I feel ya, it is very expensive to get a tv repairs for normous fact's, keep in mind it cost money to have a shop going, insurance, gas expenses, labout, goverment what also there share, training, tele, heat hydro, cable, most info or from enternet, everytime you have a outside shot, bingo, the tele is double, cable, more money for insurence,,,, bla bla bla.
Your problem is convergence, I haven't worked on this model yet, but zenith, bad choice, in the set check to see if you have fused link to the two big grey ic's knowed as convergence it's, they should have +/- voltage on the ic's pin's mostly 30volt dc. and - 30 vcd. These ic's should say stk on them like stk392-150 as excemple. keep in mind you can order the hole bord, sometime it is cheaper, contact zenith help desk for parts to see how mutch they cost..

If you need more info send me the ic's part # on them or go on googles and it will tell you the pinout voltages once's you find the magn. info.

I hope this help

I have sound and no pic ona zenit model number r57w46

The set will turn off the three picture tubes for several different reasons:

Voltages including High voltage are not there

Loss of either Vertical or Horizontal sweep

Loss of secondary voltages to the tubes

The set "looks" at several things when turned on and if not there no brightness is the result--rarely the picture tubes but something missing or wrong.

Whenever there is a a spark or a flash it generally means high votage(HV) is arching either from the flyback, one of the CRT's or HV splitter/Focus block where the HV is created - It will be easy to diagnose but probably expensive to repair. Parts costs- Flyback and HV block $100-200 and CRT over $300

I want to buy zenit camera фото cнаипер

Cameras suitable for the Zenit фото cнаипер (Zenit Fotosnaiper/Zenith Photosniper) are usually very difficult to find as they're specially modified versions of normal Zenit SLR cameras which incorporate a special additinal shutter release button on the baseplate.

Photosniper versions are generally expensive but broken ones can be cheap. Regular Zenit SLR's are very cheap and often free on Yahoo FreeCycle but I've never yet seen a Photosniper version on there.

Ebay is a good place to look but normally they are sold as part of a complete Photosniper kit. If you do see a body only for sale then the Photosniper versions always have a letter "S" at the end of the name, so a Zenit E is a regular model and a Zenit ES has the modification which makes it a Photosniper SLR.

All Zenit SLR cameras are mechanically very simple and most do not have any complex electronics. This is good, because it means that you can buy a cheap broken Photosniper camera and a cheap regular Zenit SLR and swap the baseplate with the additional shutter button to a regular Zenit to convert it for Photosniper use, the modification usually involves drilling a few holes but it's not difficult.

Hope this helps you to find what you need.

Sony widescreen projection TV -- Model KP-51WS510

The tv is in shutdown protection due to overdriving video signal. If you are handy you can pull the front cover off and there are 6 controls on a HV block. 1 set says focus, do not touch those. One set says screen. One at a time turn them down, counter clock wise putting each one back where you found itTurn the first one down and then turn the set on. Do this for each untill you get a picture. You will most likely find a bad blue gun. You can also remove the board from each gun 1 at a time with the set unplugged and find the shorted gun. good luck.
