    This unit is a 1993 Toshiba 32" analog television. It is not a projection tv.

    This TV is a model CF3266A. It needs a STR55041T regulator IC. Where can I get one?

Try reset .

Unplug the unit from power chord for 30 minutes and plug back the power chord to the unit .
This will reset your unit .

    There is a short
    somewhere in the set . If you have a volt meter you can check the fuses to see which one is open. The fuse will be somewhat rectangular in shape and can be found around power supply board .

    Hope this helps .

    If you need further help feel free to ask .

My hitachi 46f500 tv wont stay turned on. you turn it on the red light comes on and then you here it click once then shuts off. It has done this in the past, then for no reason it will start working again.


This model like most of these sets uses up to 3 mechanical relays; they are black and square (follow power cord into set) and have a history of either opening or not when in use---I have seen several where it would not shut off or turn on etc where you could tap on the relay and the set would work..
The only other reason would be a bad solder connection in the same area---tap and the set works and it is either the relay or a bad solder connection.

The click is the relay shutting off and points to where your problem is.

If you have questions comment here and I will help.

Mitsubishi Medallion does this


hi there,

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

Panasonic rear projection model #- PT53WX53G will not turn on.


Happened to me, relays, either 1 of 2 so I had both replaced, about $300.00 to fix.

Mitsubishi Projection TV Model # VS-50502


The power supply section is having trouble.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

Power light doesn't shut off.


You're right. It's not only a led problem. Efective. the tv doesn't shutt off due to defective relay S901 in primary power supply. It's a 5 volts ordinary relay, replace it and it'll be fine.

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,

Power light does not turn off


This happened to me once and it was still under warranty. The warranty people came in and replaced a relay which seemed to fix the problem. Like yours mine seemed to work just fine when watching TV but I was worried that the power on all the time was putting undue wear on the components so that made me uneasy. Sorry I can't give you any more specifics.
