Sony KP-57WS500 57" Rear Projection Television - Page 3 Questions & Answers
Color problems
if you have hd cable or satellite box make sure the component cables are properly connected(green red and blue) and matching same color in source (cable box or satellite and tv as well)
also make sure in tv menu that color and tint are 50%
Fuzzy picture
You can't make SD look like HD thats why HD came out, the best you can do is adjust the picture controls to get the optium picture
Sony red out line
may be those two convergence ics they do go bad have ran the concergece on the tv it self
No Power to Red and Green CRT's
The resistors will have marked on the board under them a location number and should be little trouble to find.A factory service manual for kp57ws500 also should with the location numbers indicate a Sony part number and the value of the parts.What bothers me with the model is it is widely known to have bad picture tubes--it is a coin toss that if you replace the resistors they may instantly pop if a bad tube is involved.Get me the location number/s and I will see what I can find out.SD TECH
T.v. will not come on
Isee so many here with no sound/no picture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves
checkingvoltages on the main power board to narrow down the problem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over
Image on tv casts a red shadow.
TRY THE MAGIC FOCUS BUTTON. IF THIS DOES NOT CORRECT THE PROBLEM YOU WILL NEED A SERVICER TO GO IN AND REPAIR CONNECTIONS OR REPLACE THE CONVERGENCE IC'S AND OR RESISTORS. AND READJUST CONVERGENCE IN THE SERVICE MODE.
