Circuit diagrams to many popular TVs are given.

Fault with the main power supply regulator 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.

There is a short circuit in its main power supply regulator board. Check and replace damaged component/s at this board. Never put a fuse and switch ON the TV, until all the faults have been repaired. It might make things wrong. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

There should be surely a short circuit in its main power supply regulator board. Without rectifying this fault, never insert an other fuse and switch the TV on. It might make things worse.

What is the problem you faces with this TV?

Hi alscyber1,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, try online like ebay.com and shojimmy.com.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

My TCL 21E20,,when switch on, giving vertical line on the screen for about 3 sec. and then switch off again.

hello i want to know about TCL 21e20 power ic regulator description about the ic coz i the ic is broken i cant read the description please help me

A nice little Control IC but when they fail ithey take out a lot of components around the power supply especially the output FET rather catastrophically for the power board.
I would look elsewhere for your fault because if there is a flashing light, the microprocessor has power and that comes from the power supply.
Look for open circuit fuseable links.
Hope that helps.

If the IC your talking about has a designation number of IC601, the number is MX0841AB-F. Common regulator IC. Sony says that IC is no longer avaialable. You may get lucky and take out the entire G board and have ptscorp.com, or Tristate.com repair the board for you. Good Luck
