46h84 toshiba rear projection tv

Without any pattern my tv will turn off while in use. After unplugging then reinserting the power cord the tv will play for a while and suddenly turn off again. Red power light will begin to blink after the tv loses power. There is no sign the tv is hot according to touch. Also there is a small distortion of color in the middle of the screen, this happened recently after the tv began to shut off on its on. I would like to fix it but am ignorant in tv repair and would rather not be taken by a servicemen. Any suggestions?

Herringbone pattern at turn on clears as it warms up.

Does your TV show red, green and blue colors separated?

If the answer is yes, the problem is in the convergence circuit.

There are 2 integrated circuits (STK392-XXX) that need to be replaced by a qualified TV technician. The repair will cost around $150 or more.

My 46h84 turns off and i have to unplug and replug

Good day!!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

I have a Toshiba 46H84. We had a lightening storm one night and the next morning the satellite dish and TV were turned off. DVD player was not and worked fine. The satellite dish needed to be reset, but...

Yes, all sets are protected by a fuse where the power cord enters.

Start at the beginning--unplug the set and look for the glass fuse--should be a 5 amp or greater. It will be in a plug in holder. If you are lucky the strike or power outage got it.

Do this with the set unplugged.

Let me know what you find---I am here to help.

Total loss of power to the set indicates either the ac fuse is blown or the the power supply is damaged.

Unless a tech actually opened the set and looked at it he is just throwing darts at the board.

I am here to help--if my suggestion informed you rate this solution as "very helpful" as I do this here for free.

REGARDS, SD TECH

Toshiba 46h84 rear projection shutting down

I have a Toshiba 46h84 with similar problem that needs a new green crt. Mine does not have a cooling fan. I don't know if having a cooling fan would help the problem, but mine didn't come with one. There are rear projection TV's that have bulbs in them that require a fan. This particular model uses a red, a green, and a blue crt to generate the picture and probably doesn't need one.
