Re: Olevia 242TFHD-T11 42" TV Start Up Problem

I have the same model TV and am experiencing a similar problem. Glad I saw this thread: THANK YOU tom66 for the advice on cap ordering as I was *just about* to place an order for that Amazon kit. I will start a new thread this afternoon so I can post pictures of the power board. I would like to confirm my suspicions that my only problem is bad caps.

See y'all soon!

Hi all, Just replaced the power supply in my set and it works great thanks to this thread. You guys are awesome, and saved me the price of a new TV vs 50 bucks for the power supply.
Thank you all!!!

How difficult is it to get the back cover off of this set? Can it become while standing up or must it be laying down? Thanks. I want to work on mine, but due to a spine issue it would be much easier if I could do it with it on the stand. Thanks.

I'm fairly certian you will be able to remove the back cover off with the plasma upright, but it would most likely be easier with it lying flat. I'm not familiar with this model but the handful ive come across have just been a decent amount of screws to remove.

Can even hang the stand off the edge of the table if you dont want to remove it, while it is lying flat.

I'm fairly certian that you can work on it upright (can help if you want to be able to glance over and see if there is any life on the screen, in my case recently)

But for removing boards, etc - lying flat is signficantly easier.

I laid mine on a towel face down on the dinning room table with my wifes help and a bad back as well. I wouldn't recommend trying it up right.

You've got to remember I had just also replaced the mother board just a week before the new ps and it wasn't just the caps, it was a completely factory fresh new ps.

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

I remain skeptical. Bad caps can cause stuff like greyscale video (dropping analog supply), digtal glitches (freezing picture, lines, etc.) Maybe brightness if 24V was low. But improvement of colours?

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

It really did. Picture was blocking before until it warmed up and the colors were no way near as bright.

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

How do better caps improve picture quality and colour??

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

That's the one on ebay that I also purchased. There was one wire on the new ps harnese that was placed in the wrong pin hole slot on the invertor plug next to the ps. Just match all your wires for the new ps. Mine works great. Color and detail have greatly improved as well. I think my Olevia is a top notch tv and didn't want to give up on it. The back is easy to remove and the ps is simple to change. No soldering required.

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

Avoid, a rip off and problematic. Simply make a note of each of the caps you have on the board and order Panasonic FC, FM or FR from DigiKey. Total cost, including shipping, will be less than $10 and you can be guaranteed they'll work perfectly. Manufacturers often change boards mid version because of supply or price reasons, so the caps in that kit could be incorrect. Also, no mention of quality - cheap generic caps will die in short order.

Got em thanks.

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

They are lock/latch style connecters you can pull them off, might have to wiggle. If you still can't get them off, use a small flat head screwdriver and wedge between the latches and then pull again. Also would be easier if you had the screws in on the board.

How do I remove these clips? I don't wanna yank em and mess it up...

Alright. Thanks for the help! I will be able to work on it some tomorrow!

Everything mad professor said is right on.

If you have the whole tv completely on top of a flat table with a towel / or blanket inbetween so you dont scratch the plastic around the screen, then you wont have any issues from leaving it down for a month.

Youll want to buy low esr caps, and replacing them all should fix your issue. Every brand makes many types of caps, so make sure you are looking at specific series that are recommended on this site.

Generally panasonic FM series is a great choice for these. From the pictures you can see some 1000uf 25v caps, some 470uf, and so on. When searching for caps you want to first choose aluminum caps > radial caps> the voltage (25-35v) > the capacitance (470uf, 1000uf, so on) > the lead spacing > choose the right low esr series / brand you want, and make sure its not to large to fix within the tv (not usually an issue on these huge olevia tv's) . You can always increase the voltage on caps, so if they used a 25v you can use a 35v cap, since thats the max voltage before it will live a shorter life.

Digikey is a little more exsp then mouser, but has a cheaper shipping option. They list a little less data on mouser (no lead spacing) so its harder for begginers to order from. They ship in 1 day to texas and neighboring states, but your between both companies so should get it fast either way.

Re: Olevia 242TFHD-T11 42" TV Start Up Problem

Thanks much for the help! How do I find the values of them? Are they the numbers on the side? I took a couple pics if that helps identify them. Also, what stores would carry these or should I just order them online and wait? I have the tv laid down flat, some people are saying thats ok, others say it is going to ruin it....

Laying down the tv is fine, as long no direct pressure is applied the the LCD itself or if it hanging off a edge of a table that could cause the set to bend.

As for stores and onliner retailers,

Forget radioshack, unless you have a component retailer in your area I would just order online.

There's DigiKey and Mouser

http://www.digikey.com/

http://www.mouser.com/


I recommend digikey. They pretty much have everything, they have a simple layout and offer links to datasheets and design diagrams and the only one I know that offer First Class Mail which is usually about $2.45 to ship to Orlando, not too mention it cheaper then Priority and other carriers. They ship from Thief River Falls, Minnesota.

As for identification of caps, a good example of listing is
Brand, Series, Capacitance, Voltage, Diameter, Height, Lead spacing.
You can use a caliper to measure the diameter and height and lead spacing.

For example

Capxon KF 1000uf 25v 13x25mm 5mm

Usually the series is located near the temperature rating.

HTH look forward to assisting you.
