Question about Toshiba TW40F80 40" Rear Projection Television

1 Answer

Tw40f80 with blinking power light

My tw40f80 goes into protection mode as soon as the HV supply tries to come on, i hear the high frequency the flyback generates and about a half second later it clicks into protection mode and the power light blinks, do you know of a reputable place to obtain the service manual which will have the circuit diagram for the power supply sections of this TV?

I replaced both convergence IC's and their large low ohm resistors already thinking that they had gone bad, but still having the same results, none of the fuses in the power supply section are blown, already removed them and tested with a multimeter, they all check out fine.

Mitsubishi WS-55511 - No Power - No Blinking Light


This can be a problem with the powersupply of the television that's why you hear a high frequency noise and there's no power or any light coming on , the power supply may gone bad and needs replacement..

Good luck.......

Timmer keeps on blinking,cant turn on power


Check for 160v on your power supply to see if working. Can you hear high voltage? If not, check for 130v dc on your horizontal output transistor to determine if power supply or hv problems.

Hi:

You are in HV shutdown mode, Have the Horizontal output transistor replaced as well as the Horizontal output transformer. These are the most common failure for this problem, The three blinks indicates Delfection problem, and these parts are part of the main High Voltage Deflection circuits.

Is the t603 and r672 part of the tv or the actual circuit breaker


Three blinks - B over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

DOES THIS ABOVE issue have anything to do with Cooling FAN?
I cannot hear the cooling fan come on when first turned on like
before THANKS

Sony 50 Wega LCD flashing red light


Hi

How many times is the red light flashing? The number of times the red led blinks means---


  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.

  • One blink - not used for the self-diagnosis

  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.


  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
  • No blinks(Unit is dead) - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
Please do rate this solution as FixYa and revert for further assistance.

Thanks

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
change......

No powering up


2 blinks is +B OCP protection. The manual states "Short circuit of power supply system in each circuit." and "Goes to the standby mode. Short circuit of +B line"

Sony Big Screen TV Not Powering On


This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,
