It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

There is no such button. Just unplug the set from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset.

something clearly is wrong which is why it shuts off:

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as . Or just click here to see more details on their kit.

  • If your DirecTV box supports HDTV then connect it using either an HDMI cable from the box to the TV (located on the back, labeled HDMI 1,2,3,etc.).
  • If the box is not an HDTV box then connect it with a RGB (red, green, blue) composite cable from the box to the TV.
  • If the RGB output is not on the ack of the box then connect using a standard coaxial cable.

[NOTE] In order for the quality of the picture to be HD, use the RGB for digital (Better), or the HDMI for High-def (Best)

That is an error code of sorts for that brand - I'd open it up and check the power supply for bad capacitors - leaking at the top or bottom - bulged at the top etc - replace them or the power supply and go from there.

You need to find out mare as to what else that the repair shop left out, all the coonectors need to be checked to see if they are in correct place, beside missing the SPEAKER board, no other boards are missing? I would go back and have them put all the old boards back inplace, he may have takebn out the inverter board and others to use for other repair jobs.
You may need the service manual to figure out.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Basic LCD monitor and TV troubleshooting guide:
Failed TV and Monitors:
Learn about bad caps:
Capacitors kit: he can make you a set of caps.
Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.
Please leave rating if it helps.
