Re: LCD Screen problems
I did a couple of google searches. I found one company that listed flat rate repairs for LCD at $350 for a 32" TV. This is exactly my replacement cost for the 'cheap' TV that it is. Actually, I've seen a toshiba on newegg for that, which is probably better than my shitty emprex from Frys.
Everything I've seen so far, seems to say that these repairs are beyond a DIY.
It looks like economically, I should just buy a new one. I couldn't find anywhere that actually sold LCD panels. Would I have to buy that for my specific...

Re: LCD Screen problems
Bummer, replaced the T-Con board, and TV has exact same problem.
The only other component between T-Con and LCD screen is Hitachi Inverter board. I'm guessing this is where the 'bad line drivers' would be located?
I can buy a replacement inverter board for $40, but I just dumped $40 on the T-Con board, and I'm just guessing here.
At this point, I'm tempted to just replace the whole thing.
Anybody have an opinion on this one?
Thanks, MikeLeave a comment:

Re: LCD Screen problems
Finally got back to the TV. I was able to find an exact match for the TCon on ebay for $40 so I ordered it and hoping it fixes my problem.
However, I noticed on the signal processing board, there are 2 bulging caps.
One is labeled Misuda 1000uf 16v. I can't find anything about this cap.
I'm assuming I can replace it with any relatively low ESR cap? I have a bunch of extra's from a previous order for a motherboard.

Re: LCD Screen problems
If I open it up, is there are way I can measure something to tell which is wrong.. I only have a DMM.
Assuming I can order these parts myself? It was a cheap TV a few years back, so I don't know if I'll be able to get parts or not.
Thanks, Mike
P.S. I've had 4 major electronics go bad in 2 weeks... spooky.Leave a comment:

LCD Screen problems
I have an emprex LCD tv that is having problems. Started with just a couple of vertical lines going out, then intermittent whole bars would go in and out, now the whole half of the screen is a weird pattern.
Any idea's what this might be? I haven't opened it up yet, but searching to web, I'm confused whether it might just be bad caps, or inverter board or CCFL's...
Any suggestions welcome.. I'll be opening it up tonight.
Thanks! Mike -
Re: Dell E310 problems - Need advice
Thanks, I understood what you meant... good info.
In reading my post, I think I was not being clear
The only thing hooked up to the computer was a keyboard and the system was still having
[I]USB controller[/I] problems.. not the other 'hardware'.
I have to look at the motherboard and see what all caps are on it.
I've seen people on here recommend from replace all, replace above 480 and replace above 860... and oh.. look out for those 220s.
I'll probably...Leave a comment:

O.k. Found this thread with a similar problem... Looks like I need to recap and retest..

Re: Dell E310 problems - Need advice
Well, Vista seemed fine, but I tried to boot into FreeNAS, a BSD based OS, and it immediately gives an I/O error on the USB-Hub and shuts it down. Only a keyboard hooked up.
Definitely something still wrong within the USB hardware for the machine.
Suggestions on anything I can check with a DMM or should I just order those two low ESR caps first?
Thanks for all the help so far, Mike...Leave a comment:

Re: Dell E310 problems - Need advice
I would assume that Apples Ipod is within spec (hopefully).
I'm just wondering if there could still bad caps on the board (or my changed caps) and that it just appears stable right now because there aren't really much USB load on it right now.
I guess to know, I should get one of the ESR devices... That MicroESR looks good, but the website looks questionable.. Maybe I'll just get the Blue ESR instead. It would pay for itself with just one saved motherboard...

Re: Dell E310 problems - Need advice
Update: Finally got the machine back, less all the USB stuff hanging off and the original HD.
Opened up the PS, everything looks fine.
I hooked up a new USB kb and mouse and new SATA HD with Vista instead of XP.
Machine still has hi ESR Panasonic FM caps from earlier.
Boots fine and running Prime95 for over half-hour so far..
Previously, XP would not boot at all, even into safe-mode.
Could this still have been a bad driver or related to one of the USB devices pulling too...Leave a comment:

This is the HN in 10mmx12.5mm. Would that one work? It's 200 lower than the original on ripple current. No problems though, since HZ is in stock, just trying to understand for future reference.
I'm getting the machine back tomorrow, so I'll checkout the PS and see what I can find out.
I was using the 'ESR' column in the filter on mouser to search for Impedance. Guess that wasn't right.
Thanks for finding thos...Leave a comment:

Re: Dell E310 problems - Need advice
I checked mouser, couldn't find anything with that low ESR.
On digi-key, the only thing I found was
[URL=http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-3094-1-ND]Nichicon CAP POLY ALUM 1000UF 10V SMD r PCG1A102MCL1GS[/URL] at a whopping $2.75 each, but I don't know if that is the right kind anyway.. SMD?
Looks like badcaps store is my next stop.
Also, is there a chance that those are still my problem caps? Or are they just more likely to blow sooner?

Re: Dell E310 problems - Need advice
Hmm.. those are supposed to be good caps.. Maybe PS caused this?
Looks like both my ESR and Ripple current are way low with the FC caps.
I'll have to search around on Mouser for something to meet those specs. I work only a few miles from their warehouse, but they don't allow pickup. Oh well, last order only cost $4.50 and showed up 10am next morning.
I'll have to wait to see what other caps need to be replaced before ordering.

Re: Dell E310 problems - Need advice
Thanks for the detailed instructions.
It was the two big caps between the DDR slots. They even have the same blue line (marker?) across the top. I think this is an original from Dell, i.e. one owner. There is a symbol of some sort before the KZJ letters.. Almost an outline of a rectangle, but looking close, it looks like there are slight flares on the outside top corners and right in the middle of the top as well. Sort of like outline of a dutch oven? Kinda.. maybe..
When I get it back.. I'll check the other...Leave a comment:

Re: Dell E310 problems - Need advice
I was able to get them out ok with the 40watt pencil. When I tried to get the left over solder out by using the braid, I put the braid on the board and tried to heat through it.. I think this heated up the whole braid and caused the heat discoloration to the sides.. Guess I should heat it up, then push the tip of the braid onto it? Never used braid before.. thinking of getting the pneumatic thing instead.
Since the behavior of the board has not change, I'm hoping I didn't damage the trace. Can I check the continuity...Leave a comment:

Dell E310 problems - Need advice
First off, great site. Within 1 week, my LCD died, SageTV HD extender died, and my friends Dell E310 won't boot into xp.
Fixed my SageTV and LCD no problem, but the Dell is still having problems.
Symptoms started with machine not shutting down, then problems with USB syncing to Ipod. Now, it won't boot into windows, BSOD. However, it DOES pass all the Dell diagnostics!
Inside, the two 1000uF 10v, KZJ (M)105, 5(2), DI between the RAM sticks were leaking brown stuff on top so I changed those, but made no difference.
There were several 470uF caps sitting...
