Re: coby LED 2326 will not turn on
Check the power supply and see if those 3.3V and 5V are actually connected together so are all supposed to be 5V.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: coby LED 2326 will not turn on
I am still concerned about the black glue - test it with meter on ohms 200k to see if is conductive. In the same place on the back of the board there is a black patch. If the board is burnt through some of the internal traces could be destroyed.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
Selldoor, It's not conductive. It's some type of glue dark brown color. I tried to remove it with Isopropyl alcohol 70%. It didn't work at all.Comment

Re: coby LED 2326 will not turn on
Ok but what is the mark on the back = os it the same - does the glue go right through as some sort of repair?.
Next time its together can you do an overall picture to show the layout of the boards.
and where the led cable connects to.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
I took some finger nail polish remover to it and that took it off. On the back looks like its coming where the heat sink is attached. I don't think it is going through. The spots do not line up exactly . On the front of the board looked like it was a drip. There were a few other spots on the board that had dripsComment

Thanks
U3 3251 R64 11051 is a Bit 3251 - you should have spotted that its in the thread
where you posted about getting it open
Data sheet:
https://www.badcaps.net/forum/attach...9&d=1346785892
On ebay http://www.ebay.co.uk/itm/2PCS-BIT32...item3a7f0fe386
Next time its is possible can you test that link just above the socket where it says
lvds 5v. Looks like a ferrite bead or an inductor as it is L board designator just test for continuity ohms - should be nilish. Also when you can test the voltage on both sides
with respect to ground.
Perhaps PM nte hicks and ask what happened to his?Last edited by selldoor; 03-29-2013, 09:29 AM.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
No sorry above and to the right may be L58 There are 3 labels lvds3.3v
lvds5v and lvds 12v Only the 5v is populated test each side with red probe
black probe on ground.
Bit odd each side of that resistor being 7v different that may be important.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
I could not get a read on lvds5v the numbers just kept plusing higher never did stopComment

Re: coby LED 2326 will not turn on
Hmm perhaps wasnt specific enough -power off - test across it for resistance.
Power on test for voltage with respect to ground screw.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
Selldoor, I can't get a read on this resistance or volts. The numbers just keep pulsing higher or lower. but they never stop or hold on a set of numbers.Comment

Re: coby LED 2326 will not turn on
I am sorry, I understand what you say, but I dont know what that means. Perhaps it is a pulsed signal to tell something on the board the lvds is at 5 volts - perhaps budm or tom
will comment. We will just have to test something else.Please upload pictures using attachment function when ask for help on the repair

Re: coby LED 2326 will not turn on
Selldoor, I tried another meter and got these readings meter set at 200ohms reading was 01.0 both ways. Set meter to DCvolts and got a reading of .001 both ways.Comment

by brzostosHello, HP laptop model 15-EU0005NA. It does not turn on, 1 in 100 manages to turn it on then after a while it freezes/disappears/flashes, etc.
After removing the motherboard and connecting the board with RAM to the power supply, I noticed that at first all voltages start correctly and after a few seconds 3.3V on the PL4501 coil disappears and somewhere in this area something starts beeping on the board, sometimes after touching it with a finger in the area of PL4551 it stops beeping and 3.3V appears again.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

by m1ch43lzmHi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
by HakuuHi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
by jb_BakHey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.
Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
Power Board Connector that goes to Main board
CN6401
Pin 01 NC
Pin 02 NC
Pin 03 "BL_ON": 0V
Pin 04 "N/C"
Pin 05 "STBY 3.3V": 3.5V
Pin 06 "GND": N/C
Pin 07 "AC_OFF"... - Loading...
