Moniter horigantel output transister open agan

Check the freewheeling capacitor connected to the collector of this switching output transistor for open. Check the serial resistor too.

Open your TV/s back cover. Pull out the printed circuit board. Place it at a convenient position. Locate the vertical output section. Locate the vertical output IC. Desolder it out from the board. Replace a good one in place. Solder all its solder terminals. That is all.

The problem is with your power supply. There should be a big round transister on the power supply this is the power transister. It will be mounted to the power supply case. Replace this transister and try to operaste your radio again. Make sure that the power supply you use is at leat 7 amps or the radio will not operate properly and you will possibly blow the transister again.

Sir 1- Use heavy ampier transister for hor output
2-measure h output transister base and emitter resestance value it is nearabout 15to33 ohms,you can use.
3-check lot by replacement

Hi
Dear sir,

Moniter Modale No E700,

E700 modeleprablem, Power splay prablem, but transister, Divaid all componets ok
Becouse power on that puse shout way to andstrading the prablem, please solve prablem

On your CRT back PCB thers three transistor on for red green and blue its possible that your blue transister is faulty. Try moving your cable see if the colour changes it can also be a faulty 15pin plug
Have a nice day

I WANT THE SERVICE MODE CODE FOR MODEL NO: DP21E101 TCL TV 21"

lg g505 this moniter 5 or 10 mnt woking then hot transister is damaged why this problem ?

Check horizontal output transister short. Check AC fuse open. If it is open check powersupply section any short circuit and check PTC.

Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
