Question about Televison & Video
I have a 51m200 hitachi tv and have no video, no audio. I have on screen display and can switch from one input to another, magic focus works fine as do all of the customer controls, but no matter what input I go into I have no pix, and no audio
it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

You need to replace both IC they are both STK392-110 they are located on the large heat sink on the far right side of your Tvs' chassis Heres the link for replacement ICs

Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

Error 4 is listed as an overflow in the convergence section.
1. Check the placement of the sensor
2. perform an Adjustment check of th H/V size & centering
3. Conv. amp. gain check, check these resistors:
R041, part # 0790024R, RES.CHIP 1/16W 100 OHM
R046, part # AQ00164R, RES.CHIP 1/16W 75 OHM TAPE
R050, part # 0790059R, RES.CHIP 1/16W 47K OHM
R058, part # 0790054R, RES.CHIP 1/16W 18K OHM
R062, part # 0790047R, RES.CHIP 1/16W 5.6K OHM
