Re: Lg 42" plasma model p2pc3d-ud
Very interested to find out, I still have my 42V7 with this problem. Also now have a 50X3 with IPM failure on the YSUS, was thinking of getting one and recapping it but wondering if I'll get the same problem, where I used to work we got a lot of these panels with maldischarge and they replaced the entire assembly as they were under warranty, also because the service module was more reliable and used discrete circuitry rather than IPM's
Interested to see if this can be fixed, and also if anyone has a YPPD-J015C IPM going cheap.Comment

Re: Lg 42" plasma model p2pc3d-ud
I have a 42PC3D-UD with what started out as a blown Y-sus, and 4 blown 10v caps on the power board.
I replaced the caps, and replaced the IPM in the Y-sus.
I got the set to turn on for about 5 minutes, it had a buzzing sound, which steadily grew louder. I turned the TV off, unplugged the Z-board.
When I turned it on for the second time it was only a minute or so before a loud CRACKfive seconds later another loud crack... I believe the new IPM was destroyed. What a shame.
But what caused it? I still haven't figured that out. :?: I used thermal paste instead of silicon, but I doubt that had anything to do with it.
If anyone reading this has a dead Y-sus board for 42PC3D-UD. I'd be interested in buying it.
I'm going to try again, replacing an IPM on a dead one. (bought two new modules in case the Z-sus needed one). And I'm not going to risk it in the same problematic Y board.
Compatible Y-sustain boards include:
6871QYH053b
6871QYH053a
6871QYH105b
6871QYH056b
Or any other board with the same form factor will have PART NO: 6870QYH005B printed on the board.
Please reply if you have one, thanks!Comment

Re: Lg 42" plasma model p2pc3d-ud
I tried to program the board with the capacitor still missing, it seemed to program it. I got the 3 light with the 4 AAA batteries connected to it. [5.16V]
Only thing unusual was model of the board is two models.
Below is the version of the board
Model version 42V8&X3
New version 42X3_3DCS4 I installed this one..wonder if this is ok? Did not show an error, but wonder if I should have tried to load a 42V8 file?
42V8_4CS01 I can try this one later.
I will not know if this worked until I get the capacitor installed.
Any comments will be welcomed.

Hi, did you try this? Did it work?

I've done a few now, and aside from very poor PCB quality, the flash chip and be removed, flashed standalone, and refitted - it it does (largly) resolve the maldischarge problem on X3's.
I've had less success with V7's...

Re: Lg 42" plasma model p2pc3d-ud
I was looking at buying one of these from eBay. Does anyone have experience with them? Does it appear that the connectors included would facilitate firmware updates without removing the chip from the board?

I went ahead and purchased the LG jig. It's on backorder and has to be built by LG - takes around 2 to 4 weeks. If this all works out, I may offer a service.Comment

Re: Lg 42" plasma model p2pc3d-ud
I would still like to know where you get the files to upgrade the chip with. Capkid, did you order your jig from MCM? Keep us updated. I've heard mixed reviews on firmware upgrades solving the sparklies problem, but I have one I would like to try and fix.Comment

I just got an update on my order yesterday: The jig should arrive at the vendor around Dec. 14th. Also, I just subscribed to this thread, and I'll try to keep everyone posted.Comment

Re: Lg 42" plasma model p2pc3d-ud
I haven't gone so far as to locate the firmware; I figure I'll hunt it down somewhere. I ordered the jig here: http://www.appliancepartspros.com/lg...ap5592589.html

Re: Lg 42" plasma model p2pc3d-ud
I thought I had a successful outcome after adjusting the voltages then flashing the control board, but I'm seeing sparkles again. I need to investigate further.
Edit: Ok, it seems to be stable now after I readjusted the VS voltage back down to 186 from 186.9, but I'm not sure I trust it to stay there.
Here's where I started yesterday on my Toshiba 42HP66 and the adjustments I made. According to the manual, the adjustments must be made using a full white screen (raster). On the Toshiba, I chose Menu --> Setup --> White:
Power supply: Starting voltage was 187.1V - adjusted to 186V, Va voltage was fine at 60V
Vy on YSus: Starting voltage was about -180V - adjusted to -199.9V
V Setup using oscilloscope: Adjusted to approx 149V
V Set-Down using oscilloscope: No adjustment needed
ZBias on ZSus: Starting voltage was 99.6 - adjusted to 99.9V
I then flashed the control board - see before and after pics.Last edited by capkid; 12-23-2012, 02:48 PM.Comment

To add: I'm still playing with a Zenith TV with a 42V7 panel, but I'm not sure it's going to work out.Last edited by capkid; 12-23-2012, 05:05 PM.Comment

Re: Lg 42" plasma model p2pc3d-ud
You can drop Vs to the point where you just begin to lose the image. This is the minimally stable point of the plasma display. Increasing it slightly beyond there might work. Typically a plasma display will emit light between 170V and 210V. Keep it below 195V for an LG PDP because of the IPMs.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.Comment

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 howardc64All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

by stecosHi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.

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.

TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... - Loading...
