SOURCE: Bottom half of the screen is black on Samsung HP-R5072 50 in. HDTV Plasma Television

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

SOURCE: my tv turns off by itself and makes a clicking noise

Most likely it has some bad capacitors in the power supply. Flat--panel sets are VERY hard on capacitors, due to the fact that the "rising heat' from the set "cooks" the caps and they fail VERY early.

05 cts when iturn the key the engine does not stat just a click 2 or 3 times the it starts and it does not sound healthy( im from winnipeg minus 25 don't plug car in) when it warms up it does strt fine...


If it's the original battery, it's 12 years old and way beyond it's useful life. If replaced once, the second battery is probably near the end of its life, five to six years

If you're near a Wal-Mart super store, get a new battery installed if the other is old, five to six years They have good prices and top rated batteries by CR. While you're there and if it's -25 (C or F since the scales are concurrent about that point) go to snack shop and warm up with a nice hot cocoa or hot cup of coffee. Sometimes its free in the customer lounge.

Good Luck

Samsung TV...Turn on tv, it operates for maybe a minute, then shuts itself off and has a consistant clicking pattern, like a relay switch. Sometimes turns itself back on


Not knowing the specific model for your Samsung TV and how old it is, I can only offer this possibility because I've encountered what sounds like the same problem. Certain models of Samsung HDTVs around 3-4 years back have a design problem with their power supplies - they put in the wrong size capacitors (aka "Caps"). After a few years, the capacitors fail, and the power supply also fails. I think it's possible to replace individual capacitors, but most likely you will have to replace the power supply. Unfortunately if it's out of warranty, it will cost several hundred dollars, especially for a home / onsite visit. There is a visible symptom - from 2-6 capacitors on the power supply board will bulge out, as shown in this pic:digizen.jpg
You might try calling Samsung customer service and tell them you are aware of problems with their power supply design, and try to get them to repair the TV for free, especially if you are just out of warranty.

At just over 1 year old and out of warranty, my Samsung 52'' LCD will not turn on. You can hear the relay click on/off/on/off, getting slower, until it will turn on after about 8 minutes. The firmware has...


Same problem on my friends Samsung LN52A650A. Never did the firmware update cause that refers to a random shut-off problem. I replaced (2) 1000 10 volt caps next to a heat sink with 1000s rated at 35 volts @105 degrees C. The tops on his were a little swollen and you had to really look close. The caps were 2 0f 4 inline caps. They were the smaller 2. TV works.

Sunbeam SLP3310-UM shuts off after 2 minutes. I unplug it and hear a relay clicking after a couple of minutes. Replug it, and shuts off again after 2 minutes. It worked fine last year, not this year.


It's broken --- call Sunbeam customer service (888) 264-9669 and have your receipt and serial number ready. They are aware that these have faulty switches in them.

When i turn on my samsung projection tv, the LAMP, TIMER, and STANDBY indicators light up and the TV Shuts off after a couple minutes. Not sure what is causing the problem. TV is 2 years old


Hi,do you hear clicking or like wanting to turn on? If you do it could be an issue with the ballast which is the board that powers the lamp.It sounds like the lamp because they normally last 2-4 yrs and when its bad you'll get 3 led indicators and will shut off every few seconds.Make sure you get the Original Philips lamp you can find it on discount-merchant.God bless you!

Samsung HL-r5667w TV shuts down on its own.


You may have a colorwheel going bad. The bearings start going out and this is an indication of the failure. The colorwheel is located in the light engin e therefore you may want to get a qualified tech to look at it
