turning on. How can I fix this problem?

If you are not able to hear sound during the this process, the power supply of the TV is likely failing.

If you are able to hear sound during the 3 minute ordeal, then likely the inverter for the backlight is failing, which can also be caused by a failing lamp as well.

Try this: turn the TV on, wait for it to do its thing. Goto the menus, picture settings, and turn the brightness *down* as far as it will go. Exit out of the menu (save if prompted). Turn the TV off, wait a bit, then back on. If still same issue, it could be the power supply or inverter / lamp assembly. But, if the cycle is shorter, or comes on right away, then it is likely the lamp / inverter.

Loss of picture

Yes, it is the projector.
Take the filter out and vaccum it, take the lamp out and use compressed air to clean the dust away.
Be carefull witt the air thoug! keep it a bit away from the projector when u cleand the dust away, to close and you can make big mamages inside it.
And, remeber to keep the filter as cleas as possible, i clean min every 2,5-3 monthes.

Good luck

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.
