Question about Toshiba 57H82 57" Rear Projection Television

1 Answer

Wavy picture on all video inputs except component video toshiba 57h82

I had a slight wavyness happening on the top section of the screen that got better when warmed up. Also had a wavy picture on all video inputs across the entire screen. Then replaced the caps on the hyper board & it solved the wavy section on the upper part of the screen but I still have a wavy picture on all other video inputs across the entire screen. The component video input is crystal clear. If any one has any answers what else is wrong? Please let me know?

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

There is a Hyper Module mounted right behind the video inputs board. in most cases you can replace the 10uf surface mounts carefully not to tear the foil. and the set will return to normal. or replace the H/M board. this board is soldered 4 tabs on bottom of main board and then pulls out. good luck list of caps cz52(may not have this cap).. cx261 cx270 cx230 cx178 c514 cx221 cx250 cx241 cx541 cx670

Top section of the picture gets reversed and compressed


Dear simon, Seems like a simple problem. In all likelihood, one of the Electrolytic Capacitors in the vertical Output stages has failed.It could also be a cold / dry solder, as symptoms seem to disappear when you tap the set. But, do not try anything thing at home. A proffessional Techie should fix it up in 15-20 mins. Definitely worth the spend.
