I've got a couple of vertical line that goes from the bottom to the middle of the screen. According to the Service Manual it could be coming from the D board ( control board) or the C5 ( data driver board) which control the lower center of the screen. My question is how can I determine which board it is or do I just replace. I think with my knowledge I can change out the D board but the C5 board i'm a little intimidated with the connectors going to the plasma screen. Any help and advice would be greatly appreciated.

Re: Panasonic Th-50pz700u Vertical Line
How thick is the line? Just a few pixels or an inch or more?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic Th-50pz700u Vertical Line
It looks like about 4 lines. Each are as thick as a pixel. One a greenish color another is yellow, sometimes you see a purple tint and some a couple of very faint tan/white lines. It's on all inputs if that matters.Comment

Re: Panasonic Th-50pz700u Vertical Line
Unfortunately that line is an unrepairable panel fault

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I 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.

Hi, 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... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
My old plasma died when one night recently. When I got to it it was giving a 3.3v sos (3 blinks).
I chased my way through the PSU, and a board, with no results.
Replacing a few bulged caps in the PSU, I eventually got to the SC board that had piles of shorts, a quick cheap replacement from china and the tv powers up again, except
I only have the right half of the picture.
Left half is completely blank.
now the c3 board running this side of the screen has its 3.3 and 5v onto the buffer ic and its got the 60v, so that all seems good.
all the other voltage rails...09-24-2024, 04:39 AM
