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?

adz260689: Hi Tampatec!
Well, Sadly I have one LG unit thats doing the same thing, its a UK model (
I guess that doesn't make much difference) It does exactly that....nothing.
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?

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.

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

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

troubleshooting tech. to component level...Grants pass also.

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.
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

justin extine: hello i have a LG lc7d the tv screen would flash on and off and you can

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
