watcher's activities list on eevblog:
- watch a guy scrapping the basement for old electronics
- watch the same guy walking at electronics fairs and ... do nothing
- see non sense - "repair" videos (i can't remember of any video of him actually repairing anything)
- see fotographs from postcards packed together with adaptor boards.
- see how you mount a camera on a bench
- learn to solder ?
not to mention, the hidden advertisements, emotional catches from showing his child (using the child for this purpose dave is inqualificable) ... you add to the list.
best to all.
peace.
no-one is asking you to watch Dave's videos - if you see something on TV you don't like - you change to different channel. so please do the very same in this very case as well
I like Dave's videos - i'm watching Dave's channel instead of TV Dave is a great guy not afraid of being honest and share his opinion in the public !
and regarding the postcards and unsuccessful repair videos - we all like those ! either you pick up some information, or you learn something or just watching them for entertainment. i rather watch Dave's mailbag than an episode of some stupid TV series...
if you don't like it, then go and watch something else ! it's so simple ! -
You can't handle criticism too well.
Ofcourse I follow different blogs and information sources. There is also a subtle difference between "don't like" and logicaly present some arguments.
You seem to agree that a video called "repair video" consisting of CAP checkings to be enjoyed because is fun. Which is exacly my point. Well.. that's logic too.. sleep tight.
p.s from the registration terms and conditions we see:
"5) This is an electronics forum, so try to stay on-topic."
so ... yes.. dave is way off topic with these pseudo repair videos, but we need to stick on topic. see how many ideas of repairs popped up from users commenting to the video, not from the initator of disccusion. i'm don't know about you but I like to think. so let's count. he checked caps, you suggested checking logical buses, he checked power regulators, you indicated probing with a scope to detect a difference when glices occured. see my point ?
i'm not sure about "my mom tv story" either. it sounds to me like a pretext, because it made me think at the following dialog:
day1:
- son?
- yes mom !
- come here!
- just a second. i have to post something..
- bloody blog.. when he will take a real job...?
- ok.. what is it ?
- my tv just died.
- ummmm
- can you repair it ?
- sure mom.. why not.. i will film it.. and post it so everybody sees it..
day2:
- well ?
- no mom. it is beyond economic repair (?)
- really ? so i need to buy another ?
- yeap..
that was fun.. not the video..

yes. these are a bit better, but still not good enough. these are really really basic things. ofcourse, for a beginner, probably that's OK (with the note: begginers should probably first read some books, then be entertained), but yes.. ok for beginners.
from a random pick.. compare with this:
-
stick with the "idiot" version.
meanwhile explain two things:
- "care" and "careless" in a blog context. and
- what are the things you disagree / agree

WTH? I thought Dave said he would post the other video with the final fix? Its been a long time now.
Are we going to have to wait until the fall premiere of the next season of eevblog until we see the conclusion of this cliffhanger?
WILL DAVE FIX THE TV IN TIME OR WILL IT EXPLODE?
WILL DAVE GET 240V THROUGH THE WATCH AND BE FLOWN ACROSS THE ROOM ON CAMERA?
WILL DAVE CUT THE BLUE OR THE RED WIRE?
WILL DAVE SAVE HIS MARRIAGE AND HAVE A GRATEFUL MOTHER IN LAW?
STAY TUNED
SAME TIME
SAME CHANNEL -
Man... There sure seems to be a number of whiners about Dave's videos on Dave's forum.
It's easy to be so critical when you don't know how much work goes into making videos and running a forum. Most of the time it's a thankless job.
So he didn't fix the TV in one video, big deal. He spent a number of videos on a piece of test equipment (forgot what it was) and never fixed it. Then in other videos the solution is as simple as an AC line filter. People will bitch either way. If you learn from Dave's line of thinking and troubleshooting methods, that's more important than if he actually fixed the TV. -
A while ago I got really fascinated by faultfinding and repairing, I know seems to be a black art, however at 60 years old, I have found a TV repair shop thats more than willing to help me along, and I'm loving it so much, the young guys in there seem genuinely pleased to help an old git,I have learned some of the boards and what they do.now I have forgotten something though, is it the inverter boards,Y main,Y sustain,X main , buffer board or T Con that run flat out, I think it's the inverter board,and is it, if the inverter board goes high damage will occur to the other boards, I maybe totally wrong which means later when I go down to the shop,Ill have to go through the whole excercise again.

No kidding. The thing I like is that level of transparency with Dave is very high. He shows what didn't work. He shows it isn't all necessarily fixable, or worth fixing.
The real-life nitty gritty involves failure, and being willing to have your failures in public for everyone to learn from is a public service.
Real life isn't like TV and movies where engineers figure out the problem by the end of the show... -

Hi,
There was no sign of an inverter board on that TV, so i'd assume it is a LED back-light.
There was the common 25v supply used by inverter boards, unless the board was hidden under the white plastic base.
-
The ccfl inverter is embedded into the main power supply (big transformer with yellow tape around it). There are two cables going from there to the right and left side of the tft panel.

See those thicker than normal cables and special type of connector with far apart spaced pins. Those look like ccfl backlight to me. But I don't think it's the backlight since it was on most of the time. LED backlight doesn't need that type of cable or connector. Like others said already looks like digital board problem. -
Has anyone been able to view Part 2? There's a link in the description to this:

Bango ... it's up. Thanks Dave!

I have fixed a few LCD monitors, bad caps, bad resistors, these are easy problems that I could fix.
Then I came across 2 monitors (manufactured year 2009) that have the 2 seconds backlights turning off, I couldn't fix them and told friends that the electronic boards were good, all good caps so I think is the ccfl, however I don't have any spare lamps to test with to find out for sure. I just gave up because you have to factor in personal time for such small gain (LCD monitors are cheap now).
I can't wait to see what Dave's problem is. My guess is loose connectors?
I can't believe there are idiots here registering just to whine, please make your own video and see if you can do better. I am pretty sure Dave shared his videos for people who want to watch them. Also I don't understand why he should take any criticism from his own forum?
Personally, I prefer to watch Dave's videos over others because they are entertaining, realistic and he does not try to show off. People if you don't like it don't watch it, it is simple really go watch other videos. -

Certain older Samsung and many modern Panasonic plasma TVs will damage Y-buffer boards (SU/SD or SM) when the Y-sustain (SC board) fails. -
Well, I am an idiot who registered here just to say that I really enjoy Dave's videos. With this one, he could have waited until he'd fixed it and edited it down to look like he went straight to the problem with no hesitation. And I'm sure someone with a lot of TV repair experience would have gone to it straight away. But we all know the feeling of taking the back off something we don't have a lot of experience with. That's what this video shows, and people are having a lot of fun speculating and saying what they would try next.
If you think that boring, badly-shot lecture on PLLs is better, you're welcome to it. Give Dave a fair go! He's Australian, not Austrian! -
Nice fix Dave, I have fixed quite a few with that same connector. Same issue, I think it is related to the connector being flexed during manufacture perhaps.
A Toshiba 32" LED Smart TV, and a 26" cheapie. -
Hi,
Not meaning to be a kill-joy, but was it a good idea to completely cover that board with tape, any possibility you may have further problems with temperature build up from the now enclosed ic

benQ/dell/acer?
look for c5707 transistors in the inverter, those die producing effect you describe -

Thanks will try looking at those transistors.

25" Hannspree HSG1064 (I'm surprised all caps are Nichicon)
19" HP (Rubycon caps)
Just realised I can try taking out the 19" ccfl from the HP to test on the 25" one. -
What are you offering on your channel? Do you have one?
nothing really and no, i dont have a channel and that's because i'm not the one selling concepts around.
if we were to compare something, let's compare similar blogs across the spectrum.
your pick.. let's start with 3 proposals and rank them on (negociable) criterias:
- electronic insight offered
- degree of time "loosing"
- actuality and news
- [add more]
don't know which other criteria fits in, but eevblog fails the most and wins the "nerd entertainment" section.
any other criteria you might find usefull. please add. excuse my english. i'm not a native speaker.
Shit, I think EEVblog should give Dave the boot and get new host for the show. Maybe someone who knows more about eletronics?

My only complaint is that if Dave was going to do a TV repair video for blog #630, he should have done the famous RCA 630 chassis, which was the first mass-produced TV set, introduced just after WW2:
http://www.tvhistory.tv/1946%20RCA%20630TS%20TV.htm
Like the IBM PC in later years, dozens of manufacturers copied this design more or less completely for the first few years of TV. 630-derived sets are still widely available and popular among the vintage TV crowd.

my 2 cents..
there are lot of numbers related to iconic stuff, but you simply can't make all the videos according to those numbers... the EEvblog #555 made sense - everyone knows the 555 timer or at least heard about it but for example the 630 chassis - it's definitely a milestone - but only a few know about it (for example i was not aware until i red you post).
