Today's Plasmas and LCD are more challenging to troubleshoot to the component level as most service techs replace the entire assemblies.
I would suggest to start by measuring the voltages from the power supply to the Ysus and Zsus board, those voltages will appear for a short time since the TV goes back to shutdown mode. Check all the fuses on the Ysus and Zsus boards as well, any blow fuse will indicate that a transistor or mosfet has shorted out. Most power issues are related to the Ysus and power supply assemblies.

Just unsolder the switching diode on the right and switch it with the switching diode on the left facing the back, at the bottom of the power supply board, the one that clicks, works like a charm.

Toshiba 50hp95 will not respond and has flashing red power light. It seems many people have this problem, what's the solution? We have tried all the Toshiba suggestions.


My 50hp95 had the same problem; the red power light is flashing and the tv will not turn on. I unplug the power and plug it back in and the TV clicks, but the power light continues to flash red. My problem was a bad Seine module which you can bypass if you do not need to watch HD off air programming. Since I get my HD from the cable, I can bypass it. All you need to do is remove the back panel from the TV (unplug the TV first) and on the main circuit board unplug the white connector labeled PJ63A. The main circuit board is the one in the center of the TV and the PJ63A connector is the bottom white connector on the left side of the main circuit board (the label is printed in white on the circuit board under the connector). Once I plugged the TV back in it worked immediately.

50HP95 Toshiba Plasma TV No power but blinking power light


I had the same problem with my 50HP95 Toshiba Plasma TV. It would not turn on. I read online that if you unplug a connection on my TV and it turns on, it is a bad Seine board. I could not find this Seine board anywhere online. It was either out of stock or no longer available. The TV is just 5 year old. Why would they discontinue parts for it? Then I saw a video on You Tube where someone unplugged a connection in the back of his TV to fix problem. I decided to try it. I took the back off, unplugged a connection numbered PJ63A and the TV works again. So far so good. I downloaded the Service manual for this TV to find where PJ63A was.
I also called Toshiba Tech Dept. to find out if there was a chance I can cause further damage to my TV. They had no idea.

in protective mode the tv does not turn on and light is blinking, typically we must proceed by elimination as some faulty sections are preventing the tv to switch on. unplug the output power connectors from the power supply until the latter stop clicking. if it is still clicking after every of the output rail have been disconnected, then the power supply itself is faulty.

but anyway 3 circuit boards seems a lot to be replaced in a row.

hope this helps!
