Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

First, You should to replace by original part, then you should check the voltages on power supply, and check the voltage for vertical IC based on datasheet, also check the voltages on vertical section including yoke and last you should check the ESR capacitors on vertical section.

In a standard set the power supply produces one large voltage and a few smaller ones---if the High voltage circuit comes up it creates the rest---this answer is based on the description that this is a set with a picture tube and not a LCD set.

Panasonic TV TC-21FJ20R is a big blunder of Panasonic Company, shame for Panasonic company to launch this type of product in a huge price.

damage can be ascertained from the power regulator, you can check the transistor / STR power regulator, and Diode Bridge (AC-DC), check the Positive and Negative on Elco 220/450 volt power regulator, is there a short circuit? if no, probably from before entering the diode, it can be from thermistor. Hopefully help

Hello
Your Tv has verical shift problem. It is not the supply problem. It can be got repaired. Sometimes it may be the fault of chroma Ic. In panasonic telivision the chroma section has an ic and it is surface mounted. We will call as SMDs. An SMD replacement needs special tools, which a normal sevice mechanic can't afford. So it is best for you to contact the authorised sevice center of Panasonic nearby.
