I have an RCA HDTV 52 in 2005 model that makes a humming noise picture color starts jumping in and out from color to blk and white then picture totally goes blk, then after a few minutes will come bk on....

with the symptoms id start looking in the High Voltage area for a Multiplier block failing or possible fly back transformer and i would not continue watching it ti the problem is isolated and repaired as this can further damage and destroy a video processor IC or other parts but id suspect a multiplier block or high voltage tripler is another name for it it is its accesable from the front by removing the speaker panel and be CAREFUL as there is High Voltage present there and you could get a Nasty Zap

When turning TV on it would click a few time, then you would hear a hissing sound, but no picture. Would have to unplug TV, as it would not power down. Unplugging and plugging in would eventually get...

The hissing sound could be high voltage leaking from a tripler. Observe in a dark room for blue arcing. Look at tripler and connections to the projection tubes. If the tripler is leaking replace the tripler.

Light on switch goes on and off 3 times but t.v. does not go on

The regulator transistor or chip may be shorted or the high voltage shutdown circuit is shutting down the set. A defective high voltage tripler can also cause this condition .

Have a Toshiba TP50G50 Projection televison with no picture. Have 100 volts to power board

100 volts is too low to power the entire projection TV. Usually with rear projection TVs there are three tubes that create your picture on the screen. To power those tubes, they each require a high voltage (usually around 10,000 volts - yes ten thousand) that is produced by a high-voltage step-up transformer call a 'Tripler' - since it powers all three tubes. This device and the rest of the TV require full utility voltage (120 - 130 volts AC) to properly power the unit. Correct the voltage and try again - is the house / residence voltage like that in each room? IF so, you probably have other issues with devices you probably haven't picked up on.

No picture

Hello waylongross,

This might be an indication that your voltage tripler have gone bad. You will have to use a HV probe to measure the voltage on the anodes of your Red Green and Blue CRTs to see if there is HV present. Then you will have to measure the voltage off of the IHVT (Integrated High Voltage Transformer) to see if it is delivering the proper voltage to the voltage tripler. If there is not HV at the IHVT then you will have to check the HV and Horizontal Circuits for a problem.

If you do not have the equipment for these checks I would advise that you take the TV to a qualified TV repair shop or have a technician come to you place to check the TV.

I hope this helps,

Thank you,

Toshiba TP55H95 Shutting Off

the power supply board may not be the problem as that only provides the voltages that go to the other areas of the chassis. Where as a manual will explain where the voltages go and what has to happen for the set to start. the power supply could be good but a leaky diode on say the signal board could allow voltages to increase thereby shutting the set down. Unless youre really good at troubleshooting, I would highly recomend getting a manual.
