I have had this as a monitor. How do I change it back to TV mode?

A flat panel TV that has these symptoms usually has power supply trouble

A 15 inch LCD is not likely to be economical to fix, shine a flashlight in a darkened room and look to see if you have a faint image on the screen.

Try to turn it on with a remote if one is available. If you don't have the original remote you can look up the universal code for the cable or satellite remote. Also try to turn it on with the input source(vcr,video game, cable box,etc...) on first. I have the same TV and if it has no signal prior to manual power up it will go to standby mode.

There are two capacitors on the inverter board that will appear slightly puffy on top. Replace both of them. You might also have to replace a surface mount fuse on the other side of the same board. This should fix any backlight or pending problems.

The caps were standard 150uF 25v electrolytic radial leads Digikey 493-1822-ND
The fuse was ridiculously tiny, a pain to solder 2.5A 32v fast 1206 Digikey F1464CT-ND
Thanks again to Badavis who posted the solution- I wouldn't have even tried fixing it without that.

first get a wall mount kit. ikea sells them cheaply.

there should be 4 screw holes on the back of the screen. screws goes in there.

first drill 2 holes on the wall
mount the ikea kit using expanding bolt
then screw in the ikea kit on the monitor
just hang the monitor on the wall side.


but..... 15 inch is a bit smallish for wall mount... dont ya think?

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you keep turning it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for a while and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

The third link most closely approximates your situation, so I made it a clickable link for you.
As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Its a hardware problem as it seems from the symptoms. Anyway it is not possible to say exactly where the problem lies without inspecting . So it would be better if you take it for repair. If that is not possible ,sell it as scrap and go for a new one.

Hi.

Re:"appeared to have a small star shaped shatter mark appear on screen": that is a damaged LCD screen , there is nothing that can be done about that , problem may get worse in time.

Re:and a four inch white rectangular shaped image without a picture.

Try connecting a DVD to the TV and check if it has signal. Use the input/source selector on remote to browse source, and check the PIP or CC (picture in picture/closed caption) settings.

Listening to your story I don't think that the problem is closed caption settings, it looks like the TV has been damaged and the main controller board is malfunctioning rather than this symptoms being caused by an incorrect settings.
