Either the Standby voltage is missing or the main board is defective.

Three blinks to standby light to Sony LCD TVs, denotes a fault with its main power regulator board. If the set is in warranty period, contact the authorized service centre. If you wish to know more about this fault, http://electronicshelponline.blogspot.com/ check this link. Pull up older posts there, either by its left side bar, or see it in Timslide option.

Buy a new TV, CRT sets aren't worth repairing

The service manual lists 4 blinks as "Fan Stopped". Probable cause is - "Fan 1-4 power is not supplied. (AGU board) - "Fan connector is not attached securely." - :Fan caught wires or harnesses.
I had this problem recently and I was able to clean it up and get it running again.

Question edited for clarity and spelling 'board' - 'different'. If the board number is the same, yes you can use it. The likely issue is whether the board is new or taken from a scrapped set and whether it is returnable. https://www.fixya.com/support/r29790007-repairing_own_television ..

moved you out of computer repair it is not one. first off the remote can be failing !! first try fresh new batteries also if kids spill drinks on the remote the buttions can fail even turn on , not touched. turn TV on , and move the remote to farthest room. see if TV stays on. or turn on TV and remove remote battery fast. ok now, yes/.no// some TV have no on button or is the only one on the TV, I really do not want to read your manual but if there that button on TV> (on/off) remove the remote batteries then turn TV on with its only button, on side of TV cured? super simple tests, to do no? and super effective facts learned and even cures based on results. ok read you manual see googled in 5 seconds and yes center right bezel LCD had Press 1 on the TV to turn on the TV any remote abuses or got wet will fail. easy, take out the batteries, push 1 above.

Remote codes are purely based on the make of the television and it is irrelevant what the remote is. However, I would say that no one these days buys universal remotes. You buy a Facsimile Remote which is an exact copy of the original.

It could be a problem with the power supply for your TV and a bad power supply too. You would have to have a TV repair person to take a look and see what the problem is with the TV.

I'd lean towards a bad panel or tcon board, I don't think this is a main board issue

Needs new lamp or the fan is out.

Check the LVDS cable to be sure it's connected properly, also unhook the 2 ribbon cables going from tcon to panel boards, clean them and make sure they're plugged all the way in. If that doesn't fix it you could try replacing the tcon, if that doesn't fix it unfortunately your panel was damaged when it was handled, this happens quite often, in most cases it's from static when it's carried from one point to the other while replacing the strips.

going into stand by mode means amplifier out put are bad or blown fuse

hello sir

It is here https://dokumen.tips/documents/urc22b-universal-remote-control-manualpdf.html ...

It doesnt guys.I already tried it.Only supports .mpeg and .dat files.

Did you try changing the batteries in the remote for brand new ones fresh out of the packet?

Do you get voltage with the main board unhooked?
