No Picture_Panasonic PT-47WX53

It seems like I have the same problem as you described to another member, something dealing with the high voltage system. The picture suddenly went out and now I have sound but no picture instead I have a faint line down the middle of the TV. Do you have an estimate of how much that would cost? Yatrik

Your problem lies with one single component that has failed. It is a capacitor in the HV area that is either shorted or open. The part is quite cheap and should only require one hour of labour. Judging by the labour rated these days, you should not expect to pay more than $100 for the repair.

No picture, sound ok except buzzing noise, some light in vertical stripe center of screen

your vertical drive would have failed or lost connection in the pcb.Only if you are familiar with high voltage electronics do attempt. or else this could be aminor issue , to resolder the vertical drive, vertical power failure or drive. A quick votage check into this vertical section will confirm and the sweep can be retained.

No picture

Petty vauge possible Flyback/horizontal. since you don't get codes.. I would start with checking for +210 at D519, or look for high voltage.

Hello dana1983165,

The problem you described is caused by poor voltage regulation in the High Voltage power supply. This can be caused by a defective fylback transformer, a defective focus block, a defective HV trippler, of the horizontal output transistor/damper diode assembly. I would first check the high voltage from the flyback to see if it was fluctuating, you can do this with a high voltage probe. The I would check the horzontal output transistor out of circuit with a transistor checker to see if it passes.

If you do not have equipment what you can do is remove the deflection/HV board and order a replacement from panasonic.
Look up Panasonic's web site and contact their technical support number and call them to find out the part number and have them order the part for you. If this fails try PTS at

I hope this helps

Picture shows only about a 2-3" blue,green,or red vertical line down the middle

If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Panasonic PT-47WX53 Horizontal Picture Size

Normally, when I see this problem in the customer's home, I find the main culprit to be the cable or satelite receiver box. The remote for the cable box may have a button on it to change the format or picture size. You may have to go into the menu of the cable box to change the format setting. Hope this helps.

Panasonic PT-47wx53 screen converged to middle of screen

This sounds like a classic High Voltage problem. Yes the two issues are related. Something in the High Voltage circuit has failed and originally caused the increased size. If you described the problem to the warranty people I'm surprised that they didn't recognize the problem and fix it under warranty. Now you have a short or partial short in the same circuit causing the fault (light blinking) after a few minutes. This problem will not cure itself. As I have told customers in the past "Electronics are not human and will not heal themselves". Maybe in the future, but not yet. You need a technician and it should be covered under warranty if things are as you described. I would recommend calling Panasonic customer service. They are usually a very good customer oriented company.
