Good day, husker_shoe;
Good question, I will try to help anyway. The boards are on the left side TV looking from the back. It has a shield around it, remove. The caps are big and black, they look the replacements(only ones on board). Here's what says about this issue:

If the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). (LED does not stop blinking after plug in) On the DM
Good Luck, big IRISH. ps hope this helpful!
PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 uFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 uFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).
It is not an easy job, it will take some time but since you have it apart there is another problem that will accure so might as well do this too:
Tile or block pattern with no video or OSD. Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002).
All the parts have location numbers like C8F29 that will tell you what and where these parts are.
Good luk, big IRISH.

Logik l22 fed12 stuck in wont come out of standby

sounds like a Power Supply Board gone bad, or an internal fuse could be the problem, (which is an easy easy fix. ) just make sure the unit is UNPLUGGED from the wall socket. If it is a power supply they too are easy to replace also.. be sure and be careful some of those cap. can still store energy and give u quite a jolt. NOTE ,,, take pictures of the inside of the TV,. take close up of the power supply and make sure u get the model # off the power supply board itself. and get an exact match when u order. I usually try Shop first. DO NOT remove the power supply till u have the new one in your hands. that way u won't for get how it hooked up..

My samsung flat screen makes loud noise and wont turn on

sounds like a power supply board problem. Be careful. I would up plug it from the wall socket.. the sound u hear MIGHT be something on the circuit board heating up and about to POP. The power supply boards are not hard to replace. just make sure it is unplugged and be careful they can carry a charge even unplugged. Caps etc can Zap u.. as I tell every one , take picture of the insides of TV and the power supply board and a close up of all the numbers that is on the power supply. order the exact same part.. do not remove the bad board till u have the new one ready to go in.. good idea is use a grounding strap. the only cost a couple dollars or so.

My board is IBM rev. 2.8 pn 19r2563,i just clear the cmos,after that the board didn't boot anymore,no power at all,,please somebody help what exactly the problem is..

Look on the board for bloated or leaking capacitors- these are caps that have an x on the top and a yellow or brown substance out of them. If the are fat they are bloated. Next, I have had this with bad power supplies. Try another power supply or put that one on a power supply tester if you have one. It will tell you if all the voltages are there. It only takes one voltage missing to give you major headaches. If the unit is old try measuring the CMOS battery. A dead one will not let the computer boot but that is after power will come on.
If you have a bad capacitor on the board it will be needing replacement- I fix them but not everybody goes to that trouble.

Bad power supply/capacitors Xerox M15i WorkCentre. how do I order parts, and how do I repair/replace

I have to make some assumptions here. Since you know that there are bad capacitors on the power supply board then you'll need to get replacements. When you go to order these make sure you order the exact part i.e. .5ufd, 100vDC, 70temp and 57hz frequency. This is a poor example but ordering the exact replacement part is very important. There are hundreds of places to get the caps online. Now to replacing these. If you have enough electronics knowledge to determine if these caps are bad then I have to assume you can replace these fairly easily. This will only require simple tools i.e. anti-static 30w watt soldering iron, anti-static desolder device, anti-static wrist strap with known good ground. Appropriate solder. Good luck

I hooked up the spark plug wires wrong on the distrator cap it is a 1988 4.3L 6cyl how can i find a diagram to fix this problem or tell me hoe to fix it

find the firing order which is usually on the intake manifold,put the crankshaft on 0 degrees top dead center,pull off the distributor cap and mark where the rotor button is pointing,start #1 cylinder at that spot(which that spot should be pointing towards the rear of the distributor),and # 1 cylinder is front of engine on the drivers side then it goes next 1 back #3 then # 5,and the passengers side front is #2, then #4,then #6 towards the back,and the firing order goes clockwise on the distributor.if it spits and sputters or back fires,then the timing firing order is off 180 degrees,so move every wire to the exact opposite on the cap,so your #1 plug wire will be opposite from where you put it first.then double check the firing order and all plug wires then try it.the firing order is:165432,i still dont know how to send pictures.

Power supply most likely... It's a common problem with this particular model and we've seen quite a number of them for exactly what you're describing.
You need to replace 19 caps in the power supply 4) 3300uf/35v, 8) 2200uf/25v, 6) 1000uf/10v, 1) 1000uf/16v and you can go a little higher in the voltage of each cap for greater reliability.
It's best to have an ESR meter also and test the remaining caps as well.

I'd assume this machine uses an ATX design power supply. ATX and other late designs (after the days of the AT style units) have a standby voltage supply which powers just a small portion of the motherboard circuitry (voltage= +5 volts). Your problem is likely caused by one or more electrolytics in this standby section. If you open the supply, you should see at least 2 switching transformers, likely sitting close to each other. One will be large (for the main/full power) and a small one (for the standby section). Usually the bad capacitor is on the primary side (on the side where the switching transistor is). It may be a 10MFD/50Volt or 47MFD/25Volt, or some value close. If the bad cap is on the secondary side (the section which is connected to your motherboard), then the value will be something like a 1000MFD/10Volt or 16Volt, or 1500MFD, 2200MFD. This capacitor will be physically larger than the one noted for the primary side. I can't tell you the exact location on the board where these capacitors might be, except they will be close to the small transformer mentioned above. If you have a digital camera, and could take a pic or 2, I might be able to point to the exact suspect part. You could send pic to Of course, you need a solder iron/solder, and a little skill...
