Tampatec , Hi I got sony led tv ex40 520 with sound but no picture ,could it be the T-con board .? Tks for your videos ,i learn alot.👍👍👍

Ng Ahseong yes most likely tcon board I think IC AS15 could be bad on tcon board. shopjimmy.com and electropartsonline.com has tv boards

Tampatec Hi, any ideas how do we get to order the exact TCON board for our tv model? How to get the part number etc..thanks:) 5:39 I accidentally took out the ribbon cable without unplugging the power cord and immediately put it back again..now there is no picture but backlight.. Moreover, vertical lines is one issue, my Samsung LED d6600 got horizontal lines on the top 1/4th section of panel. Are there any differences between two problems? Thanks..nice detailed video...keepup:)

Tampatec thanks a lot,you are a great man!👍👍👍

Tampatec Hey was up from California , great videos I have learned a lot with you , I have a JVC not sure what model but question is (is it possible for inferred on the tv to go bad ) have tried multiple remotes and nothing Thanx a lot and keep on with your great videos

Bri G. everything pretty much can be repaired by just buying new boards it's not like the old vacuum tubes ect...but excellant video content hopefully the days of extremely hi repair bills are a thing of the past but not to worry there's plenty of thrives still out here raping and pilliging, it's odd to find an honest anyone anymore.

I wouldn't call this repair knowledge - it's just swapping out parts until it works?

Sometimes more than 1 board goes bad on flat screens There are cases where 1 board will take out 2 more boards and be too expensive to repair the set They design this crap to fail after the warrantee expires. Your lucky to get 2 years use out of this new crap. The crt sets from the seventies are still going and still can be serviced without breaking the bank

Replacing the tcon would be the easiest thing ever. A lot simpler than soldering a flat flex cable.

@@jean-lucpicard5510prove it or shut up

@SLICK8116 I can prove that I did your mum last night.

Did you watch the video? Take screws out of back cover remove flat cables from board and remove screws. Then reverse order and done. Easy

Chad Kesler thanks

My screen is black should I try replacing t con board?? I have audio just no picture

Walmart has it for 12 bucks

Ok lang yan brad hehe

Workshop Manual for the TV would help with this.

I worked at a tv repair shop when I was in high school...way,way back in the "old school" 1960`s when we had to contend with horizontal output transformers and picture tubes remaining charged with thousands of volts long after the sets being turned off.....today`s HDTV`s look much less threatening to service.... :-)

Picked up this as a pass time hobby, Like to know also what voltages should be, is this standard for all tv’s. Been watching your vids for awhile now most are very informative.

I tried it and is working for me now

samsung plasma model#PN50A450P1D horizontal lines on TV can you give me a step by step on how to fix this I love technology and want to learn this Talent thank you

bad buffers on the right side of the screen or a bad screen

Hi. M UN65MU8000 has distorted colors. I seen your videos and, I think it has to do 8th Tcom board. I had a battle with Samsung on the phone. First they said it was a software problem and I didn’t have the correct one installed. So they sent me a usb drive with the ‘’Right software... I installed it, but it didn’t work. I called again and this time they sent a one connect box, but didn’t work either. I was very upset and demanded a solution and, after threatening me with charging me if a technician sent by them could found any damage on the tv, because (according to them) the warranty should be canceled, the technician visited me, took a look and confirmed how bad it was. He, then left after giving me a receipt with not much details. Samsung never called to inform about the next step. Called them a week later to find out what was going on. They apologized, but told me that the technician found scratches on the screen, so the warranty was canceled. I told them there was no bleeding so the problem didn’t have to do with that and I was not asking them to replace my tv, but fix it. They denied me further service at all.

Enjoyed all of your videos and have previously said so. I too, would like to know how you knew what the voltages should have been, in this video specifically? Thanks.

Good Evening Bro, can it work for Maxi Tv

it could possibly be your t-con board you should pick up a multimeter off amazon and test it out the same way the video showed.

My seiki flat screen only shows pic while guide is on.when I exit guide,it turns off but comes back on after a few seconds,only on guide.what can I do to fix this ?

Did you ever get an answers

vertical lines = easy fix, horizontal lines = hard expensive fix

Nothing a new display panel won't fix. Samsung plasma panels for the most part were crap.

i dont think the actual voltage is as important as the voltages being constant. But i have no real understanding

Sean Moran I’m an electronics engineer working with microcontrollers. In our field it would be vitality important to know the voltage between boards, if not the actual waveforms on an oscilloscope. This would only give you a rough idea of which boards might not be working (once you worked out the power supply was ok !).

If your table isn't grounded and you put 12V to ground, all ground points will read 12V. It can be read either way. If you ground the chassis then you are correct. Most TV repairs are done without a grounded chassis.

sanjay, Update?

Did that work for you?
