SOURCE: power supply bad on Sharp Aquos LC - bad board - schematic to ID?

Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.

Let me know how you do Kathy ?

SOURCE: no picture

Had the same problem, Insignia 32 would click on then go off. About 6 months ago I found (somewhere on the net) a guy who explained that he changed blown capacitors. As I recall he even posted a picture. I found the blown capacitors and replaced them with larger capacitors (less than $20) problem solved...
But now my screen image is showing only half a picture and is pulsing on a off.
I think I'm going to make a Wii commercial......GL

My Sanyo HD TV power light comes on but no picture and no sound.


Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Help new power supply will not power up.


if you had a surge, it could have damaged more than just the power supply. When you plug in the unit, does the power indicator light up??? your main board could also have damage. The main board sends a signal to wake up the power supply thus turning on the TV. If you have to replace the main board as well, it probably won' t be economical to repair the set.

You need to find out if the power supply is putting out 24vdc for the backlight inverter board, it can be that the inverter board has short circuits which will cause the 24vdc to go into shutdown to protect itself, you can disconnect the power cables to the inverter board to see if you will get the 24vdc back.

50 inch Sanyo Vizon Plasma TV. Has sound but no picture for last few days. 2 years old


This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.

Quite common.

Repair estimates should be $250 - £350 depending on which has failed.

Stick it on eBay, it will fetch good money faulty.
