Just visit this link It has details about convergence procedure to rear projection television. Convergence adjustment procedure to most brands PTVs will be similar. Pull up older posts there, by its left side bar. http://electronicshelponline.blogspot.com/
you need a service remote and a cross hatch and pattern generator. you may also need the service manual for the set in question because this will guide you in the proper way to re-calibrate the tv to factory specs. the above list items are very expensive unless you have a repair shop these won't do you much good for a one or two time thing. your best bet is to take to an authorized service center or a qualified repair shop that can re-calibrate the tv for you.
The HD61LPW42 is a RCA DLP which doesnt have convergence. If the convergence is out of alignment you have a three CRT TV such as the D52W19, HD52W59 RCA Check the model number from the rear tag and let me know what the model number is.
tHIS is a convergence problem.. first question if you go into the customer setup menu. is the convergence option listed? If you have not got that option i suggest you read "the fl231 problem in the tips and trick section of this website. this can be a simple inexpensive repair..if you do have the convergence option then it can be one of three diffrent boards convergence power, convergence amp or small signal board. and will need further trouble shooting
If the convergence is out on that set you most likely do not need to make an adjustment the circuit will need to be repaired. There is a stk on the convergence amp board that needs to be replaced. A good tv shop will run you somewhere between $300-$500 to do the repair
Use a site like servicemanuals.com and get the
service literature for your make/model.Do NOT
perform factory reset procedure-that is reserved
for when certain parts are changed.You will need
the access sequence,adjust info and add to memory step for servicer convergence.Keep in mind--you may have defective convergence IC's.If so,you will
have difficulty w/alignment.Use OEM or better IC's
no generics!! They won't hold up.
