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 www.tvrepairworld.com just leave them a email they respond quickly.

SOURCE: TV TURNS OFF ITSELF AND 15 SECOND LATER IT COMES

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.

Okay, so my Panasonic PT-43LC14 went black in mid show last night. The bulb is approximately 18 months old. The LED indicators upon Power On are; Power LED blinks green for approximately 70 seconds; Then...


Check the bulb again and look at the root of where the main stem comes out inside and be sure you don't see any bubble like appearence around the stem at the bottom there. If you do see this then the bulb is bad. Otherwise try this: Hold volume down on front of unit and pip on remote for about 5 seconds. Message will come on screen that timer has been reset to zero. This sets the lamp timer to 0

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Hi, the relay is getting a command to shut down because there is a short somewhere in the set, if you have a volt meter you can check the "chemical fuses" to see which one(s) are open and that will tell me which circuit has the short in it. be advised these are not glass fuses so if your unfamiliar with what a chemical fuse looks like you will have to look on the power supply board for a small rectangular body device with a designation printed on the board "Fxxx". check these and let me know which ones you have failed and we can go from there, BMW Rider

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,
