I bought this tv about a year ago with bad ics and I am finaly ready to attempt to replace the ics I checked the pico fuses under the ic fins they are ok is there anything else I should check. Model kp51ws510. I have the board out just waiting for the ics. Thank you for any help.

I'm not oerfect but I do my best. That's all we can do.

Hello Larry,

Could you send me the manual as well, i have a Sony KP51ws510 with the same convergence problems that have been described, my email is witt@telus.net

I'm completely green at this sort of fix but i'm willing to give it a whirl.

thanks for your time. do you know of any video's that help in this fix?

thank you for your advice on the removal of the Sony second anode wire, yes it does explain several times on how to easily remove that pesky large red wire and yes if you yank on it first most likely you will have a very hard time removing the wire. I have mentioned the removal tool several times also but also mentioned it is really not necessary to have as as many as i have removed I have NEveR used one to remove the wire!!!!!

GOOD LUCK!!!!!

sure JP, here it is. actually if you go on Sony.com and punch up the D board part no.#A1302708A it will bring up the page for it stating it is discontinued, but shows a price of $65.00. you need to call the Sony repair center in Mt. Pleasant Pa, and talk to Jennifer Rohlfing. she will give you the low down on what to do. the phone number is (724)-696-7297.my take on this is that Sony either feels guilty or obligated or both {in my humble opinion} to its customers and owes it to them to keep them happy and coming back. im a Sony fan for 20+ years, and was fortunate to have this 6 year old set given to me, so if i invest say 80 bills in i... the 65 plus shipping etc...and it hopefully lasts a year or two, i can't complain. i just wonder that how we need to use the original Sanyo stk's why did they have such an early failure rate? i trust all the experts that warn not to use cheap 6 dollar knock off imitations, i just hope Sony doesnt do the same. 65.00 is awful cheap, so i hope they do a turnkey repair job and get me going again. while im here does anybody know how to properly test the pico fuses??? is a continuity test sufficent or do you need to check ohms etc.? all my D board picos had continuity but i want to make certain because i have two more to check on the G board as well. all in all its been very interesting learning something new, without getting jolted as well!! myany thanks go out to Larry D and everyone else who has taught and walked me through this.....this site rules!!!!

hi i was just wondering if there is picos on any other board that i should check before i replace the ics and plug it all in. i dont want to wreck the new ics before i even get to watch the tv. lol. every thing checks ok on the board with ics. thank you for any help

the testing of the picos is a simple continuity test if it measures no continuity the pico is bad it should also measure zero resistance

crownrock, my 'G' board had two blown picofuses: PS5001 and PS5002, both 5A, feeding the +22v and -22v voltages to the STK chips on the 'D' board.

I replaced my stock ICs and now the tv won't turn on. I press the power button, then the tv clicks, the red light flashes eight times followed by four quick flashes, and then clicks again. After the last click the light will continue to flash a sequence of four flashes. Any help would be appreciated. I reconnected everything correctly and checked all of the fuses before I put it back together. Before I took it apart it would come on but had a convergence problem.

I've been reading up on Tv issues for a while and I was hoping for a little clarification. Sometimes when you turn the TV on it will work for a few seconds, maybe 5-15, and then a blue screen flashes for a fraction of a second and it turns off. After it stays on it will work until you turn it off again. I have been looking at convergence issues because it also has the blue "rainbow" lines occasionally. I've read other posts that indicate it could also be a tube issue, because of the flash and shut off. Model is a kp-51ws500. Any help would be much appreciated.

Larry,

My KP51WS510 is having the same convergence issue and I thought about throwing it away but was lucky to find this site. Hopefully I can fix it or have it fixed with a cheap price. I read the first 50 posts and saw that you sent out the service manual 2 years ago to help out with the fix. Are you still doing that? I don't know where the D board located.

Thanks.

hi,,i just had my D board repaired by Sony and bench tested,,,and still have the EXACT same convergance issues...i checked the 2 pico's on the G board and they have continuity. also before i sent it to Sony i checked the D board pico's and they all had continuity........{i figure if continuity passes thru they are all good}? am i mistaken? one question is, and i know Larry stresses it alot, is "did you plug in all connections"? i did... BUT theres one, im sure its in its proper place that is bugging me. its gray runs from the metal strip of plate above the big distribution block {maybe a ground plate}... a thick flat black wire plugs in beside it on the metal plate ... well there is a single gray wire that plugs into the D board, and at its end is a gray plastic bulb and it has a white 4 pin connector and a tiny loop of white wire on the 4 pin connector. there are 2 spots on the board {one black 4 pin mounted on the board right at the very edge where the back panel mounts up, and a white 4 pin mounted on the board a little further in {few inches} that are both 4 pins. im quite sure the gray wire with the bulb and white connector go to the white 4 pin mounted on the board, or am i wrong? its odd the gray wire plugs into both 4 pin connectors,,, but i should have payed closer attention. i havent tried it in the black, only the white, and the tv is still the same, i just dont want to fry the board if i plug it in the wrong end. im sure Sony did a good job and checked the D board out completely .....hopefully its just a bad pico on the G board....or plugged in the wrong 4 pin? would the wrong connector cause it to bow-tie and 3d color still? is there anything else on the G board to effect convergance that i overlooked? ALSO the heat sinks were still cold after at leat 45 mins of the tv being on. i tried to auto focus and converge adjust as well ....no help ill try to take a picture of the board to show the 2 4 pins in question,,,,hopefully someone may know the correct placement. ANY help is GREATLY appreciated.thanks to all

I just opened the back on mine and saw that black plug-in you are talking about. I must have missed it before. As I said I never worked on this set so your guess is as good as mine! Please let me know what you find out as I don't want to hook it up to the black one and smoke the board! Does your tv play a DVD player clear but fuzzy on the tv with cable?

Yes, that's the first thing my brother told me to check. He's loaded with money so I have to work with junk, he just goes out and buy's a bigger one! I have all the manuals and parts list and all that stuff, it's to big to email but I can give you the links to download them if you need them.
