Question about Mitsubishi WS-65809 65" Rear Projection Television

1 Answer

65809 and the light comes on for about 2 seconds and turns off.

I have checked resistor next to the power supply (47 ohm). I'm sure there must be other symptoms.

I need a stk-392-100 part, I would like to know what the blue resisters are next to it?

correct part should be STK-392-110 and most of the light blue resistors that fail next to it are 2.2 ohm 2 watt.

My mitsubishi ws-65809 will not power up.

Mine is doing the same thing. I just talked to the repair guy. It is a power supply problem. Try unplugging it for 5 minutes and turning it back on. Also if you were having problem with any picture issues it is the convergance, and that requires chip replacement. They are estimating $350.00 to replace the power supply.

TV will not turn on

Replace shorted Q431,can use a 2sc3998, open r448 .47ohm resistor. after you get set on beware of convergence ic's may have been shorted causing all the problems.Check r859 &r858 .47 ohm 1 wtt that supply - &+ 20 volts to convergence packs, if open replace packs & check low ohm resistors on convergence ,I found r2144 &r2145 open replaced & all systems go "good luck"

Good Day, 4mlspro;
You can try this or call an Authorized Service Center and get an estimate on the repair, $450.00 to $650.00;
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. 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 (NOT SHOWN IN THE SCHEMATIC). 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

Toshiba tw40f80, replaced both convergence ic's, power light still blinks

Solder yoke plug and vertical IC connections.....try again.
Let me know.....T.

BTW....Tosh recommends STK-392-110's replace with -110T's
Toshiba OEM.....then there is no question about resistor value

Sony KP-53V75 53 in. Rear Projection Television

I am not sure exactly which power supply that model uses but here is what I usually do: Remove the power supply board and be sure to discharge all of the power supply capacitors. Look near the large cap(s) and AC rectifier for a small white resistor whose value of 0.1 ohms is printed on it. That is your power supply fuse. Measure the resistor and if it is open then you can bet that the switching transistors are shorted. On older sets there are 2 separate transistors (2SD4834) and the newer sets have the 2 transistors combined into one 6-pin package labeled MX0841 or MX0842. If you find that part shorted then replace it and the Sony 0.1 ohm "fuse" (use exact Sony replacement parts) and your set should be fine. If you find that the 0.1 ohm resistor is good then there is a much more serious problem and the set should be serviced by a qualified tech experienced in Sony sets.

Bad Component

Hello Lee. I have seen that many, many times. There are 2 large black convergence IC's, STK392-110 and one of them has shorted out. The extra current it is drawing is cooking the resistor next to it and the computer senses the extra current and shuts the set down. The part you see glowing is a 2.2 ohm 1 watt (or 2 watt)resistor, the same as the 5 other resistors next to it colored red, red, gold. You need to replace the convergence IC that the burning resistor is connected to and replace that resistor, and your set will then work normally again. If you have no experience replacing convergence IC's then have a qualified tech handle it for you.
