Question about Daewoo DTQ-27S3FC 27" TV

3 Answers

Popping sounds I have a Daewoo tv, it's about 4 years old. It worked except it had a very very slight problem. The screen would pop (get a tiny bit bigger -only my wife noticed it) for a split second every 45 seconds. Now the sound and the screen both pop (the sounds cuts out) for less than a second but it's still annoying. Is there anything i can do? I hit it and it went away for a while but it keep coming back.

Loose connections or cold solder can cause this problem. Try to resolder all connections in the sound and video sections. Especially the video jungle IC section where the sound and video (IF) can be found. Good luck!

That my friend is the high voltage transformer with a tiny pin hole allowing the high voltage to arc to ground. The red wire going to the picture tube is carrying 30 thousand volts to the anode connection on the CRT. This is not a consumer replaceable part as the CRT can retain healty voltages even when off. Refer to a local TV technician.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Check the lamp to see if it popped. Try replacing it. Also check the web for class action law suit for these sets, Toshiba has an extended warranty for lamps for certain units.

32 RCA makes popping sounds


It needs a new FLY BACK transformer. That is what you are looking at. The origionals are not made for the set any longer but insist on having a generic on installed by a local TV shop. I just put one into a RCA 31" and it works nice. Don't throw away the TV. Get it fixed. MAKE SURE YOU INSIST THEY USE THE GENERIC ONE! THEY DO WORK!

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer

samsung pn64f8500 boot loop with evoulution kit 3000za installed I had perfectly working Samsung plasma ph64f8500 working fine with Samsung evolution kit 3000 ZA installed. Then we moved I took off the evolution kits so the movers would not knock them off. I powered up without the evolution kit installed accidently. Now both plasma are stuck in boot loop. They power up but go to the smart tv logo and cannot find the evolution kit. I read somewhere a long time ago that I needed to reset the evolution kit to a state where it had not been installed. The current issue is the Main Logic Board eeprom instructs the unit to boot correctly but it cannot find the evolution kit. If you boot without the evolution kit the system halts and indicates on the screen the evolution kit has been uninstalled and you must install it if you wish to view. If it could find the evolution kit one could go thru the menu to uninstall it correctly. One option is to manually reset the eeprom to remove the install instruction that boots looking for the evolution kit. I have been looking for the eeprom on the Samsung main logic board but I cannot download the logic board schematic. I cannot find the logic board number. The main logic board is BN94-0625C. The logic board has tow other part number references.• MFR Part Number 1: Samsung BN94-06205C • Board Number(s): BN41-01998A, BN97-06633G i have been researching the logic board IC Numbers and belive that IC 1701 is the eeprom that requires reset. The youtube videos for similar models indicate a eeprom that is listed as a part nmber for this samsung pn64f8500 unit as 24C512 and shows how to jumber 2 IC locations that will force the eeprom to reset to standard starup without the Evoution Kit 3000
