Question about Mitsubishi WS-55859 55" Rear Projection Television

1 Answer

2-3 error code, I checked the horizontal output transistor & all Horz. Chkts, all OK....prior to this error i was getting 2-2 so i changed the 2 conv ics and 5a. pico fuses, conv resistors all chk

2-3 error code is horizontal deflection.......i checked the horizontal output transistor and checked fine....prior to this error i was getting 2-2 so i changed the 2 conv ics and also found 2 bad pico fuses so changed them and now i get error 2-3 i also checked solders at flyback transformer and two T marked transformers and the solders are fine......what else can i check for error 2-3

NO POWER AT ALL


Hi
our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

When i turn on horizontal output tripping. B+ and low voltage ok


Hello
Check the LOT and Horizontal Output Transistor. If horizontal output transistor get shorted [collector to emitter or collector to base], this kind of fault will occur. Here there is nocollector to emitter short as B+ is ok. Check for collector to base leak. It is best to repalce the horizontal transistor with a new one, and switch on the Tv for a short while, say 10 seconds or so, and feel the heat of the replaced transistor. If it gets overheated, of LOT makes a whisiling of hissing sound, LOT is faulty, and shoul be replaced sith same type and number. OK.

H out transistor defetive & number missing plz solve


Hello

The horizontal output transistor number for Sony KV-ES34M61

Horizontal output - [Q6807] == 2SC5480-01
Pin output - [Q6808] == 2SC5480-01 Again

Please replace bothe the transistor at the same time. Check horizontal output transformer [LOT of HOT], for any defects.. Ok

SONY KP-61V90 tv will not power on, red light in front,


Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.
Thanks.

Mitsubishi ws-55859 projection tv with 2-3 error code


did you change the two pico fuses F9A04 and F9A05 when you replaced the Convergence ICs

The error codes...


a 2 3 code means horizontal deflection has stopped thats what is most likely shutting down your set. The most probable cause for this would be a defective Horizontal output transistor.

Will not turn on.


  • proceed as given after your power supply is ok (your statement)
  • isolate power supply from h/output stage.
  • check diodes & capacitors connected with flyback transformer.
  • check for print short.
  • ckeck h/output transistor.
  • connect supply to h/output stage.
  • put on the set.
  • hope this will help.
  • good luck

still there is a drop in voltage then your fly back transformer faulty.

Tv does nothing


ahhh the noise maker comes to life again .. Ok my friend this is a common problem with this set If your lucky?? If you know anything about trouble shooting tvs then this is what ya got.. Try first to measure the Horizontal output transistor. It will meaqsure a few ohms between the base and emmitter. But the base and collector should measure about 450 to 550 olms on the diode settings onm the metter.if it measures shorted you need to replace the flyback tranformer along with the Horz output transistor. Now if the HOT( thats horiz output transistor)is not shorted then theres a little coil in the horizontal drive thats causing problems as you need to take out the coil from the PCB and scrape off the ends and reinstalkl it. also the horizontal driver tranformer as well as the resistor that feeds the transformer could be bad and thast is a 3200 ohm at three watts. if ya dont have a clue what I just said the sets gonna cost ya ariynd 200 to 300 to fix .. Is it worth it to ya>?????lol Good luck
