These numbers look like the ones on the parts themselves. Not the easiest way to find parts. Can you post the make and model as well as the circuit designation of the parts you seek? The transformer should be marked Txxx on the board and the relay will likely be RYxxx.

Sony STR-DE575 connected to 220V

Doubt the main pcb needs replacing, but the standby transformer would definitely go in that situation. Standby transformer wouldn't be that expensive, but no way to say that it's the only thing that is bad. It is also soldered in, so you would need to know how to do that to replace it, or bring it to someone who could. If you're staying long-term in Europe, it might just be better to buy something local so as to not run into this problem again.

Got a jamo avr693 amplifier the stanby transformer died .took it to shop for replacement but i was asked for its voltage which i dis not know can you please investigate the voltage for that little tr

I suspect that there is not a single standby transformer. Seems like a waste to have two transformers to power the same system. Your input voltage will be 220/110V depending on country. I also think that you need to look for a faulty IC/relay. Because most systems like that has a circuit for main power on and standby fed from the same power loop, main diff being that the moment you press main power on it energises a relay that self feeds and switces the main power on. Look for faulty relay or IC.

My TVs power supply transformer seems to have fried the fuse blows instantly. Is there any way of getting a new transformer? Th numbers on the it are LTT4PCOXB002, BCK-50-0006, and 8070372.

your tvs samps transformer may has no problem. the fuse blows because there is some other components which drives the smps transformer may be faulty. check the smps driving mofets of that three transformers before buying a new transformer. also check the MOV placed after fuse. if it is shorted the fuse will blows.

I bought SH-GE90 DSP And I pluged into 240V source while the indicator was on 110v and now its not working will replaceing the transformer will help or it just simply gone.

It is not possible for us to be able to determine the extent of the damage. It is possible that only the fuse has been damaged. It is also possible that the rectifiers have been dmaged. The bottom line here is that there needs to be some examination of the unit and some testing of the internal components. The best case will use parts in the $5 range. Worst case you are looking at $50 or more in parts. If the cost is not too high, take this to a servicer and ask for a detailed repair estimate.

The dislay flickers SH GE90.technics .it seems to be a common fault.. can this be fixed

replace the 3 electrolytic capacitors in the power supply section near where the lead from the transformer connects to.
they're sat side by side.
you may notice only 1 might be leaky but replace all 3 for good measure.

i've had quite a few with exactly the same fault and all were cured by replacing the above.

hope this helps?

Sanyo tv ds25390 buzzing sound

I had the same problem with the same model.
The solution was to replace a capacitor, C622, which is located near
a small blue rectangular plastic component.
This component is a relay that is controlled by C622. I paid $2.39 for
the part, $8.99 for S&H for a total of $11.38. This fixed my problem!
