Question about Mitsubishi WS-65809 65" Rear Projection Television

2 Answers

Mitsubishi WS65615 65'' Rear Projection t.v. turns on then after a minute it turns right back off.

I have done Ic's before not on this t.v. though.
I'm sure I can do this though.
Any ideas what I should replace???
Or should I just toss the darn thing.
Thank you for your help.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Self-diagnosis error 2-3 indicating deflection failure. Check for shorted or leaky Q5A37 part # 260P818050 located on PCB-Main. If found defective replace only the transistor instead of the Main PCB.
also if the ligt on the front keeps flashing after shut down
Check C81A2, C81A3, C81B3 and C81B4 (1000 uFD, 16V, 105C) on the DM PCB.
If any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

It just click ON and OFF, right? If you hear the hight voltage noise tring start, may be the Tv has bad vartical IC or regulator IC. If you have no experience with electronic you will need a technician to halp you.

No Picture after it's been on a while. Audio OK.


ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.
