wells U5000-25K5108

[worm]

  Hello all it's be awhile since I been in the room for info, Ineed help please.
I have a ws 25k5108 that makes a ticking sound like it's in shutdown or the hot is bad.

 The checks out good so I unsoder the right side of L102 and conected a 75watt bulb and the side to ground and applyed power andthe bulb lit so the power supply is good so.

 where do I go from there what else should I check or be looking for?

Have you actually metered the B+ voltage from the monitor psu circuit?

Bt all over the place even when I take it from L102

Does it work at all?

Sounds like it still has a power supply issue then.
That should be quite steady and constant.
There should be actual test points for the B+.
And a potentiometer to adjust it. (which could also be bad)

My first U5000 was a nightmare.
But it would literally try to burn itself up. 
There were several "revisions" so documentation may be a little off here and there.

Wells-Gardner issued three different "service kits" (retrofit kits) to fix all the problems these monitors had.

Power supply kit

Vertical output kit

Horizontal output kit

It's strongly advised to buy and install all three kits since even if you don't have problems with one section, these kits will prevent problems later.

Of course I'm assuming you've already done a capkit on this monitor first, right?

Do you have to get the retrofit kits from wells arecan I get them anywhere?

Can you tell me what the parts are in this kit?

You have to buy the kits from Wells-Gardner's part department (1-800-336-6630 or 708-290-2100):

# S04E0000-000F Service Kit, U2000/U5000 Power Supply retrofit

# S05F0000-000F Service Kit, U2000/U5000 Vertical Sweep retrofit

# S01J0000-000F Service Kit, U5000 Horizontal Output retrofit

# S-KIT CAP U50 Capacitor kit, U5000 (if you haven't kitted yours then get this too)
