SOURCE: Tv shuts off

I had the same symptoms. I replaced the lamp and fixed the problem. But then I looked at the old lamp. There was a dust buildup on the screens which cover the cooling holes. I blew off the dust and put the old lamp back in- it worked fine!

Check out the fixYa solution for the Samsung LNS4051D- it sounds like the same problem. Defective capacitors. You may need different part though.  We just fixed my mom's LNS4051D with that problem. I have the LNT4665 and although it hasn't failed yet, I am tempted to get some capacitors just in case.

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at just leave them a email they respond quickly.

This could be either the lamp or ballast. I'd check the lamp first. If you've never replaced it, 5 years is a HELL of a long time for a lamp... when you replace it, you'll notice a brighter picture too. Sony uses Philips, so only buy Philips from an authorized agent. Make sure the date codes are new too, because you don't want old stock lamps.

Samsung LED UN65f7050 stopped working. gives repeating blink code error code of 5 pairs relay click at plug in followed by a second click a 2-4 sec. later. No pic, no sound power supply?

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Works for 5 seconds

This sounds like a power problem .. It may have a switch mode power supply... turn it on and listen if you can hear a faint clicking sound ... maybe the switchmode power supply is not switching on properly.

Toshiba Color TV Relay clicks slowly. TV does not come ON.

Electrolitic Capasitors in the power supply going or being bad will cause this. At some point a low value resister also will start to run hot or burn up. I believe it it a 16v 1500 uf cap near the relay. I would also replace any 10uf 160v caps in the powersupply too.
Hope this Helps,

Power to Amp but no lights and does not switch on

(1)When the unit is switched on the relay clicks in,but no sign of life, and then five seconds later the second relay clicks on/off don't know which. This symptom is DC outputted to speaker terminals. Check any DC at power amp stage output.(2)Must have blown up.
Positive. If Caps blew, your amp shutted itself down within 5 seconds due to + & - power supply creating an unbalanced +B & - B voltage not allowing your amp to turn on.

Will not power up

your problem is in flyback or high voltage section failure.

  • check horizontal output transistor
  • check fly back transformer.
  • check for supply to horizontal section as high voltage from power supply may create such problem
  • as this failure is due high voltage section so it is better to take skilled technician help.
  • good luck.

Sony Big Screen TV Not Powering On

This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,
