Question about Samsung HL-R7178W 71" HDTV

1 Answer

Samsung TV will turn on and off several times, then stay on.

When I turn on the Samsung LED DLP HL-S5679W and any other HDMI device, the TV will shut off, then go through several on-off sequences before finally staying on. The TV will power on by itself without a problem, but if I try to turn on my HDMI DirectTV, receiver, or DVD, the TV will start powering off and on several times. I can turn on my TV (nothing else) wait a few minutes, then turn on the DirectTV box and the TV will instantly begin the on-off sequence a few times, up to 20+ times (sometimes over 2 minutes). My components will work with another TV, its just this Samsung TV. Can anyone help?

    I have the same problem, but with time warner HD recorder. Anyone have a fix for this?

  • Anonymous Feb 16, 2009

    I'm not sure how to check the power board. The repair tech (useless), did the same troubleshooting steps I did and quoted me $795 for a new motherboard. I also checked component connection, same result, even worse. So any device hooked up with this TV will not let the TV turn on. Need help. Anyone got something?

Hi I have a Hl-s5679w led-dlp and it just started turn on and off, I have been reading online and the solution keeps coming back to under-sized capacitors, now to my question Would I be able to upgrade the...


Yes you would. On the power supply board under the heat sink. Do not upgrade the UF but you can upgrade the volts so if the caps say 10v 2200uf go to the 16v 2200uf and always make sure they are 105c degrees.

Samsung tv model# HL-S5679W all three lights on front panel blink, no pix or sound owner's manual says lamp may be defective this is a DLP-LED. No conventional single lamp


The "lamp" in this set, I think, is called the "DLP" in the parts listings. That part is number: 4719-001960 and can be purchased from tritronicsinc.com for $249.75 plus shipping. Use the guest account to access this info.

Hope this helps,

42 inch Samsung DLP TV shuts off by itself. I can turn it back on and sometimes it stays on and other times shuts off within seconds. Some days it stays on all day without a problem. Other days it shuts...


I bypassed the safety switch (it was bad) and vacuumed and blew out all of the dust. So far with this set, 3 years old, I have replaced the bulb twice,it exploded both times, and the color wheel which also exploded! We love the picture but the next time it goes out, it goes out to the trash and I will purchase a top of the line LED/LCD set. No moving parts!!! Samsung designed and manufactured a whole bunch of lemon sets and will not admit it. I have found several hundred complaints about their DLP sets and only a few on other brands.

WILL NOT POWER ON, STANDBY, LED, TIMER LIGHTS ARE BLINKING.


Check the capacitors on the power supply first. If any have domed tops or signs of leakage, replace them. I had two go bad on mine. Call electronics parts supply stores first as these are not your average capacitors.

i GOT TIRED OF FIGHTING IT, AND JUST LEAVE IT ON ALL THE TIME, SINCE MINE WILL TURN OFF CONTINUOUSLY FOR THE FIRST 3 HOURS OF TRYING TO TURN IT ON, SO BY THE TIME IT IS ABLE TO STAY ON FOR THE DURATION, YOU DON'T NEED IT ANYMORE, SO JUST LEAVING IT ALWAYS ON, IT IS READY WHEN I WANT IT. WHAT A PAIN.
