Question about Televison & Video

Open Question

The t.v.'s stand-by led will light, when plugged in, but when you depress the power button it fails to turn on. I have troubleshot the board to some extent and key-in2 fails to get its proper voltages. while I understand that this is more than likely a logic gate problem, I am unable to reset the proper sections of the board if I do not know what voltage I need to send where. I also want to verify that the components are good eliminating completely the chances that it is anything else besides a logic gate in the wrong position. If you would be so helpful as to give me some advice or even just the schematic (if you have a schematic) to Sylvania model number ld320ss1. part number - uj32mxa. Serial number - j140124538. I would greatly appreciate it! thank you so much for your help and understanding with me on this problem.

SOURCE: Remote Control Doesn't Work

You could pick up an IR tester. Your local electronics hobby store should have them. Also, you sound as if you have some electronics ability, you could do a search on the net and find a electronics hobby site and build yourself a tester. This is what I did. Now, in my 27 years of electronics I have never seen a bad IR section of a remote. the most common problem is broken solder connections. remotes get dropped, tossed, stepped on, etc... Open the unit up and look for bad solder connections. They do not have to have a physical break to be bad! If they are grey instead of shiny or if you see a ring around the lead then the connection is bad. Reflow all connections and clean all contacts. I would think that will get it back to a working conditon.

I have samsung ultra slim tv, used ic tda 11105 v3/3 chip ic.The ,problem is when press stand by button the light blinking but tv not start.


The most possibility is a defective LED back lights strip. You may open the TV back cover, un-plug the cable between the main board & the power supply, supply the AC power to it, if the back lights do not light up, the problem is the LED strip, if the back lights light up, the problem is the main board.

My tv has no power?


Let's assume your post in flat panel TV's is for an LCD TV. Since your make and model is not provided, only basic info can be provided. Most LCD TV's have a stand-by power LED that is either on or comes on when the TV switches or blinks in the event of a failure. If you don't see a light when there should be one normally, then you may have a failed stand-by power supply. The stand-by power supply provides a voltage necessary to allow you to command the tv to turn on with the remote or via the power button on the tv. If the power light is normally off and normally comes on when you use the remote to turn it on but nothing happens it can still be the stand-by power supply failed. The next level of the power control is done by a small tv micro (processor) often on a board that handles audio that tells the main power supply board to turn on. To render much technical assistance you would have to know how to take voltage readings on the PSU. If there is no SB5V you either need a PSU board or there is an issue from the AC line to the PSU. It can get complicated from there depending on the failure. I assume you know the power outlet at the wall is good and the remote battery is good and you have tried the power button on the tv to eliminate a faulty remote.

42" Vizio tv. It turns on and turns right back off. It worked perfectly fine until my cat jumped on the remote and now I have no idea what's wrong with it. I think it can be fixed if anyone knows anything...


1. pull battery from remote for 10 seconds. This will force reboot of remote. test, if fail move ahead,



2. do a main reset on Tv,, pull power plug from power source,, wait 10 seconds, reconnect, turn on!, fail continue



3. ? when you turn on TV is the stand by led light amber, when you turn on LED\'s does it start to change color , but standby light is still on? if test positive with findings issue should be your motherboard or even power board but it should be Mo/Bo..

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

Open the door & remove the 8 or so allen screws. The board is simply plug and play.

Bad design - the vent is right by the board - so its subjected to moisture.

I have a digistat scr with a flashing red light and no heating there is nothing wrong with the batteries, this only occured after a poweer cut.


Try this first before condeming the unit.

1. Turn off the power supply to the Digistat SCR (receiver unit)
and leave for 5 seconds.
2. Turn on power to SCR unit and check red light is on.
3. Press override button No.2 and check the green light comes
on and boiler fires.
4. Press & hold down button No.1 (Keep depressed), then
press No.2 and keep depressed. {The Red LED light will flash
a couple of times and then it will go out}
5. Now release both the buttons – {the two LED lights should
come back on}
6. Get the Digistat+2RF/+3RF unit and stand two metres away
from the SCR unit with the Digistat+2RF/+3RF unit in your hand.
7. Remove the battery cover and fit the batteries.
8. The Red LED light on the SCR will now flash for approx. 7
seconds.
9. This confirms that the radio signal is being sent and
received.
10. The Digistat+2RF/+3RF and the SCR are now successfully
linked by a dedicated RF address.

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board
