Power Circuit I need to replace my power circuit. It's kind of impossible to find it here in the philippines. can anyone recommend a site where i can order it.

Flickering can be of many reasons. A fault in the power supply board too can cause this. Contact any service technician before replacing anything.

If the main fuse should blow up; surely there should be a short circuit to any component/s at it. If the secondary [DC] fuse also has blown up, there should be a reason for it too.
You should first check out the main power board alone, and then the secondary board connected. It will be impossible to follow these without its schematic diagram. Try to download it by internet. Without proper guidance; how can we follow the complicated circuits, and check the components?

There is some kind of short circuit to any of the component/s at its circuit board. Short-circuit protection circuit [built in] energizes and shuts off the TV each time you switch it ON. The fault location to this kind of trouble is a skilled work and not a user repairable one. It is best to contact any service technician. Its main power supply regulator section circuit should be troubleshooted. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

The board may appear undamaged, but the instrument's behavior says something is broken. I have no idea what kind of musical instrument this is, but circuit boards are all the same.

Especially on boards with narrow circuit traces and surface mount parts, damage can be very hard to see. A trace might have a hairline break which would be impossible to see without bright light, strong magnification, and some idea where to look.

It's also possible that the board is fine, but some part has been damaged. The lead from some part may have broken away from the circuit trace, for example. Or a small surface-mounted component may have popped off completely or had a lead broken off.

Unfortunately, this kind of trouble is very hard to fix without detailed product information (circuit diagrams and board layout). Unless the manufacturer makes a service manual available to the general public, this means sending the unit back to them or an authorized service center for repair.

I would recommend Shopjimmy.com.
Parts are at reasonable prices. Compare with the prices at Partstore.com and you'll see what I mean.

this symptom is usually caused by a breakdown in the power-supply circuit. in most modern receivers (transistorised and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (horizontal oscillator, pre-drive or drive circuits.). this is because the supply volatages for the tuner, video intermidiate frequency(VIF), video amplifier, sound intermediate frequency(SIF) and vertical output circuit are usually supplied by the horizontal output circuit. since you are not inclined with this kind of job, better bring it to a qualified tv technician. with regards to the cost of repair, i cannot tell you the price since my location is different from yours. but to give you and idea, here in philippines $100 is enough for this kind of trouble!
