Re: RUNTK 5351TP No Picture Failure
The KL5T3067 can also fail? but its a good bet that if the VCC 3.3v is missing changing the ISL9860 will do the trick, As soon as there was a good supply of new boards. I stopped repairing them, with the customer paying repair cost I just brought new.Comment

Re: RUNTK 5351TP No Picture Failure
I did read the above? I am just adding that if you do not have the VCC 3.3v the chances are its the ISL9860 that has failed or has not been fitted correctly.And not the KL5T3067 that is at faultComment

Re: RUNTK 5351TP No Picture Failure
I think I'm having the exact same issue (ReeceyBurger just replied to my own thread just a few minutes ago - cheers
). I think I'll try measuring VCC 3.3 first with and without the buffers attached. If I get nothing, the ISL driver is most likely busted.
From what I read on the forum the other chap linked to (I fortunately speak native Romanian) I should also take readings of VGH and VGL, though I'm not entirely sure what they should normally read. Lots of info here, so hopefully I'll manage to pull though
EDIT: upon reading the Romanian forum thread more carefully, I noticed VGH and VGL should be around 35v and -6v respectively (or real close to that)...is this correct ? The fellow over there didn't have T-con issues after all, so I can trust those readings to be pretty close to what they should normally be - it was a shorted driver on the right side of the screen which dragged down the VGH bus.Wattevah...Comment

Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.
I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...10-15-2025, 01:53 AM -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and...
