    Same problem here, although until a couple of days ago, if you powered off the tv you had to wait a minimum of 10 minutes to turn it back on. Now 1-2 seconds and nothing but the on/off click of a relay.

    I took it to an authorized service shop and they told me it was the Deflection Power Board/Power Supply Board. They told me they could not fix it at the component level. Mitsubishi has a three year warranty after their 1yr they don't tell you about I learned it from Consumer Affairs. My TV is out of both warranties. The service store charged me $95 to look at it and wants $600 more to fix it. The Deflection Power Board costs $260, but Mitsubishi will not sell it directly to consumers.

Hitachi 52fdx20b TV; power light will not turn off when TV is turned off.


if power light is on most of the set inside is on.

Follow power cord inside set and on power supply board look for up to three rectangular black relays that are there-----they will be marked with relay voltage in white.

Gently tap with something not metal on each until the power light goes off.

What happens is one of the relays sticks in the closed position.

If the power light goes off when you do this the relay is bad and if there are three the part number is printed on them----replace all three as they each have only 4 solder connections and are generally under 10 dollars each (wholesale about half that).

If tapping stops it sooner or later it will do the same thing again.

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.

Samsung 50'' Plasma TV won't turn on anymore


If your tv is within the one year warranty period then call 1-800-Samsung for warranty repair. Look at your tv purchase receipt for the Purchase Date. You have one year from the date of purchase to get warranty repair.

I don't know why but this got my TV on.
I took off the back cover and found the source of the clicking.
Two blue plastic rectangular relays in the exact middle.
When I pushed the power button, I felt the top relay click, and I saw a flash from the bottom one. (they are right next to each other)
I took a hair dryer and placed it over the two relays for about 1 minute and tried the power.
It clicked only 4 times and then came on!!!!!!!!!
For some reason heat helps the relay.
If anyone is a tech and can explain this, please do.
Good luck!!!!
My tv is on and it didn't cost me anything.
I just can't turn it off now!!!
