Re: Samsung PS42S5hX

Very simple your problem in vertical section. as you say that slight tap brings normal so there is no parts failure it is due to loose contact in vertical section mostly ele.capacitor in feedback ckt.

I have a samsung tv , model code. ps42s5hx/xex , version sa01 ,, the symptom is showed on the picture (black on the left) what should i do to resolve this problem? I am a local tv engineer in Albania

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

42lh3000 Right half of screen is black but goes better when warms up, still flickers at times, how can i repair this? The tv is about 2 years old and never had a problem with it before, the sound is great...

I have fixed an LG 42LH3000 with this very problem. Large TVs have a tendency to flex and bend ever so slightly when being moved or through heat, this can affect the connection of the ribbon cables at the top of the screen - either at the end where the Tcon board is or where the screen driver board is. When one end of the cable loses contact, half the picture goes (there are two ribbon cables. one for each side of the screen).
Remove the cables then carefully reattach them. If you still have an intermittent problem would suggest leaving the screws out of the T-con board as this will give the ribbon cable more slack.
Don't attempt any of this unless you know what you're doing - risk of damage to screen if handled indelicately also risk of fire when plugged back if the ribbon cables aren't secured properly.

Faulty parts on PS board , bad press for Samsung

Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

No picture, sound ok

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use

I also have the same problem I phoned Samsung today to explain the tv was only 14 months old, they didn't wanna no because it was out of warrenty by 2 months. I am getting a black solid line down the left hand side of the screen. I ended up phoning Dixons were we bought it from, they have told me to get an independent engineers report done & send the report to them within 14 days. Dixon told me it was a known problem with Samsungs. They said they will fix it free of charge if they can if not they will send vouchers to the same value of the television. So beware stay clear of Samsungs.

This could be caused by the Y-main board or the lower buffer board going bad
