Re: LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

Hello tingshen, I subscribe to this thread but not sure why it hadn't sent me update emails when you posted. I also havent visited hardwarezone for a while and just logged in today. Sorry about that. Glad you found Tom though. How is it so far? Maybe you want to respond to Tom's query or share what you've done since.

Hey Tom

Report back that not only is my TV still working fine, a second TV was also fixed as a result of Tom's excellent advice!

That 2nd TV belongs to the friend I mentioned in first post. We didn't realise at that time that his TV is the same as mine! Freaky coincidence. So we used the same technique to isolate main board, test and replaced it. His family is so happy now.

So thank you once again Tom!

Yup was cheaper than I expected. All in, I spent only tens of dollars more than if I requested for LG's service, and certainly a lot less than a new TV. Plus I have a whole set of spare boards for future use (if no one buys them).

Now I'm extra gentle plugging in cables to the main board. In fact I leave a USB extension cable attached to avoid unnecessary physical contact with the board over USB devices.

Your support for Panasonic makes me even more certain now. Nice

Re: LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

Another update that my TV's fixed after replacing the main board!

Long version:
So unfortunately (actually, fortunately) EncompassParts and SearsParts only sell main boards to authorised service agents, while shopjimmy had no stock. I read somewhere that LG will not sell boards to customers since they are not customer serviceable parts. But in desperation, I emailed LG Singapore anyway and they replied that they have the main board at US$87, no warranty though. I picked it up right away,...

As I recall, in both cases they didn't make any difference unfortunately. Problems will be there every time I switch it on, whether cold start, or after an hour or two of troubleshooting....

That's wonderful info cos I don't use tuner since I have cable. I might have to use a forwarder to ship.

Thanks for the advice Tom!

Re: LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

just a mini update...
bad news.. shopjimmy can't accept returns after 30 days (my fault for procrastinating so long)... and my main board (EAX61744403/EBU60742922/EBT61115501) still can't be found anywhere... *sigh*

Re: LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

Yes, will do that.
Unfortunately no one seems to have my main board variation EAX61744403... should be region specific... will keep searching.

Thanks very much again Tom!

that I can do....
and I let it cycle 4 times for good measure... the tests were flawless!

[words cannot describe how much I wished I'd found this site (and tom66) _before_ I ordered all those parts... and I'd researched for days... damn you google!]

Re: LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

Thanks for the super quick responses guys. Really appreciated.

Okay I attached close up photos of control board (and main board too just in case).

When I ordered the parts from Shopjimmy.com, they didn't have the main board in stock and it alone costs over US$100, plus inputs were working so my lay self didn't suspect it......

LG 50PK950-TA shaking/flipping image (replaced 5 boards still the same)

Hello,

This is a plasma TV.

Problem:
Couple of months ago, image suddenly started juddering and flipping (left-right mirror), with horizontal streaks. Video of someone else's TV with similar problem: [url]https://www.youtube.com/watch?v=g7-YrQVXAUM[/url]
There will also be small clusters of black pixels around. Problems show even in system menu, so not input/source/cable issue. Audio is perfect.

Hardware fix attempts:
I checked the web for ideas but still uncertain so I ordered 5 parts at one go (cost ~US$210 shipped). Replaced each piece...
