...bad regulator (ic's, transistor, diode). 4- alway's look for cold solder joints, it's a small posibility, but it may be your cause for bad regulation or changes in power goin in or out of the ...

bad. These IC's operate at a very high temp, and usually only last 4-5 years. If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see

...bad video IC, so B4 you buy a D board you need to check the CRT board if it has one IC on it measure ohms across the B+ capacitors on the CRT board, if shorted the IC is shorted and also the supply ...

...on a Hantarex 19'' monitor with a eygo 1820-h19 chassis Bad grounds on the vertical IC. Or it can be a bad IC. And always check your electrolytic caps that are in the immediate area ot this

...blue convergence manually or by using factory preset...the unit is 7 years old, is my picture tube bad? You have bad convergence ICs. There are 2 ICs in the convergence circuit, one is for the Blue ...

...in the immediate area of this IC, bad caps will heat up the vertical IC, and cause bad grounds. Replace the caps and Vertical IC as needed. Should be a standard fix in this case. Thanks for

...IC. A bad capacitor will run this IC quite warm and will produce bad grounds. If you inspect closely, you will see solder rings [cracked] around each pin of this Vertical IC. This would be the first ...

...of the vertical IC. Replace the three or four capacitors next to the IC. A bad capacitor will overheat an IC and cause solder grounds to separate. Thanks for asking and show a few hands of

CAN'T ADJUST COLOR Either bad color crystal (need an oscilloscope) 4.5mhz. Check for 5v on pin one of e-prom ic,  If low, bad e-prom ic,  If 5v its good, bad y-c deflection ic

5AM3 Either bad solder connections on the vertical output IC or bad part in that circuit, IC or something else. I presume it is NOT a flat panel set but has a picture tube as no model number is listed
