How to Repair Samsung Plasma TV PN43D490 PN51D490 PN51D450 PN51D550

TV has no power and there is a clicking sound (relay). The most common problem among these models are faulty transistors in the X main board. Replacing the x-main board will fix this issue.

i have a 43d450a2d that only clicks when the video board is connected. i've replaced the video board but it still clicks. if the video board is not plugged in but all the others are, the relay wont click. anything else i should be looking for? i was so certain that replacing the video board would have fixed it but i was wrong

[@refrigerationunits6361]

Ps51f4500ar red light blinking 6times, what must be the problem?

[@hestheMaster]

Power for the X Main comes off the Y Main. To check it if its bad disconnect the black wire at top of the X Main to confirm the dead shorted transistors on the x main board!

[@joeblack02051999]

could you explain more? my PS51F5500 gave loud pop sound, then totally OFF, red front led ON for few seconds then off , green light at the board blinking slowly. I am not sure which board is the isue.

Pak tv repairs thanks for this folt

[@johnlucier8572]

You need to test all of the mosfets not just two and two on the ot&er end. You can purchase these parts easily. I had no problems replacing them. Replacing the board is not wise some times..

Hi there, thanks for the sharing your videowith evryone , I have shut off problem with my Samsung Plasma Television 43″ PS43E490, Sometime it works for days without any problem and sometime it shut off after 10 to 20 minutes and Red Light flash 5 times, If i remove the power cable and reconnect the cable again then tv does come on. So it doesn't happen all the time. I really appreciate if you could help me to fix this problem.

[@snoopda1andonly]

+A Lolouh Hi, does the light flash in a cycle 7x the solid?

[@alolouh6785]

+Runforlife Hi, ant thanks for reply . Standby light goes not in cycles, only when you switch it on at the beginnig . 7 times blue flashing and then stays blue. after a while returns red. And the green flash led on Logic board does not flash at all.

[@snoopda1andonly]

+A Lolouh This model is known for having issues with the X-main and Y-main. Can you check the fuses on both? and check some mosfets on the X-main and Y-main? You can check out my my other video on how to test a mosfet here: kzbin.info/www/bejne/iJy6qmR7ntd4q5o

[@alolouh6785]

Thank you verry much, fuses on power supply are all ok., and the litte once on Y- main also. I wil check more mosfets . What do you think about some other telling on the net that the eeprom Pic 24xxxx can be corrupted? (Little ic near the reset button).

[@snoopda1andonly]

+A Lolouh check the following in the Y-MAIN: FS202, Q16, Q11, Q12, Q13, R503
