North Charleston: I have a fine-looking 32" Samsung LN-S3251D I got out of the dumpster at an apartment. It is acting like it has an inverter board problem since it has sound, changes channels but no picture. I saw one 25v 470uf capacitor on the power board that has slight leakage and slight bulge. Power is getting to the inverter board. Could the capacitor be the problem? 

Luis Gomez: Thks was very helpful

If you wake up the next day and the tv's been off for 8-12 hours then you will get a response initially then it will just disappear in "brain dead" mode. the thing is, my capacitors are not bulging, even slightly so this has thrown me off. Can you help? any suggestions? Kind regards

Zionist JewTube: I won a 42" CLASS LED LCD TV/ TV ACL DEL When I set it up and plugged the cable wire / the power cord, everything was working fine. I could watch the TV no problem. I watched it for about 5 mins. then turned it off. I turned it back on at night, & no picture, only sound. All the channels are working fine, but I can't even see the menu or any options on the screen. It's Black. Will this video show me how to fix the type of TV I have as well, or it's just for the type of TV you have?

cantab3: Hi, Tampatec: The LG 32LC2DB is connected to the Humax Freeview box HDR-FOX T2 & has been working beautifully for months. Recently, 30 min into the programme, the picture went off and 'No Signal' was displayed on the screen. The Humax was still receiving the programme from the antenna, as seen in the digital readout on the Humax. Five minutes later, the LG tv made loud noises through the speakers, like popping and electrical noises. I pulled the power cord out. The next evening, a similar event occurred. I notice there are many screws to un-do to check what is happening inside the back of the TV. Any tips as to what may be malfunctioning and where the 'bulging capacitor' might be? Many thanks.

Job Seeker: Subscribed !!! Cool video

Ross radman: Thanks man, fixed mine a treat, the same 4 cap's - cheers

Nguyen Bo: Thank you so good, it is a time I try to do my own

evelyn bibbie: I have an Lg 40in model number 42LD520 . Only half of the tv picture appears. Which is on the left side. On the right side it blinks first purple then grey, then a strip of white with black lines down it. That part doesn't blink. Could you please offer me some help to what could be the problem and how to fix this. Thank you for any help you can offer.

Petra Rimsky: Just found your tutorial.Thanks, now I dare attempt the repair.

Chris Richardson: Hi, novice here. DC or AC capacitors for this fix? Thanks.

James Colledge: Hi. I have LG 37" LCD. ( Do not have the model number to hand at the minute. ) At times the telly is working fine and then other times it just doesn't seem to pick up channels. All other lights are on on the screen. Does this sound like a problem on the main board ? Thanks in advance 

Frank Pitochelli: check out Norcal 715.....there's a real tech. he is very good and shows troubleshooting tech. to component level...Grants pass also.

Eric Agront: thanks my tv she works now thank you so much man.

Chase Lohmeyer: Did you break my ass? I almost broke my ass.

Dreanadine81: HI, I have a lg 50ln5400 tv that upon being turned on it goes to a black screen and I am unable to do anything with it. Do you know what could be the problem and how I can fix it.

Eric Rodriguez: great vid just saved me some cash for a simple repair...thanks 

Frank Pitochelli: how about some solder wick, and a real solder iron. I'd like you to come to my shop and troubleshoot an actual DOGtv....meaning not an easy cap fix, but an actual circuit repair, when you can trblshoot and repair a real technical problem then your doing something. sorry for the critical input but, when you have been in this buss. for 36 yrs, it maddening to see a table top repair and no technical ability for actual circuit troubleshooting....and you cause ppl to think all repairs are a snapp when the majority of repairs are very difficult. Hey, it's just a comment !

Travvis Stayton: I have an older (6 or 7 yrs) LG LCD 47 inch that had perfect color screen for about five to ten minutes then would act as if the contrast was turned way up. It would do this after everytime I turned the tv off and on again (waiting five or so minutes) It didn't matter if I went in the menu and changed anything, it would remain the same. I took the tv out of commission and started researching. I found that most of the time the tcon board was the culprit. I took the back of the tv to locate the board, took the board out to see off there was anything physically wrong and put it back in. Now, after putting it all back together, I turn the tv on there is no picture/sound and no menu or anything else. It does power on though. suggestions?

James Colledge: Watching a lot of your stuff recently dude so cheers. I'm just trying to find the best place in the UK to buy capasitors, ic chips and such right now if anyone can recommend anywhere ? 

Mark Michael: I have an LG Flat screen tv when I turn it on it switch off by it self in like 1 sec. i took the batteries off the remote that did not help. i visually inspect the capacitor they seem fix. No noticeable bad cap. what might be the problem? thanks 

justin extine: hello i have a LG lc7d the tv screen would flash on and off and you can hear popping sounds from the speakers and it will continue to flash untill it turns off .... i replaced the bad caps on the power board if i leave the tv off over night it will play fine for a few hours sometimes most of the day but after a while it will go back to doing the same thing 

Tito Rodriguez: I have a 42 LG30. It has the white screen. Audio works. What would you recommend I check? 

Sadochrist: I just picked up a flat screen that someone had left outside by a tree. I got it home and could see why they got rid of it, blank screen. Sweet I just got a free flat screen now once I repair it. Thanks man really informative.

AirBurn1: Do you know if the 32LC7D has a FFC behind the front bezel?
