Toshiba 57H82- Distortions on the picture screen

Distortions (wavy lines that flicker) were present on the screen and usually went away or faded significantly as the set warmed up. Now the distortions don't go away at all.

My 57h82 picture has picture noise in form of small jagged/wavy lines at edge of objects - particularly noticable for text or numbers. This appears on all channels and with all input sources. How to fix?


Is a common problem. Your hyperboard has failed. You can get a repair kit from www.TvRepairKits.com or buy a used hyperboard - but it will also fail someday unless it has been repaired with better parts than what the factory supplied.

Sounds like a bad tuner/decoder on the Qam analog side of things. You can bypass this with a Clear qam converter box or a analog to digital tuner box or simply having this repaired upwards of $200 bucks.

About two months ago when we first turned on the TV there were wavy lines across the whole picture. When it warmed up they would go away. Now, the lines are there almost all the time and it's getting...


hi
You are experiencing a lack of vertical deflection or vertical collapse. Since it will come back the first thing I would suspect is “ring cracks” in the solder joint in the vertical circuit, mainly the vertical IC. These suspect solder joint can be re-soldered and the television set repaired.
I would suggest that you contact a local servicer. If you are repairing the set yourself, be careful, there is always a risk of shock when dealing with electronics.
OR
Check your equipment connections. Disconnect your equipment (VCR, DVD or set-top box) from the TV and reconnect, making sure each connection is in tight.

Slight convergence problem after changing convergence circuits


My experience has been that the resistors have fallen out of range. These aren't expensive and neither are the caps that surround this area. If you're pulling the board out to change the resistors, might as well change the caps, too. If you're strapped for cash, but have a multi-meter, you can test the caps and the resistors after they've been taken out of circuit to save a little green. Let me know if you need any help testing them; I'd be glad to help.

Wavy picture on all sources


This is a somewhat common problem having to do with the hyper module, Toshiba p/n#23148024 There are a gouping of 16v/10uf caps in the hyper board that fail causing the distoritions you're describing here. At first, as the module begins to go bad the distoritions are present and usuallly go away or fade significantly as the set warms up - - this gets worse until the distoritions don't go away at all... From what you're saying you're at stage three already. :) You have a few of options: (1) local repair shop pull the board and replace the caps or module; (2) Pull the module yourself and repair or send it in for board level repair; or (3) pull the hyper baord, order a new one and put it in yourself. For 2 or 3 you'll be better off having the service manual and if you need it just email me privately and I'll send it. Make sure in your request to tell me the model number and reference something of this repair so I have a clue of what you need. BTW the hyper board is on the left side of the unit mounted vertical on the signal board inside a metal can. Good Luck Bill
