plasma tv LG model 50PS3000-ZB, Z SUS board EAX 55361501
I need schematics diagram for this board because Ihave IC402 very burnt and I can'nt read his marked is some ISR2****.Image is very dark .Thanks,from Romania

Sadly you won't find a service manual for these boards because they are not published by LG. What is the fault with your model?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -

Thanks for reply.Image is very dark sound OK.I have replace IC 402 with ISR21814, but i'm not sure if is the correct IC, because original IC is very burnt and I can'nt read the marked.Comment

Re: plasma tv LG model 50PS3000-ZB, Z SUS board EAX 55361501
That is the classic sign of a bad Z-sustain, so that board is likely at fault. Can you post a picture of the area the chip came from - it may be possible to make a guess/estimate of what component was used there.Please do not PM me with questions!

I try this, IC402 is near diode D401, right down, thanks again very much you try to help me and scuse me if my english is not too goodAttached FilesLast edited by ANDRASONI LUCIAN; 06-15-2012, 10:11 AM.Comment

Your English is better than my Romanian!
I can't really see the designations on that board - could you highlight the D401 component and the burnt IC in an image editor?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

That chip is likely a gate driver IC. Does it connect in any way to the MOSFETs on the Z-sustain board?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Yes, but i do'nt know the IC who i replace it is the correct IC , all service manuals who i find no contains Z sustain board, Ysustain board,POWER SUPPLY board and components listComment

Probably too late for the O/P, but if anyone else has the same problem it's an IRS210614SAttached FilesComment

Gidday from Downunder,
Chasing the Schematics and also the board view for the HP Laptop board, model
according to the board markings that is read sideways against the the side frame to the graphics card or the DDR4 slot it says the following for the Model,
“MODEL:OPAK”
Then assuming the card was still inserted into the slot, releasing the card and removing it will reveal the full markings printed on the board (not the card),
“DAOPAKMB6FO REV:F”
Below in smaller print is a small logo of I think a backwards R with the letter U with the left stroke of the... -
Hey 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"... -
I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.
The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.
I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was... -
Hello!
I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.
Problem
My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.
(See Attachment 1)
Self Diagnosing
After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires... -
ONN 100012588
Issue: No Power, Then Rebooting After Main Board Change
Short answer: replace main board and power board
Technical answer: replace main board and Q306 & Q307 on power board.
Long answer:
TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....
