    red stand by light stays on whenever i push the power button on the remote or tv, BUT, if i unplug the set and plug it back in it will work (red light turns green when I push the power button) BUT, now it no longer does. Unplugging and plugging it back in worked for about a month until today.

This is probably due to damaged inverter board. The best thing to do will be to get a replacement part from sears or somewhere else. Also if you can get me the part number i can help you find a replacement online.. Just in case..

It is the power supply. Replace the C97, C19, and C16 Capacitors with 2.2 uF ones.

A job for the technician on this one. I have only worked on several flat screen before, on my last days as an electronic technicians. Half of the ones I worked on was the power supply inside ir the problem was like this. Instruction on how to fix them would require me to write many pages on electronic theory so, I am very sorry It is almost impossible for me to help you on that. Be carefull where you take that tv to. some shop can't fix those. You may have to search your local area for someone who specialize in flat sreen HDTV. Well I hope I have shed a little light on the problem. Thanx for posting the problem.

SOURCE: The tv will not turn on with either the remote or

Hi, I own the same TV and had the same problem. It's the #1 plaguing issue with flat panel TV made by Funai corp. Emerson is made by them. Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board.

The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can'tactually look at the tv over the internet. I can only make guesses with the symptom. I'm willing to bet you have the same problem like mine. One of six Inverter Transformers when bad on my Power/Backlight Inverter Supply Board. I replaced it and it works fine again.

You have a few choices:

1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.


2. If by chance the TV is still under warranty, go that route.


3. If you have some electronic experience, if you can find and purchase a Service Manual at Tvtechcenter.com; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $6. And most cases the new part cost less than $15. The service manual at the site is under LC320EM82S.


4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Nec pxt-42sx1b won't turn on. We press the on button on the remote and the stand by light turns from red to blue but then goes back to standby.


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

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.3_26_2012_10_39_22_pm.jpg

TV won't turn on. flashes a series of 5 red lights instead of turning green


Usually Sony and LG Blinking Codes are the same. Here is what I have.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.
  • Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

My 40' vivo tv has turned off and won't turn back on but the red stand by light is on??


If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

Stuck in standby


Sorry about that. When the tv goes bad like not turning on, the green light will blink, and goes right back to red standby light while the dtv letters will briefly show on the lower right of the tv screen, then go back to blank screen. The tv will need to be taken to an authorized service center for repair. Common causes are a bad inverter/power supply, power control board, or circuit board.

Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.
