Re: 20" Samsung TV

The newer ones had a resistor parts change in the primary part of the switching power supply probably a yellow banded resistor for startup

Sony TV turns off immediately after turning on

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. Check this link to get more details about Sony Blinking codes.

Sony Trinitron clicks 5 times then standby light blinks 2 times every few seconds

It is due to over voltage form the SMPS power supply to horizontal output section circuit. If this voltage goes higher than normal, the set will shut down, showing two blinks of standby lights. I've recently found one site that details all these matters well. "electro-help' is the site name. Google for it. have all details, and I'm sure that you will get all details.

Tv sony stop after 20 min standby led flashes 3 times

By three blink it means the B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is because there is problem in the power supply circuit. Check for any dry soldering in the power supply side. If the tv is working properly for 20 minutes then its sure that there is some dry soldering joints in the power supply side. You have to resolder suspected soldering contacts using soldering ion and solder. The dry soldering joints will look like on in the picture.

SAMSUNG TXH1970... The standby light is on, but when I press the power button nothing happens.

There is some short circuit in the secondary side of the switched mode power supply section inside the circuit board. Now only the 5VDC is correct, as you see the standby light ON. The short is likely to the horizontal output transtor. Replace it first and see whether it helps you. If not line out put transformer is faulty, and should be replaced with same type and number..If any internal short occurs, the power supply protection system will activate, and shut down all other secondary power supply rails, as a protection to prevent further damage to more components, This is happening in your TV now. OK

Standby light blinks 7 times and tv will not turn on


Thanks for using FixYa. Standby light blinking 7 times means high voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. You’ll need to check power supply regulation and horizontal circuits. Please do accept the solution if the issue is resolved or else revert for further assistance.

Tv keep going on standby when you turn it on

tv goes into standby all the time if a power supply is not fine, what happens is that a power supply produces two voltages, one small one powers a standby components and bigger voltage powers a line transformer which later produces more small voltages,
then later cancels the first small voltage.

chec your power supply semi conductors like, transistors, diodes and small value resistors, on your power supply. some power supply uses a IC to oscillate a ht. so check a supply at a w/shop.

No power even standby LED..

This is like a car running without a driver,the horizonatl output transistor has the voltage it needs but it does not have horizontal drive signal applied to the base of the horizonatl driver transistor,the driver transistor should have a signal coming from the signal processor where the signal is generated just to get give it to the driver this driver then it gives it to the output to energize the flyback and light up the picture tube and generate a few other supplies,158 volts are there because the output is not turn on,try measuring voltage somewere else in the set and not at the collector of the output,there is a b+supply that goes to the signal processor(8 to 12 volts),check to see if you have this voltage,I couldn't tell you the pins in the siganl processor IC without squematic,It seems you know your way around tv service but be careful when checking voltages.Let Us know if you need more information.
