My Sony KDS-R60XBR1 60 inch HDTV came on for a few min then shut down itself, and the power/standby led blinks in a 7 times mode (7 times then 7times then 7 times ... ). I read thru the fixes on this site...


Ok i have consulted the shops service manual on that sony model.A blinking led of 7 times is and indication that your audio cuircitry has blown. or shorted. most likely the audio amplifer ic. ic number 3005 on the K cuircit board. Specifically the audio power supply line has become shorted. most likely it would need replaced along with its assocated fuse ps3001

Tried to auto adjust the guns, will not come within range


Hi Tod,

If colors do not align correctly, most likely you have a convergence failure. This requires replacement of the 2 STK ICs and possibly some low ohm resistors.

Some Toshiba have a Horizontal oscillator/Drive IC failure that results in a small or shrunk picture (2-3" border on all sides). The 3 colors do not align properly because of the reduced Hor drive signal. The convergence adjust controls will work but not allow good adjustment. Convergence is ok, Hor Drive signal is incorrect.

Many do-it-yourselfers mistake the Hor Drive problem in Toshiba RPTV with convergence failure. Too much adjustment of the convergence controls may cause the saved data to be really messed up and require more difficult alignment in the service mode.

If minor or simple adjustments in the customer convergence adjust menu do not fix your problem, there is a fault. Stop adjusting until fault is repaired

Convergence failure can be accurately identified with the Convergence Gallery on our website. Service in Toronto, Ottawa, Calgary, Edmonton and other Canada cities.

Blue Convergence problem


The convergance amp has failed and should be replaced there are two of them and also some resistors in the same circuit may have opened. if you tried making adjustments in the service mode you might have set the data too far out of the tolerances of the amp current draw and it may fail again. unfortunatly there is no way to reset this to factory reset to undo what you have done in the service mode. I hope you didn't write the data that is your only saving grace. the convergance amps are the stk392-560 sony part # 8-749-019-08. if you are not a tech it would be difficult for you to replace these have a tech do it or at least assit you.

Service Mode


JustinMan, if you use original IC`s (not the el-cheapo chinese copies) the odds are good you will need no or minor adjustments which don`t require the need to go into service mode which you really shouldn`t go into unless your experienced with tv repair, you should be able to order the serv. manual here, www.partstore.com it will give you the parts list and set-up procedure, good luck, BMW Rider

If you have a problem with the convergence, believe me, going into the service menu and trying to correct it will only give you large headaches, DO NOT USE THR SERVICE MENU UNLESS YOU ARE A TRAINED TECH!!!! Doing so can result in a complete and total failure of this TV set. I service menu is not for any major changes in any adjustment. It is not the cure all. If your convergence all of a suddenly shifted, it is not a service menu issue. Your problem is the convergence amp IC's. Good Luck

Help please stuck in service menu


You should have purchaced the service manual before you went into the sevice mode, as the service mode is a dangerous place to be if you do not know anything about it. You can get the service manual from www.servicemanuals.net for about 20 bucks or so. A lot less expensive then a serviuce call I would think.

Won't lock on standard resolution


LOL No such thing my friend. Thats what happens when you mess with the wrong buttons I'm afraid in the service maode. You will need to go back to the service menu and start over from scratch in the other scan modes. Sorry, no magic bullet
