TV Basic Repair Guide: Common Problems


This post is for those who want to know the common problems that we will encounter in repairing Television set. I will be posting some common problems and their possible solution and tricks to repair this problem.










(Made In China Universal Board)

DEFECT: Single Vertical Line In The Center


1.) Check first the vertical IC. Some Vertical IC’s may have loose contacts on solder joints on its legs because of the heat and cold condition on its operation.

2.) Check the supply voltage if present in the main vertical section, sometimes 24 volts from the flyback and other supplied by 24v and -24v plus ground.

3.) If the supply voltage is missing, check the line from flyback having 18-24 volts, possible culprit is an open fusible resistor.

4.) Defective yoke, maybe there is a broken or burn part of the coil inside it.

4.) If the supply voltage is present, possible problem is that the Vertical IC is defective or the Vertical Sync coming from the Jungle IC, better to check also the jungle IC in this situation.



1.) Defective yoke, maybe there is a broken or burn part of the coil inside it.

2.) Loose contact connection on one of the legs of the yoke on the main board.

3.) Defective non electrolytic capacitor.



1.) check first your speakers, it is usually the most common culprit after repairing a television with power supply problem based on my repair experience.

2.) Check if the supply voltage for audio ampifier is present, if not check the line.

3.) If the supply voltage is present, try doing a hum test by touching the input of the audio IC, refer to the datasheet to find the input pin of the IC. Replace the audio IC if everything is done.



1.) Check first the power cord.

2.) If the power cord is ok, check the fuse
( note the fuse is burnt, don’t replace it right away. Check first the circuit if their is a short on the circuit specially on the primary power section, check all the diodes surrounding the main power IC)

3.) If their is no shorted diode and no short on main IC, now check the Horizontal Output if it is busted or shorted.

    please help

    • Frank says:

      Hello Deirdre
      it seems your problem has to do with the vertical section try to resolder the vertical Ic and some components arround it if it doesnt work replace the Ic.

    hi there

    I’m sitting with a very old crt tv, it just won’t come on. I’ve read what you posted on that but is there maybe any other reasons or solutions if it still doesn’t come on.

    • ronelex says:

      Its better to let it check by a certified technician, doing it on your own without the right knowledge is hazardous. TV is so dangerous to repair specially if you don’t have the right knowledge

    i want to know tv china,how to repair it

  28. Sir plzzzz help,
    My CRT TV Samsung(CS21A551ML/YEAR 2011) have half screen problem.
    The problem is that only bottom size works well but top half size goes black with green,blue and red thin lines appearing on top side.
    This problem occurred in last year for few times,the problem fixed automatically after few minutes without touching a tv.But from last 3-4 days problem again occurs but are still there,,,,,i open my tv set to check whether their is any loose connection but don,t find any loose connection!

    Sir what may be the problem plz help!

    • ronelex says:

      The problem lies on the vertical section of the TV circuit, try to locate it and check for some cold solder and resolder it and check all the capacitors in that section maybe one of them is open or leaky.

  29. carl winter says:



    • ronelex says:

      Try checking the capacitors on the power section if their is one them open or leak.

      • paul says:

        Sir papano poh ba magtroobshoot sa crt 21 samsung tv kung ang horizotal line in the center of the screen?

        • ronelex says:

          yung verical section na ang sira nyan, Check mo kung may supply na pumasok sa vertical IC, check mo rin yung mga capacitor sa vertical section if ok lahat maybe the Vertical IC is the defective

  30. Waqar Azim says:

    Dear Ronelex, your thread is very helpful regarding the TV issues. Your efforts are appreciated.

    I have National GL TV. When I want to Turn it ON whether by remote or it’s ON OFF switch it does not turns ON. I have to try more than ten times and then it picks power and turns ON.

    Please help me in this regard that which device is responsible for it.

    Thanks in advance.

    • ISAAC says:

      Since the fuse is ok first check for burnt of open power resistors if all checked ok then change the main power IC, REGULATOR of TRANSISTOR, they are always attached to the heatsink at the primary of the power supply.

    Mga sir Pa Help PO.


    Pa i on mo POWER button swicth,may maririnig ka na crackling or frying sa loob…,pero may sounds po ang tv BLACK SCREEN nga lang & no RASTER.

    Actions Taken:

    Baklas ko ang unit at nakita ko na sumisingaw ang HV sa mismong rubber duct at tube contact,so na isip ko na baka madumi na iyong loob ng HV contact,so discharge HV ko then linis ko na HV contact sa picture tube & after that ikinabit ulit duct at test ko presto wala na crackling na maririnig pero black screen pa din,sinilip ko naman HEATER ayon open ang resistor so palit ako ng resistor ohms value ikinabit ko kasi na sunog iyong orig resistor niya di ko na makita kung ano value non.

    So after pinalitan ang resistor ng heater filament sa board,sa una nag ok siya may raster na umiilaw na..,but after a couple of minutes nawala naman ang raster so sinilip ko na naman ulit ang resistor at test with analog tester but the resistor is GOOD…,Isip Isip ulit..

    After isip isip..

    Try ko ulit i on ang tv ayon may naririnig na naman ako na crackling or frying,so this time wala na doon sa picture tube ang singaw ng HV, doon na naman sa may bandang leeg ng rubber duct ang sungaw ng hv,doon ko napansin na may tapal na pala ang flyback niya sa may bandang leeg ng rubber duct at sa flyback din mismo meron din tinapalan ng epoxy or devcon yata iyon.

    So may nakita ako na epoxy or devcon so tinapalan ko na lang ulit iyong parte na may sungaw ng HV..,after 1 hour pina andar ko ulit at presto ok naman ang unit may display na ulit..,but after ilang minuto ayon ayaw na naman mag display.

    So sa kakulitan ko pina andar ko na naka hang ang likod palad ng kamay ko sa front ng tv..

    Pero na shock ako kasi napakasakit iyong kuryente na tumama sa mga DULO ng mga daliri ko at that time medyo padilim na kaya medyo naaninag ko din iyong kuryente na parang pumapasok doon sa may yoke coil ng tv while pia ON mo ang tv.

    Na isip ko na iba na ito ah masakit na itong kuryente niya na supposed to be ang na fe feel lang natin eh parang TUMITINDIG lang balahibo ng likod palad natin.

    Sana na gets niyo ang ginawa ko na report about sa kinukumpuni ko na tv ngayon at sana matulungan at mabigyan ninyo ako good pointers or guide.

    Salamat po.

    hi my brother, I have a 74cm china CRT TV. I have checked all the primary components; changed hot transistor. The heat sink is heating normal; I do get 300V+ across the main cap that also reaches the base of the hot transistor. The problem is, I don’t get the secondary voltages (90V -110V) at all; and the LED does not light. Can I suspect a chopper on this case or can the secondary be also responsible for the LED?

      If you have some knowledge in electronics, you can try to resolder the legs of the components and if the problem still there, maybe it is caused by a leaky capacitor. Just have it look by a certified technician :)
