Question about Zenith R49W36 49" Rear Projection HDTV

1 Answer

ZeneithR49W36 question I saw you were helpful with someone elses problem..I am hoping you dont mind giving me some advice. The Tv i mentioned above looks as if some pressed a button to make it "widescreen"...but its so wide I cant see the entire picture. I can see everything on the left of the screen but not the right. The TV image looks "stretched" as if some one took each side and pulled the picture. I tried going in to the panorama settings and it does change it to a couple different settings but it still has that strectched look. Do you think my TV is dying? Or is this something that can be fixed?

Sounds like a defective capacitor or Diode in the deflection circuit. If you are able to test voltages you may be able to repair it very easially with testing the components in the deflection circuit. If not you may have to replace the circuit board.

TV will not turn on.


Sounds like there is a short in the tv somewhere, the clicking is probably a breaker/fuse inside the tv cutting power to prevent damage to the components. Have you tried a different outlet as they can sometimes cause this to occur by surging power to the unit.

The standby light is blinking 10 times


Hi,
TEN blinks - Check for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, "D" board.

High voltage in TV got problem and that's why TV gives 10 time blink error code.
Qualified TV tech will fix it as its bit complicated fix.

Parts are available but problem of High Voltage Protection (10 times blink) requires high expertise and experience of TV repair.

You must know how to test transistors, resistors using the multimeter if you are going to DIY.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to seek for an assistance of a qualified TV Technician to isolate the above faulty parts.

Hope I helped you.

I have a Hitachi 53FDX01B rear projector tv, that I bought from Audio King. Its starting to show blue lines on all 5 imput channels. Its a rear projector tv, 52'', what could be wrong with it?


It sounds like a convergence problem.

I will attach some photos for you to compare to your picture. No two sets when they have this kind of problem look exactly the same but you will know if it is the the trouble you have.

If it is a convergence problem I can give you options about repairing it yourself of having someone else repair it for you.


Keep in mind that I am in California and possible differences in time between where you and I are.

Look at the photos and let me know what you think, I am here to help.

I have a Sony KP-57WV600 with a similar problem described by someone else on this site. The screen turns red and stays red within a minute of turning it on. If I turn it off and back on again, it's ok for...


I have the same set, I was able to get the set working doing what was suggested on the site I posted below. Unfortunately I have other problems now. These sets are notorious for having failing CRT's (Guns, Tubes). These adjustments "should" help you buy more time out of the set. Sony doesn't make the CRT for these TV's any longer. You can get refurbished ones for around 200.00. Keep in mind there are 3. It is not really worth it, not to mention the time it takes to do the adjustments on the new tubes. If the set won't stay on long enough to do the adjustment, back the appropriate color knob back slightly then try again. I hope this helps.

Menu flashes on while TV is on


Now I dont want to step on any other repair shops toes as it were. so im going to give you some advice. I think your dead on about the switch. i have seen this condition here at my shop a few times and what i have done to fix it is replace the switch pcb cuircit board... this has fixed it 90 percent of the time. BUt....i have seen other problems that cause this.... there are 4 possibility in this case. 1 switch pcb. 2 bad infared sensor 3 bad cables. and unfortunatly the last one that bad main board. the other shop mentioned. Some condition is occuring that is telling that main board (processor) that "hey someone is wanting to see the menu"so put it on screen. for me that comes from the front panel and the remote sensor and the remote. since you have experience with some sets try this. ......remove the front panel real easy. remove the 4 torx screws in the back and remove panel its that middle one. disconnect cable from buttons turn it on with remote if the menu doesmt pop up then theres your problem. about the part and where to get it i believe union electronics sells rca parts.. you have to get the model number off the back and be sure to include the ext it will be hd52w59yx1 or something like that. well good luck and let me know if i can offer any more advice

Good Day, gongora326;
It sounds like the TV has some type of short in the power or high voltage circuits.
I would recommend that you call a factory authorized service company to come to your home and give you an estimate.
I hope you take my advice, good luck, big IRISH.

Hello Renrew,

There are several things that can cause it. You are best to have an expert technician come in and take some test on it in order to determine if it is from vertical blanking failure or something else. It is not easy to fix this yourself, if you have no experience, because there are a lot of parts that have to be removed before you can reach the components. It could be as simple as a loose connector ribbon or a bust capacitor, but it could also be more complicated. Hence, in my honest opinion, better get a qualified technician.

Hope that helps!


Thank you for using FIXYA!
