Question about Samsung HCL4715W 47" Rear Projection Television

3 Answers

My Samsung TV won't turn on. What is the problem?

Everytime i plug in my Samsung 47"TV, the screen wont go on and there is a click every 5 seconds or so with a constant chirping, almost like a bird. Is it an easy fix? and would I be able to try a few things out before having to spend $1000 on a new one. Model: HCL4715W, 1080i, 480p

    I have the same problem. I have a formal electronics background but I don't have any schematics. Thus far I've just been searching the power supply for shorts with out success. If you are familiar with this TV, could you point me in the right direction? Thanks

The clicking is caused by bad capacitors on the mainboard. It is a known problem that is pretty easy to fix. I have never soldered before and I was able to fix it for about 6 bucks! If you take off the back cover (about 18 screws) the mainboard is right in the middle and in the top right corner are 4 capacitors. They are in a row from top on down. Check to see if any of them are bulged on top and if they are they are bad. All you have to do is go to radio shack and get 10u35 volt capacitors and solder them in to replace the bulged ones. The ones that came with the set are under powered and these will fix the problem. Most people are quoted about $500 or more to fix this when a little work on our own works wonders!! If anyone wants more info I am on facebook! Brian Miller in Wisconsin!

Hello tom3826,

This is a sign that the horizontal output transistor has shorted to ground, and the shutdown circuit is detecting a high current event. If you have a background in electronics, you might be able to replace this component, with the aid of a multimeter, de-soldering tools and a schematic of the TV. If you do not have a background in electronics, I would suggest that you have a qualified TV technician work on your television set. The section in question is the Horizontal/High Voltage Power section.

I hope this helps,

Thank you,

My Samsung 47 has a black film covering 1/2 the screen for about

Samsung only makes TVs that last 2 years, mine also has the same problem. Throw it away and buy a cheaper disposable TV, despite all the hype Samsung is just another cheap and nasty manufacturer who uses its customers as product testers. Why do you think they keep changing model numbers every week ?

When the tv shuts done does the power light blink? If so what number does it blink? That will tell me which circuit your problem is in. Notice the number of blinks then let me know. Also what is the model number of your set.
