I checked unit, I pushed menu & input for error code 23, (which is no horizonal deflection) checked unit & pico, +24, -24 fuses were open. Stk was bad, replaced it & replaced fuses, still shows error code 23 & doesnot come on. It comes on for 2 sec, then goes off. Have high voltage momentarly using high voltage probe on flyback out.
Help, Any suggestions, Would appreciate any assistance
Thanks Vic
Get a schematic and see if the set is going into high voltage shutdown or over voltage shutdown in the power supply. Measure and monitor the + and - 24 volts at start up, make sure that both are there. Let us know what you find.

All standby votages r ok, ck 24 vote + and - at start up ok Ck all caps in horz board they were ok. Tomorrow will ck all caps in power board no bad parts found yet I have a diagram. Appreciate any help. Thanks Vic from Gun Barrel City
send me a copy of the schematic to techman32K@yahoo.com and we can go from there.

did you get the schematic for the mit. sw65511 I emailed you? If not let me know.
Must have gotten lost or taking the snail mail route

What does the error code read now Vic? I got the manual by the way.

Have you checked your B+ pins of your convergence IC's yet?

good morning, checked all voltages on stk, and everything checked out ok. thinking I had a bad stk, I removed stk & turned on unit, still won't come on. rechecked all standby voltages again. all ok. checked out parts on deflection board, everything ok. today I will change out the flyback. I don't have a scope, so I can't check signal. my scope walked off.
thanks vic
SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB . Before replacing the fly, as I have not had any of these flys go bad, Check all of the capacitors and diodes on the sweep power supply. This is the voltages the flyback makes for the rest of the set. also check pin 10 of IC%A)) for voltage. If there is voltage, the HV protect is on. Check for a shorted or leaky D5A60 in that same circuit. i found this 15 volt zener to be bad a couple of times.

Well I beleiveI found the probem on the ws65511. I took hi votage tripler out and disconnected the crt anoid, one at a time and tried it and when i got to the red one, the tv stayed on for about 15 seconds and blew a 110 volt pico fuse so I hooked the red anoid back up and Fay,sweety pie, with her great hearing said she could hear a lite frying noise. I took out the crt to see where it was coming from. I took the wrong screws out and fluid went all over the boards so you know what I'll be doing tomorrow ha ha ha, I'm hoping its leaking from where the anoid goes in the tube. I've fixed them before, clean it real good and put a heavy silcone on it . I'll let you know what happens tomorrow. Thanks for your help Vic
No it is not leaking from the 2nd anode, it is leaking from around the front or the lens attachment area.

are you talking about hi voltage or coolant? I was talking about hi voltage
Oh ok nevermind. You said something about the coolent and you hoped it was not leaking from the 2nd anode.

Hi Larry!
I have a Mitsubishi ws65511 and the tv has converge problems a wave coming down from the top and the green and pinkish red lines won't align. Someone told me that it was the eproms with the heat sinks on them but don't know which board. So I was reading your message about getting a schamatic and was wondering if you got it, if you could e-mail it to me at avvv1956@yahoo.com so I can figure out how to fix it
Thanks.
There is only one convergence IC in this model. It is the STK393-110. They are not eeprom IC's. The IC needs to be replaced and also you must check the small fuses in the main power supply that are marked F9A04 and F9A05. I will send you a copy of the service manual. Good Luck

victorcha, i noted in reading your thread that you have a schematic for the ws65511, i am having trouble locating this and was hoping you might be able to e-mail that to me. @ john_mcbride_2002@yahoo.com. i see you have had some issues with your set i have just started a thread in hopes of some expert advice to help fix mine if you happen to have anyadvice for me please check out my thread, post anything you think may be of assistance, thank you in advance.
