Question about LG 42LP1D 42 in. LCD HDTV

Open Question

LCD Television Proview RX326

This is a problem that is hard to describe, but I'll try. At the top of the screen an area about 8 inches wide and a little left of center screen, the border (1/16 of an inch wide) has dropped down about 1/8 of an inch in an upside down arc. You can still see the action of the screen above the border line that has dropped. If you don't understand what I'm trying to describe, ask me some questions. The screen otherwise is fine.

I had the same problem and fixed it by replacing the control board. It's a little nerve wracking, but required only simple hand tools. If you'd like to see detailed pictures of the repair check out my blog.

SOURCE: vertical red line through screen

This is a problem within the screen, probably the connection from the internal ribbon connector to the display. Unfortunatly the only way to repair this is to have the screen replaced.

That can be the T-CON board failure or main board. It can be heat relate so you will need freeze spray for electronics troubleshooting to cool down the T-CON board first to see if it starts working again.
You should also check the power supply first to make sure it does not have any bad caps and the DC output voltages are OK.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Basic troubleshooting guide here:

Learn about bad caps:
Capacitors kit: he can make you a set of caps.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Please leave rating if it helps.

After 10 years with a Proview not Proscan RX326 TV, went from coax to HDMI from new Comcast digital adapter. Comcast & Proview remotes turn on TV but the screen often stays dark with no sound.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I live in Canada and subscribe to Shaw cable system. I need a 4 didgit code for my Proview RX326 LCD TV so I can program it into the Shaw remote control

There may not be a code set compatible with your Proview TV since this brand is not that widely distributed. The code sets available in any remote reflect the brand names and feature sets of TVs (and other entertainment electronics) that prevailed when the remote was designed. Even the so-called 'learning' remotes will not program to every InfraRed remote.
Your best chance is to check Shaw's website for the most recent codes:

What should I see on an oscilloscope at the 8 HV outputs to the backlighting of the RX326? Is a line isolated scope with balanced input required? Thanks, E

You are talking about over 1000vac at start up and about 500vac after the lamps are lit, it will have variable pusle width depnds on the brightness setting. I wouldn't put the scope probe there. I would use a small fluorescent lamp or test lamps removed from other TV for testing. What is th symptom? I would also Ohm out all the transfomers for open or shorted winding, no blown MOSFETs?

Permanent Vertical Line on my Sony Bravia 46 inch LCD TV

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

Check-out the Proview website
go to tech support and e-mail a lady by the name of Kamisha Fernandez. She will email to you the user manual. She did for me and it was a great help. But what I need is the electronics schematics to the RX326 if anyone can help out on this matter.

Pat I do not know if you have a warranty you were required to retain the receipt from the store for the length of the warranty period to prove you have one ,also it is a good idea to register with the company on their website so they have a record of your tv and model, with your name and therefore the warranty they have included if any.LCD tv's are one of the most unsupported mass marketing consumer items that are being dumped on the US market. I think you have Blown capacitors, or more likely a problem with the power board, typically this requires soldering new capacitors onto the power board after unsoldering the blow ones and if this is all the problem is the issue will disappear, if there is an issue with a transformer, or some diode or computer chip then you might as well replace the whole power board. the capacitor issue is no big deal if you can get an electronics service center to look at the problem.
