Question about Projection Televisions

Open Question

I have an LG RZ-42PX11 42" Plasma TV, last week it started to flicker the picture for a min or so when switched on, now when it comes on, the picture is extremely grainy, accompanied by a loud buzzing that seems to be coming from the PSU. Picture flickers all the time now and cant get to full brightness. Anyone got any ideas ???

SOURCE: Plasma TV buzzing

If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.

Blue light remains lit but lose picture. no other indicator lights flash. if i unplug the tv it will restart but lose picture again after half hour


I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.

I have a Hitachi 50GX49B, when I turn it on red light on panel comes on, but no picture or sound. 4 weeks ago picture would come on, but would break up and dissappear until warmed up, this took about 2-3...


if you bang on the TV or try kicking the very center bottom of the tv and it works or flickers you got a loose solder connection somewhere on the board. I got the same problem. When it warms up the solder, around what ever pin it might be, makes better contact. I am looking into the problem and will post my finding when i figure it out.

Lg with a mind of its own


My REsz21rd is doing the same thing, switching off after a short time and then struggling to re-start. The LG repairers say it's the projection engine and have quoted £2000 for a new one. What a joke!

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.


Hi
The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.
