Question about Daewoo DSP4210GM 42 in. Plasma Television

2 Answers

Our 42" plasma tv will not show a picture or anything else.

We were told the power supply was bad but the tv's power button will turn on and off. When we turn it on lines appear for a second then just a light screen. We have searched everwhere we could possibly think of to try and find a power supply but the answer we get is it has been discontinued. It's a Daewoo 42" Plasma. The model number is PD42S20W, and the serial number is DDPTCCA00962.

My plasma TV will turn on, but there is no picture.

Wow so you've spent a lot already. I'd buy a new tv dude. It sound to me like something else has failed on a power board and they just don't replace small parts anymore you need to spend the money to replace the boards usually unless you find an old school TV technician willing to do it. It could be a the power supply so before you try anything costly see if you have a similar power rated supply around the house and see if that is the problem. Good luck. + Google the issue and you may find it to be a simple answer.!

Vizio 50" plasma

Was there a pop noise before this happened or is there anything flashing at all?

The power supply in these sets have had bad electrolytic capacitors which short and actually blow their top because of increased pressure. Only part of the switching power supply is now running so you may see a power light but nothing else. I am not sure what Vizio would charge to replace the cap or supply. If this is the problem the capacitors will be fairly cheap and depending on your skills, the labor may be too but capacitors are dangerous and only a qualified person should replace them.

Please let me know if you see anything else that may help figure out what is wrong, thanks

Tv turns on but no picture. Then Tv shuts off by itself.

Try turning it on again and quickly press the source button several times until the source menu on the screen appears. Keep trying this method, and if the tv does not do anything then it needs to be serviced. If the tv turns on and functions normally after this wacky method then your power supply is developing a problem....its probably a bad capacitor or TO style diode.

All you can do at home is leaving the TV unplugged for one or two hours and see if this solve the problem.

If the unit has just been repaired, and it is faulty again, contact the service back and have the problem fixed.

Common faults on plasma TV can concert the PSU power supply board, the sustain boards, and other boards, wiring and connectors.
The testing and repair job must eb done by a technician.
