Question about Mitsubishi WS-65819 TV

1 Answer

The tv does power up at all, we need a new micro-processor board

I am told mitsubishi does not make a replacement part for the micro-processor board. This part is the brains of the TV that is very uncommon to not work at all. Is there anywhere I can pick up this board.

Need help with a mitsubishi big screen tv. model #- VS-45605. It needs a replacement screen and has vertical hold issues.


You will have to search for a TV repair shop, and see if they have another 45" Mitsubishi TV of the same model, or close. You may be able to get a replacement screen from salvage. As for the vertical hold, in some cases you may believe the vertical IC is at fault (we will come back to this), may be not. The first suspicion is in the signal board. The signal board is the board with all the RCA jacks and RF connections. Pull this board out and replace Capacitor (location C2V29) this is a 16 volt 22Mf capacitor. Also replace C2P05 which is a 16 volt 100 Mf cap. This will correct your vertical problem. If you can find an ESR meter, I would certainly check all the capacitors in the signal board. You will find several weak capacitors to replace. The two already mentioned are extremely weak or bad. As for the other board (power supply) you may have to resolder the pins on the vertical IC. It will be located on the corner of the board. I do not remember the location. It is mounted on a heat sink, the vertical IC will have a number such as LA78XX. (LA7838, not sure). Resolder the pins on this IC and check the capacitors in and near this IC. I have not received much problems with this power supply. As always, inspect both boards for bad solder grounds and resolder as necessary! Thanks for asking and show all hands of support!

Sony kv36xbr450 - menu screen comes on and off by it self. It's not remote control. I checked. How can I fix that?


HI
This may be due to a faulty A Board, one way to verify is to disconnect the keypad from the main board and check if this is still happening, if so then the A-board is the problem, this is the board with the microprocessor is on, The micro processor may be faulty. you can try resetting the unit back to factory default by starting with the tv power off then hit the DISPLAY button on the remote then Number 5 , then Volume down then power button, you have to do this all within 5 seconds or it will not work. Once you are in the service hit the number 8 key to reset, TV will shut down and come back on by itself and be on channel 3. Any setting you may have set will be erased and the unit will be back to factory as when you brought it,. IF this does not help then consider replacing the A board. It my not be avaiable any more in which case time for a new TV..
