|
|
HELP HEEEEELLLPPPP!!!!!!!!!!!!!
First time CRT user... but I have a problem also:
I got two projectors Sony VPH-1251q "for free" from a good friend that just got his digital one... both worked fine (one at the time) I was able to do the setup and connected satellite receiver, dvd and sbos 360...used s-video and composite video to VGA cable also. All fine but on the first one all of a sudden it stop working...it would turn on for 1 to 3 seconds and gave me the error code 10 (means HV over) however, I have never had high voltage issues in my house.... I did unplugged and try it out a day later...al powered up ok but the it did the same...
Removed the projector, installed the spare one and it did just the same...so should I remvoe the video cards? I did unpluged all inputs and still getting error code 10 or HV-OVER error....
I am going to remove both input cards and see if one of them is giving me a short circuit...I am guessing one of the inputs migth have fluctuating voltage issues that is short circuiting the boards.... what do you guys think?

I did remove both video cards....s video card & RGBHV cards.... plugged in , power up....still , powers up for 2 seconds then goes off.... error code 10 (HV-Over) appears on led screen...
Again, it is just estrange that they worked fine for a week or so, then it failed, and then on the second spare unit the same story..... however, while working both projectors were giving me an "excellent" picture with both DVD, X-Box and Satellite receiber....
Any input would be appreciated, I really like these units, and I do not want to sell them as spares parts, but if I have no choice I will.... the RGB tubes are still in very good shape in one of the teo units, maybe at 70-80% of life left...so at least I could get some cash for that.... but I prefer to make the units work...
Other than the fuse near the main power switch by the main cord, are there any other fuses I need to check?
thank you

Check for bad seated connectors and bad solder joints on the 2 top boards.
This is where the HV power comes from.
I think this problem is more likely the result of the 1251's getting very old

Error code 10 is usually a bad tube or a problem on the PA board........

Hi
Check all the solder joints on the 2 boards (E and DC) you see as soon as you take off the top cover, remove them totaly from the projector and unscrew them from the metal frame the are screwed to, leave the heat sinks on but handel the boards with care as they are flimsy, the weight of a heatsink in the wrong direction will result in a crack / snap!
The wires and plugs are all handed so as long as you are not colour blind or cut calbe ties / unbundle the cables they will kind off lay in their position once unplugged, I would recommend numer mark with pen if you are not sure.
Now you can see all the solder joints (as there are several hidden under metal work (hence me saying remove from the frame) re-solder every single joint of every single device stuck to the heatsinks down both sides, I would be suprised if any don't have dark rings / cracks round them.
Also re-solder all the joints on all the other deviced stuck to the smaller heatsinks on these boards.
Check your work for any solder shorts if all ok stick it all back together and hopefully your working, if still no go check the boards on top of the power supply for dry joints as well.
Clean the fans with a paint brush make sure that thay all spin freely.
The other boards tend to be all "though hole plate surfcae mount" boards and don't really suffer from dry joints.
I have repaired about 30 of these PJs over the years and all had dry joints on the E, and DC boards causing lots of differant error codes and all worked after simpe re-solder, just moving from one room to another can set them off.
Make sure your PJ is off / unplugged from mains power and standby light is out before working on it.
Hope this helps

|

Hey guys....need your opinion again: I am ready to inspect and re-weld the boards to try to get rid of error code 10...now, the million dollar question, in your 30 PJs experience, should I start with the E board or the DC board? Just to save myself some agravation.... I just bougth the soldering equipment today, so I migth as well start with the rigth foot and board  ) greetings....

Hi
Well not an easy job but they both will need to be done I would go for the E board first then the DC.
I have got another VPH-1271 in today that's basically scrap / spare parts, it has burnt tubes with 12K hours and if I press on the DC and E boards it turns off with code 10 error, a prime candidate of what you will be hopefully fixing.
If you have any trouble get back to me and I will video myself taking this one apart and stick it on youtube or something.
PS, be careful of the board stay / latch make sure you slide it off / out ells your start to walk off with the top and find its ripped out of your hands.
PPS, under the wiring loom next to the speaker is the screw to remove the speaker so you can get to the hinge screws, undo the screw and slide speaker up or down (can't remember what way) once its moved up or down it lifts out.
Hope this helps,
MrCRTing

I am a mechanical engineer, never deal with circuit boards before ... it was NOT easy ... it WAS my first time... these are my findings:
Opened and removed the boards out of the projector ...out 100%
Did a through inspection and found only one of the two boards with yellowish oxide in it
Did grab a knife and carefully cleaned all the terminals with oxide
It is a 14 year old unit...all three CRT lamps work great
Put all back in place and I did not had any missing bolt....
Tried BNC cable from a DVD.... worked perfect
Tried S-Video also from FTA satellite.... works great.....
All connected to stereo....
I have a poor's man mini theatre... and I can NOT beat the price= FREE
I am soooooo excited... Now I will fix the spare unit....
Thank you thank you and 1000 times more thanks for your help my friends...
Anybody interested in a spare unit let me know and I will see if I sell it... I live in Ontario (near Michigan border)

Cool glad your up and running.
The 12xx series are not bad projectors I would prefer an EM focus unit to get the last little bits sorted but if a good setup is done these ES PJ's look darn good and can be had for a song!
Have fun watching,

on my second vph-1251q I went and removed the same boards....e & dc,,,, and I am glad to inform that none of my two crt have error 10 anymore, thanks for all of your support.... Ontario has two functional and resurected Sony CRT units.... I am able to see X-box, DVD, HDTV converter box and satellite,and all connected to a super old pioneer stereo amplifier with huge speakrs.... the only one I need to figure out is how to integrate my VCR
Now, to payback a bit, I did an 8 feet by 6 CRT feet screen using corrugated nylon white board, I did use small drywall screws and floor molding for the frame that was glued to the nylon boards to aviod dmaging the wall in case the wife didnot like it...but let me tell you, under 100 Canadian dollars and it loos top of the line and is a big diference comparing to reflect the image on the wall almond color alone....

if you don't know what a bad solder joint looks like, you starting to work on the board is a really bad idea. Not all error codes are due to bad solder joints, and if you don't know how to solder, you can make things a lot worse by starting in on something that isn't a problem in the first place.
I can test and repair both boards for $150 incl return shipping.

The projector section of this forum is to help people determine if there is a problem with their source components, connections or projector itself.
If it is determined the problem is with the projector then help is offered to determine which board or boards maybe at fault which you could then send to Curt for repairs.
This forum is NOT for help in technical repair at a component level.
Of course I'm sure you didn't know that.
