Contact me. I have saved literally dozens of the 510/610/710 series by now, many of them sent to me from across the country, like Denny did. Even one from Canada.

If your set is still working properly with only intermittent bouts with these problems, I can all but guaranty that my resoldering technique will get you up and running again. I have been 100% successful so far, on boards being sent and on-location repair as well, under the condition that it is still in good working order as we speak, aside from the intermittent problems.

But for now, SHUT IT DOWN. Don't use it again until fixed. Others have not, they have continued using it while hurt, and have paid the price of more extensive damage, which never shoulda happened. This kind of thing is like needed dental work - it never gets better on its own.

I have a 37"Samsung LCD and having just spoken to the Sky engineer (also a friend) he says it is a national problem between Sky+ and Samsung. I have the same problem when on playback but not on real time? If you had your box changed to an Amstrad what sort did you have the problem with?

SOURCE: Optoma RD50 Picture Flashing ghost images

Hello! Just a little additional info if you will on what might to expect. This is according to the repairman where my tv is still in the shop after almost 2 wks because of the need for parts: other than the lamp the only place to get other parts (ballast and color wheel) is from Optoma and if yu need the color wheel you will have to purchase the entire assembly ($999.99) because they do not sell it separately. If anyone knows differently please let me know for I am between a rock (not really) and a hard place.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?


The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

Mitsu vs-5042 Works then picture goes out. Thumping works sometim


If you occasionally have a picture then you stand a good chance of repairing this tv. There are bad grounds on the deflection board. Start with the board that has the flyback. I do not know the year of your tv. Sometimes the same model may have an option improvement than one couple of months earlier. The first suspected problem would be the vertical IC. In some cases this ic is located on the convergence board and in others the flyback board. It has seven pins and is the TDA version. Located on a large heatsink. Resolder this and any other grounds on both board. Some will tell you the P I P board is bad. This is a free standing board that can be removed and replaced. But please do the earlier option first.

We have had our RU-60SZ30 for almost 3 years. After 13 months it did the same thing, LG covered the cost of the part,($3000.00) according to their certified repair center, but they charged us $500.00 for labor. Now today, 15 months later it is doing it again. I just got off the phone with LG and they say "too bad, you're out of warranty" So my TV that I paid $4000.00 for, has gone out twice in less than 36 months and LG says, "Oh well" After searching the web I found a law firm in New York that looks like they are putting together a class action suit regarding our model. Go to WWW.ZLK.COM/ZENITHTV.HTML and fill in the questionaire.
