I have the same problem. The fuse blows every time I plug the Sony STR-DE135 into the wall. I did not find the F901 at Radio Shack, so I bought a fast acting 5 Amp 125V Fuse at the Hardware store. It blew...


There is usually one or two normal clicks on power-up. A self-protection relay activates after a short delay for circuit and power stabilization plus some internal cheking for shorts and thermal issues.

If it keeps blowing fuses you are stressing it a bit more every time you feed it another one. I'd get it in to a Pro for repair.

Sony str-de845 Powers up, relay clicks, fuses BLOW!


This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

No Power


all sets must have rated fuse for protection. some units now use what is called a PICO-FUSE.this type of fuse is soldered into the pc board. usually marked with location i.d. F301,F901,F400. etc. these fuses look like resistors or in-line coils. check continuity w/ohm meter. if new fuse blows as soon as you plug in tv, suspect bridge diode ciruit or main filter cap(large ripple filter by main fuse. if new fuse blows when you try to turn on, suspect 130v regulator or high voltage short(horizontal-output, flyback transformer) good luck!

Iris problem with PT-AX100U projector


le probleme est du par les pivots de l`iris qui manque de lubrifiant. il a deux pivots a lubrifier, le premier se lubrifie sous le projecteur dans le compartiment de la lampe.
il est de couleur brun et il a un petit resort autoure de lui, il est en plastique. prendre un micro
tournevis et le faire fonctionne. il doit revenir sur lui meme rapidement,lentement pas bon il faut
le lubrifie. seulement une petite goutte suffit.
le deuxieme est plus complique,il faut ouvrir le projecteur. les vis sont sous le projecteur indique
par des fleches. il en a une autre sur le dos .attention il est difficile de separer les couvercles
on peut voire le pivot sous une petite grille de metal il est brun lui aussi

ps prendre le tounevis pour applique le lubrifiant atf dextronIII

The fuse is good if you're still seeing some kind of light on the front of the LCD. There might be defective capacitors in the power supply and that is why the LCD is not powering up, but also there is a possibility that the back light inverter board might be defective.
Let me know if you need further assistance.

Mitsubishi console TV Model CK2689R


Your tech could be correct... These were GREAT sets in their time and many are outlasting sets half their age.. When Mitsubishi announced in 1999 that they were discontinuing direct view manufacturing because they wouldn't compete in a throw-away market I was a bit sad as a technician because they were the cadilac of Tvs for how they were built. But alas everything does come to an end...
I would suggest checking the fuse at F901 for open. If it's open then it's likely C587 has failed and the horizontal output transistor. If F901 is intacted then you would need to do some trace testing with a scope to see past the smps what's happening to your power. You might try researching the NESDA site for a nesda technician near you. http://www.nesda.com/locator/state_search.php
Hope this helps!
