Question about Toshiba 50H81 50" Rear Projection Television

1 Answer

Wavy junping horizontal lines

My screen is covered with wavy and jumping horizontal lines. It started out when I first would turn it on, and it would take five to ten minutes to stop. Now it never stops. I can watch it after about an hour of being turned on, but it does not stop completely any more. Sure would appreciate a solution. Thanks

Requires the hyper board to be repaired . Has to be sent to Toshiba, unless you can change around 15 surface mount capacitors, They usually charge around 420 to 450 Canadian

Toshiba/ 42H81 / hyper board


You can either yrplace your Hyper board, or replace all the serfice mount capacitors in it. The cap replacement fixes this 90% of the time.

Toshiba 50H82 has wavy lines in screen for about


this is a very common problem in a lot of Toshiba sets of this type----bad caps(filter capacitors) on the "Hyper" board---it processes all signals in the set---it will start out where it clears up after warmup and as time goes by it will take longer and longer to clear up----the board is no longer available and the only way to repair is remove the one in the set and send it out for rebuild---most of the time this costs 3-4 hundred parts and labor(not worth doing)

Mitsubishi VS-45607 45" Big Screen


Good Day, Delano1981;

It may cure the problem but I would suspect the 9 Volt source
CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND
IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH
ARE ON THE SIGNAL PCB.

This should resolve your TV"s condition.

Good Luck, big IRISH.

Picture Jumps/flashes for first 5 minutes


There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.

Wavy Screen on Startup


I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.
