KV32XBR45

Convergence | Unit has mis-convergence of red and blue vertical lines. they are displace horizontally. tech replaced the crt without correcting the symptom. | R789 open h-state not operational. what No finding is a resistor that appears to be open on this ""c"" board it is r789 the value cannot be read nor is it listed in the esi software parts list. trying another value from 10 to 20 megΩ. this resistor is in the ground return of the h-stat resistor that is installed in the crt. tech needs to try different values to try and make this set converge horizontally. this tv converged with a 10 megΩ resistor.

Convergence | Kv32xbr45 unit has sever horizontal static convergence error. tv cae to us from another shop wsound the crt and flyback was replaced. customer call us for secont opinion. | Suggest tech look for r789 and see if it is open it is on the on ""c"" board. it the value is around 10 meg. tsound are two different chassis and crts used for this model. if they have the older chassis type that requires h stat convergence (crt board has h stat control) i have attached the two service manual supplements, and the sb325r1. however none of them have show this resistor. we were able to install a resistor in this unit that was a two 10 megs in series. trimming the value by adding another 10 meg in parallel with one of the other 10 megs. we were able to converge the set. original part was not available.

Convergence | Kv32xbr45 unit has convergence of all vertical lines are displace horizontally. tech replaced the crt without authorization. this did not solve the symptom | Suggest tech look for r789 and see if it is open it is on the on ""c"" board. it the value is around 10 meg. tsound are two different chassis and crts used for this model. if they have the older chassis type that requires h stat convergence (crt board has h stat control) they need to order the older crt as per the manual. if newer type (no h stat) then the new crt as per service manual supplement -1 is needed. crt 8-733-743-05 the h stat is done using the yoke ring magnets. i have attached the two service manual supplements, and the sb325r1.

Convergence | Kv32xbr45 convergence is way off in the horizontal direction | Unit has an open r789 a 18 meg 1/2 watt resistor for the horizontal static convergence. the tech will have to make a resistor out of 3, 6.2 meg resistors. | Muller |
