So, ive done some searching. I really want to hear some peoples $0.02 on this. What have you done/seen/repaired etc. I have 3 of these on a shelf that i want to repair soon.
for instance, i had a tube with a shrunk image, looked like a 19" image on a 25" tube. I replaced the diode at D135 (if memory serves...)
Ill contribute what I stumbled upon from ken layton (thanks ken)
HANTAREX "POLO" MONITOR REPAIR GUIDE 1
GENERAL INFORMATION
Made in several CRT sizes from 10" to 33" with the 20" and 25" being most commonly encountered versions. Comes in "universal" mounting frame. This monitor has a switching regulator power supply under the vented metal cover.
CRT INFORMATION
The 25" version uses an RCA # A63ADT10X05 picture tube. Use B & K rejuvenator socket adapter # CR-23 to test or rejuvenate this picture tube.
YOKE INFORMATION
The Yellow & Orange wires are the horizontal deflection section and the DC resistance of it is 1.7 ohms. The Red & Brown wires are the vertical deflection section and the DC resistance of it is 5.4 ohms.
FLYBACK INFORMATION
Original Hantarex part # 28820061. The H.R. Diemen replacement is # HR7215. The MCM Electronics (www.mcminone.com) replacement is # 142-210. Happ Controls replacement is # 49-3097-00.
CAPKIT INFORMATION
These capacitors go on the neckboard:
C12 100 uf @ 25 volts, C14 4.7 uf @ 250 volts, C18 47 uf @ 25 volts, C21 10 uf @ 50 volts
These capacitors go on the main board from the center to the right side:
C130 100 uf @ 25 volts, C137 220 uf @ 35 volts, C139 1000 uf @ 35 volts, C142 47 uf @ 25 volts, C144 1000 uf @ 35 volts, C146 4.7 uf @ 100 volts, C157 220 uf @ 16 volts, C159 2.2 uf @ 50 or 100 volts, C160 2.2 uf @ 50 or 100 volts, C165 1 uf @ 100 volts, C166 100 uf @ 25 volts, C168 100 uf @ 200 volts, C177 47 uf @ 250 volts, C181 4.7 uf @ 250 volts, C182 22 uf @ 50 volts, C184 10 uf @ 50 volts
These capacitors go in the power supply section (left side) of main board and you must remove the metal cage to access all these capacitors:
C111 220 uf @ 25 volts, C112 22 uf @ 50 volts, C114 22 uf @ 50 volts, C121 100 uf @ 200 volts, C123 10 uf @ 100 volts, C125 470 uf @ 35 volts, C129 220 uf @ 25 volts
This capacitor goes on the remote adjustment board:
C401 1 uf @ 100 volts
Zanen Electronics capkit # 810 is the correct kit for this monitor. Bob Roberts (www.therealbobroberts.net) also stocks a capkit for this monitor. Happ Controls # 49-5083-00.
