Long Time To Turn On (not the caps!) UN65MU6300FXZC
I am fixing a t.v for a friend and came across a new issue.
When powered up the backlights and sound will come on but no picture. After a few minutes the picture will come on but the turn off again shortly after.
Model: Samsung UN65MU6300FXZC
I checked all the caps on the power supply with an esr and they were all ok. I did find the thermal paste on the processor rock hard and have cleaned and reapplied.
Thanks for the help... -
Re: Toshiba 58L1350UC LED Flicker
Just checked and it was pretty stable. Maybe the brightness was down in the settings. I'll replace the led when it comes in and keep everyone updated. Any website recommendations to order individual leds?...Last edited by Choons2091; 02-10-2021, 07:23 PM.Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
Thanks Budm. I read your troubleshooting guide - very informative! On my LED strips (23 6V leds per strip) I have 120V on positive and 20 volts on negative but they dont turn on. Any ideas?...Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
OK so i just checked and it is very difficult to make out. It's either one large square led but I think its 2 small rectangles. On my original post I attached a picture of the led under a microscope....Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
I attached the only other label which was on the back of the string. Sounds good Diah i will rework them. What makes you think they are 1 watt instead of 2?...Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
Uploaded request! I used a power source to test a good led and achieved a good brightness at 6V. I know this is not a very accurate way to do it.... Open to suggestions.
Size is .118 X .118"" or 3mm X 3mm
Height: 0.020"" (0.52mm)...Last edited by Choons2091; 02-07-2021, 05:52 PM.Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
Alrighty thanks for the tip. One more thing, how do you know what the correct led is to order? I now know to get it with a diode and using a power supply i determined it is in the 6V range but how about watts?Leave a comment:

Re: Toshiba 58L1350UC LED Flicker
Hello! All new led's are like that so I must have bought the wrong ones. Thanks I didnt know they had a zener diode in them. Is there a way for me to bypass the new led's to test if that is whats causing the back lights to flicker for a second then turn off?
Also what does "TV BL" mean?...Leave a comment:

Toshiba 58L1350UC LED Flicker
Hi Folks,
First day and first post on Bad Caps so I apologize if I am missing some info or have formatting issues.
I picked up this Toshiba Tv for free off kijiji and am trying to get it working again. When plugged in the On indicator goes green then there is a 1 second flicker of the LED's. I found a couple bad LED's on the bottom row and replaced them individually however the issue persists. When using diode mode all the led's faintly turn on but when my leads are reversed THE ONES THAT HAVE BEEN REPLACED SHOW OL while old ones give .75
These are the led's I ordered....Last edited by Choons2091; 02-07-2021, 03:50 PM. -
Re: New Members - please post your introductions here
Choonie 26 from Ontario Canada. Hello Badcaps my favourite hobby is repairing electronics although I am fairly new. I regularly pick up broken electronics from kijiji or facebook marketplace just so I can diagnose and hopefully fix them for fun (and for beer money). So far I have been able to repair tv's, xbox's, playstations, dyson vacuum cleaner, computers and so on. I am happy to help with common and simple repairs and will need help myself with failures I have never seen before. CheersLeave a comment:
