SOURCE: tv stuck on standby

Power supply probably needs to be replaced if you don't even hear the relay click after the power is switched on.

SOURCE: WONT TURN ON

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

SOURCE: samsung tv model no LE40R74BDXIXEU TV IS USUALLY

First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.

SOURCE: the red light standby is on but the tv will not

Your power supply board needs to be REPAIRED not REPLACED, replacing the board will just make the problem happen again in two years or less, if you can use a screwdriver you can send me the board and I will repair it for less than it would cost you to do it yourself ($50) with the correct components.

Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where in the panel board.if otherwise power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem....

I cannot get a picture on the screen of my tv. I have my tv hooked up to a digital cable box. The "source" for the tv has always been the "HDMI 1". For some reason that i do not...


Hi
Firstly and would remove all the leads from your TV and check them. If after checking your HDMI leads etc... and its still the same then i would reset the TV to the original Samsung settings. This is completed on your remote control by the following........

Turn your tv to standby, on the remote when in standby press the keys on the remote in the following order........ INFO.........MENU..........MUTE.........POWER ON.

You will now notice the picture comes on with the engineers settings in the background. With the direction keys on the remote scroll down to number 12 (RESET) Then press OK or the right direction key, Your tv will switch off and load the Samsung factory settings. Switch the TV back on and go through the setup procedure.Once completed then try your HDMI again.

If it is still failing then there is a strong possibility that your Eeprom IC on your main AV Board is corrupt and needs replacing. This should only be attempted if you have good soldering skills as they are Surface mounted and very small.
My advise if your skills are not that good is just to replace the main AV board (Scart Board) these usually sell for around £50 but WILL solve your problem.

I have gone trough everything i know here that would cure the fault, most times one of the above three will cure this, but im afraid other times its just time for a new AV board.

Hope iv helped some people out here.
Any comments or thumbs up appreciated.

If it's a big tv it can just take a little while to power up, I've found that pushing channel up button switches on tv quicker but I've no idea why.

Unless you want to save power you should only be switching tv to standby, there will still be a light on the tv somewhere, blue or red it varies. TV's turn on much faster from standby than completely off.

I have just bought a new wide screen Samsung TV but I can't work out how to switch it off completely. It always goes into standby mode


Have you tried pressing the standby button, and then the on/off button afterwards? Sometimes they need combinations of buttons, to work. It happened to me. I dont know if it will, but i hope this helps! :-)

try disconnecting the convergence board and see if it will turn on without this board connected - if it turns on then you likely needs to fix or replace the convergence board
