I have a HAIER tv. model no is 21fa 18-t.picture ok no sound. But amplifier working ok system ic no is, 8865csng7ep1


Have you checked its speaker? Check it. If picture is OK, there should be sound, provided the settings to sound are OK; ie, sound system settings. Check the sound system settings once again. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Flip card, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window. google.com/+GopakumarGopalan

No picture. Sound is OK on Philips DPTV345 model 51PW9303/17F


I would check the solder on the Vertical output IC as ofetn the soolder will crack and the CRts will shut down to prevent damageing the CRts when vertical drops out. If the solder looks good I would try replaceing the vertical IC very inexpensive and you can get the vertical IC from www.tvrepairworld.com

Picture cutting after 5-10 min-raster OK sound OK


The vertical ICs on this particular model have by now bad grounds. You will have to resolder this, and check any and all grounds on ICs mounted on heat sinks! Bad grounds are common and plentiful. Good Luck and thanks for asking!

No picture when TV is turned on, sound is OK


try to look at its circuit board and look for cold solder or loose solders usually solders with crack,they might be the problem,i dont think its the flyback coz you have audio.try also look at its picture tube at the back tru the crt if the filament is ok or it may also have loose connections
